BEFORE YOU DECIDE TO BUY OUR COMMON STOCK.
    
                                  THE COMPANY
   
    Rubio's Restaurants, Inc. owns and operates 67 high-quality, quick-service
Mexican restaurants under the name "Rubio's Baja Grill" located principally in
the southwest region of the United States. Our restaurants offer a distinctive
blend of high-quality, traditional Mexican cuisine combined with fresh seafood
fare indicative of the Baja region of Mexico. Our menu contains appealing
Mexican offerings with distinctive taste profiles prepared from fresh
ingredients. Our traditional menu items such as tacos and burritos feature
marinated, chargrilled meats and other high-quality ingredients. Adhering to an
overall emphasis on freshness, we prepare our menu items on-site and
made-to-order, with each location preparing its own chips, salsa and guacamole
fresh every day. Our menu also features our signature Baja-style fish taco, and
is accentuated by seasonal offerings including our lobster burrito and tequila
shrimp burrito. Most of our restaurants also offer a selection of Mexican and
domestic beers. Prices range from $1.79 for a Baja-style fish taco to $5.69 for
a Cabo Combo, which includes a shrimp burrito, fish taco, chips and beans. We
strive to provide superior service in a setting designed to promote a casual,
relaxed and fun experience for our guests. We design our Rubio's restaurant
decor to be reminiscent of an authentic Baja beach setting. Most of our
restaurants feature saltwater aquariums, surfboards and outdoor patio seating
beneath traditional palm-thatched umbrellas, or palapas.
    
   
    We seek to differentiate our restaurants by combining the high-quality
Mexican food expected in casual sit-down restaurants with the convenient counter
service of quick-service restaurants. In this respect, we believe the "Rubio's
Baja Grill" concept is uniquely positioned between the quick-service and casual
dining segments of the restaurant industry. The critical components of our
concept include:
    
    - providing distinctive, flavorful Mexican cuisine;
    - creating a fun and relaxed atmosphere with authentic personality; and
    - offering our guests excellent dining value.
    We believe that our restaurant concept has broad national appeal and that,
as a result, we have significant opportunities to expand our operations and
generate attractive returns. Our business objective is to become the leading
high-quality, quick-service Mexican restaurant brand nationwide. Key to our
expansion plans and success at the restaurant-level is our business strategy to:
    - create a distinctive concept and brand;
    - achieve attractive restaurant-level economics;
    - execute disciplined expansion; and
    - ensure a high-quality guest experience.
   
    We believe that our restaurants provide attractive restaurant-level
economics. In 1998, the 43 units open the entire year generated average sales of
$901,000, average operating income of $148,000, or 16.4% of sales, and average
cash flow of $183,000, or 20.3% of sales. Comparable restaurant sales increased
10.4% in 1998, following an 18.0% increase in 1997. Net income for 1998 was
$915,000, which compares to a net loss for 1997 of $1.0 million. We currently
have 12 units located outside California. Of these, three units have over 12
months of operating results. These units generated average sales of $972,000 for
the most recent 12 months, average operating income of $149,000, or 15.0% of
sales, and average cash flow of $200,000, or 20.5% of sales. We opened eight
stores in 1996, 12 in 1997 and 16 in 1998. Our current expansion plan calls for
us to open 28 restaurants in 1999, of
    
 
                                       3
<PAGE>
   
which eight have opened to date, and 36 restaurants in 2000. Four of the 20
units we plan to open in the balance of 1999 are currently under construction,
and the remaining 16 have signed leases. We intend to continue to develop
restaurants that will require, on average, a total cash investment of
approximately $380,000, including pre-opening expenses of $20,000.
    
    The Rubio's Baja Grill concept successfully evolved from the original
"Rubio's, Home of the Fish Taco" concept, which our co-founder Ralph Rubio first
developed following his college spring break trips to the Baja peninsula of
Mexico in the mid-1970s. Ralph opened the first Rubio's restaurant with his
father, Rafael, over 16 years ago in the Mission Bay area of San Diego.
   
    We were incorporated in California in May 1985, and reincorporated in
Delaware in September 1997. We have a wholly owned subsidiary, Rubio's
Restaurants of Nevada, Inc., which was incorporated in Nevada in 1997. Our
principal executive offices are located at 1902 Wright Place, Suite 300,
Carlsbad, California 92008. Our telephone number at that location is (760)
929-8226. Information contained on our Web site, www.rubios.com, does not

- ------------------------------
   
    Please see note 1 to the consolidated financial statements for an
explanation of the determination of the number of shares used in computing pro
forma net income per share.
    
    Comparable restaurant sales are determined based on sales for stores which
were in operation for the previous 15 months.
   
    The as adjusted balance sheet data listed above reflects the sale of
2,250,000 shares of common stock offered at an assumed initial public offering
price of $10.00 per share after deducting the estimated underwriting discount
and estimated offering expenses payable by us. Please see "Use of Proceeds" for
information regarding our anticipated use of the proceeds of this offering and
"Capitalization" for information regarding our capitalization following this
offering.
    
   
    Fiscal years 1994 and 1995 ended on December 31. In 1996, we began using a
52- or 53-week fiscal year ending on the Sunday nearest December 31. Fiscal
years 1996, 1997 and 1998 each consisted of 52 weeks. The three-month periods
each consisted of 13 weeks.
    
   
    Net income (loss) attributable to common stockholders includes the effect of
the accretion on the redeemable convertible preferred stock which reduces net
income (loss) attributable to common stockholders for the related periods. Net
income attributable to common stockholders for the fiscal 1998 diluted earnings
per share calculation is $915,000. The difference from the basic calculation is
due to the reversal of the accretion on the redeemable convertible preferred
stock as such stock is assumed to be converted to common stock for purposes of
the diluted calculation.
    
   
    Net income for fiscal year 1998 was favorably impacted by the reversal of a
$452,000 deferred tax asset allowance that was previously provided for in fiscal
year 1997. We eliminated the valuation allowance in 1998 due to our belief that
current year activity made realization of such benefit more likely than not.

                                  RISK FACTORS
 
    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CONSIDER CAREFULLY THE FOLLOWING INFORMATION ABOUT THESE RISKS, TOGETHER WITH
THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, BEFORE YOU DECIDE WHETHER TO
BUY OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR
BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION WOULD LIKELY SUFFER. IN
ANY SUCH CASE, THE MARKET PRICE OF OUR COMMON STOCK COULD DECLINE, AND YOU MAY
LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK. ADDITIONAL RISKS
AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT WE CURRENTLY DEEM IMMATERIAL
MAY ALSO IMPAIR OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION.
 
    RISKS RELATED TO OUR BUSINESS
 
   
    OUR PLANNED EXPANSION INTO NEW GEOGRAPHIC AREAS INVOLVES A NUMBER OF RISKS
WHICH COULD DELAY OR PREVENT THE OPENING OF PLANNED NEW RESTAURANTS.
    
 
    Almost all of our current restaurants are located in the southwest region of
the United States. Our planned expansion into geographic areas outside the
Southwest involves a number of risks, including:
 
   
    - uncertainties related to local demographics, tastes and preferences;
    
 
   
    - local custom, wages, costs and other legal and economic conditions
      particular to new regions;
    
 
    - the need to develop relationships with local distributors and suppliers
      for fresh produce, fresh tortillas and other ingredients;
 
    - potential difficulties related to management of operations located in a
      number of broadly dispersed locations; and
 
   
    - lack of market awareness or acceptance of our restaurant concept in new
      geographic areas.
    
 
   
    We may not be successful in addressing these risks. We also may not be able
to open our planned new operations on a timely basis, or at all in these new
areas. Delays in opening or failure to open planned new restaurants outside the
Southwest could have a material adverse effect on our business and results of
operations. We currently anticipate that our new restaurants will take several
months to reach planned operating levels due to inefficiencies typically
associated with expanding into new regions, such as lack of market awareness,
acceptance of our restaurant concept and inability to hire sufficient staff.
    
 
   
    IF WE ARE NOT ABLE TO SUCCESSFULLY PURSUE OUR RAPID EXPANSION STRATEGY, OUR
BUSINESS AND RESULTS OF OPERATIONS MAY BE ADVERSELY IMPACTED.
    
 
   
    We intend to continue to pursue a rapid expansion strategy. Since 1996, we
have opened 36 restaurants, 12 of which were opened outside of Southern
California. We intend to open an additional 28 restaurants in 1999, eight of
which have been opened to date. Approximately 13 of those additional restaurants
are outside Southern California. We intend to open an additional 36 restaurants
in 2000. Our ability to successfully achieve our expansion strategy will depend
on a variety of factors, many of which are beyond our control. These factors
include:
    
 
    - our ability to locate suitable restaurant sites or negotiate acceptable
      lease terms;
 
    - our ability to obtain required local, state and federal governmental
      approvals and permits related to construction of the sites, food and
      alcoholic beverages;
 
    - our dependence on contractors to construct new restaurants in a timely
      manner;
 
    - our ability to attract, train and retain qualified and experienced
      restaurant personnel and management;
 
    - our ability to operate our restaurants profitably;
 
    - our need for additional capital and our ability to obtain such capital on
      favorable terms or at all;
 
    - our ability to respond effectively to the intense competition in the
      quick-service restaurant industry; and
 
    - general economic conditions.
 
                                       7
<PAGE>
   
    If we are not able to successfully address these factors, we may not be able
to expand at a rate currently contemplated by our strategy, and our business and
results of operations may be adversely impacted.
    
 
   
    OUR OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY DUE TO SEASONALITY AND
OTHER FACTORS, WHICH COULD HAVE A NEGATIVE EFFECT ON THE PRICE OF OUR COMMON
STOCK.
    
 
   
    Our business is subject to seasonal fluctuations. Historically, sales in
most of our restaurants have been higher during the second and third quarters of
each fiscal year. As a result, we expect our highest earnings to occur in the
second and third quarters of each fiscal year.
    
 
   
    In addition to seasonality, our quarterly and annual operating results and
comparable unit sales may fluctuate significantly as a result of a variety of
factors, including:
    
 
    - labor costs for our hourly and management personnel, including increases
      in federal or state minimum wage requirements;
 
    - fluctuations in food costs, particularly the cost of chicken, beef, fish,
      cheese and produce;
 
    - the timing of new restaurant openings and related expenses;
 
    - the amount of sales contributed by new and existing restaurants;
 
    - our ability to achieve and sustain profitability on a quarterly or annual
      basis;
 
    - consumer confidence;
 
    - changes in consumer preferences;
 
    - the level of competition from existing or new competitors in the
      quick-service restaurant industry;
 
    - factors associated with closing a unit, including payment of the base rent
      for the balance of the lease term;
 
    - impact of weather on revenues and costs of food; and
 
    - general economic conditions.
 
   
    Accordingly, results for any one quarter are not necessarily indicative of
results to be expected for any other quarter or for any year. Comparable unit
sales for any particular future period may decrease. Please see "Management's
Discussion and Analysis of Financial Condition and Results of Operations" for a
discussion of factors which have historically affected our operating results.
    
 
    THE RESTAURANT INDUSTRY IS INTENSELY COMPETITIVE AND WE MAY NOT HAVE THE
RESOURCES TO COMPETE ADEQUATELY.
 
    The restaurant industry is intensely competitive. There are many different
segments within the restaurant industry that are distinguished by types of
service, food types and price/value relationships. We position our restaurants
in the high-quality, quick-service Mexican food segment of the industry. In this
segment, our direct competitors include Baja Fresh, La Salsa and Chipotle. We
also compete indirectly with full-service Mexican restaurants including Chevy's,
Chi Chi's and El Torito, and fast food restaurants, particularly those focused
on Mexican food such as Taco Bell and Del Taco. Competition in our industry
segment is based primarily upon food quality, price, restaurant ambiance,
service and location. Although we believe we compete favorably with respect to
each of these factors, many of our direct and indirect competitors are
well-established national, regional or local chains and have substantially
greater financial, marketing, personnel and other resources than we do. We also
compete with many other retail establishments for site locations.
 
    The performance of individual units may also be affected by factors such as
traffic patterns, demographic considerations and the type, number and proximity
of competing restaurants. In addition, factors such as inflation, increased
food, labor and employee benefit costs and the availability of experienced
management and hourly employees may also adversely affect the restaurant
industry in general and our units in particular.
 
                                       8
<PAGE>
   
    THE ABILITY TO ATTRACT AND RETAIN HIGHLY QUALIFIED PERSONNEL TO OPERATE AND
MANAGE OUR RESTAURANTS IS EXTREMELY IMPORTANT AND OUR FAILURE TO DO SO COULD
ADVERSELY AFFECT US.
    
 
   
    Our success and the success of our individual restaurants depend upon our
ability to attract and retain highly motivated, well-qualified restaurant
operators and other management personnel, as well as a sufficient number of
qualified employees, including guest service and kitchen staff, to keep pace
with our expansion schedule. Qualified individuals needed to fill these
positions are in short supply in some geographic areas. Our inability to recruit
and retain such individuals may delay the planned openings of new restaurants or
result in higher employee turnover in existing restaurants, which could have a
material adverse effect on our business or results of operations. We also face
significant competition in the recruitment of qualified employees. In addition,
we are heavily dependent upon the services of our officers and key management
involved in restaurant operations, marketing, finance, purchasing, expansion,
human resources and administration. The loss of any of these individuals could
have a material adverse effect on our business and results of operations. We
currently do not have employment agreements with any of our employees.
    
 
   
    OUR RESOURCES MAY BE STRAINED IN IMPLEMENTING OUR BUSINESS STRATEGY.
    
 
    Our growth strategy will place a strain on our management, financial and
other resources. To manage our growth effectively, we must maintain the level of
quality and service at our existing and future restaurants. We must also
continue to enhance our operational, financial and management systems and
locate, hire, train and retain experienced and dedicated operating personnel,
particularly managers. We may not be able to effectively manage any one or more
of these or other aspects of our expansion. Failure to do so could have a
material adverse effect on our business and results of operations.
 
   
    WE MAY BE UNABLE TO FUND OUR SUBSTANTIAL WORKING CAPITAL REQUIREMENTS AND
MAY NEED ADDITIONAL FUNDING SOONER THAN WE ANTICIPATE.
    
 
    We believe that the proceeds from this offering, together with anticipated
cash flow from operations and funds anticipated to be available from a credit
facility, will be sufficient to satisfy our working capital requirements for at
least the next 12 months. We plan to incur substantial costs over the near-term
in connection with our expansion plans. We may need to seek additional financing
sooner than we anticipate as a result of the following factors:
 
    - changes in our operating plans;
 
    - acceleration of our expansion plans;
 
    - lower than anticipated sales of our menu offerings;
 
    - increased food and/or labor costs; and
 
    - potential acquisitions.
 
   
    Additional financing may not be available on acceptable terms, or at all. If
we fail to get additional financing as needed, our business and results of
operations would likely suffer. Please see "Management's Discussion and Analysis
of Financial Condition and Results of Operations" for a discussion of our
expected capital needs and current resources available.

<PAGE>
   
    UNANTICIPATED COSTS OR DELAYS IN THE DEVELOPMENT OR CONSTRUCTION OF OUR
RESTAURANTS COULD PREVENT OUR TIMELY AND COST-EFFECTIVE OPENING OF NEW
RESTAURANTS.
    
 
    We depend on contractors and real estate developers to construct our
restaurants. Many factors may adversely affect the cost and time associated with
the development and construction of our restaurants, including:
 
    - labor disputes;
 
    - shortages of materials and skilled labor;
 
    - adverse weather;
 
    - unforeseen engineering problems;
 
    - environmental problems;
 
    - construction or zoning problems;
 
    - local government regulations;
 
    - modifications in design; and
 
    - other unanticipated increases in costs.
 
    Any of these factors could give rise to delays or cost overruns which may
prevent us from developing additional restaurants within our anticipated budgets
or time periods. Any such failure could have a material adverse effect on our
business and results of operations.
 
   
    OUR RESTAURANTS ARE CONCENTRATED IN THE SOUTHWEST REGION OF THE UNITED
STATES, AND THEREFORE, OUR BUSINESS IS SUBJECT TO FLUCTUATIONS IF ADVERSE
BUSINESS CONDITIONS OCCUR IN THAT REGION.
    
 
   
    All but two of our existing restaurants are located in the southwest region
of the United States. Accordingly, we are susceptible to fluctuations in our
business caused by adverse economic or other conditions in this region,
including natural or other disasters. Our significant investment in, and
long-term commitment to, each of our units limits our ability to respond quickly
or effectively to changes in local competitive conditions or other changes that
could affect our operations. In addition, some of our competitors have many more
units than we do. Consequently, adverse economic or other conditions in a
region, a decline in the profitability of several existing units or the
introduction of several unsuccessful new units in a geographic area could have a
more significant effect on our results of operations than would be the case for
a company with a larger number of restaurants or with more geographically
dispersed restaurants.
    
 
    OUR FAILURE OR INABILITY TO ENFORCE OUR TRADEMARKS AND TRADE NAMES COULD
ADVERSELY AFFECT OUR EFFORTS TO ESTABLISH BRAND EQUITY.
 
    Our ability to successfully expand our concept will depend on our ability to
establish and maintain "brand equity" through the use of our trademarks, service
marks, trade dress and other proprietary intellectual property, including our
name and logos. We currently hold three trademarks and have seven service marks
relating to our brand. Some or all of the rights in our intellectual property
may not be enforceable, even if registered, against any prior users of similar
intellectual property or our competitors who seek to utilize similar
intellectual property in areas where we operate or intend to conduct operations.
If we fail to enforce any of our intellectual property rights, we may be unable
to capitalize on our efforts to establish brand equity. It is also possible that
we will encounter claims from prior users of similar intellectual property in
areas where we operate or intend to conduct operations. Claims from prior users
could limit our operations and possibly cause us to pay damages or licensing
fees to a prior user or registrant of similar intellectual property.
 
                                       10
<PAGE>
   
    IF WE ARE NOT ABLE TO ANTICIPATE AND REACT TO OUR FOOD AND LABOR COSTS, WE
COULD BE ADVERSELY AFFECTED.
    
 
   
    Our restaurant operating costs principally consist of food and labor costs.
Our profitability is dependent on our ability to anticipate and react to changes
in food and labor costs. Various factors beyond our control, including adverse
weather conditions and governmental regulation, may affect our food costs. We
may not be able to anticipate and react to changing food costs, whether through
our purchasing practices, menu composition or menu price adjustments in the
future. In the event that food or labor price increases cause us to increase our
menu prices, we face the risk that our guests will choose to patronize
lower-cost restaurants. Failure to react to changing food costs or to retain
guests if we are forced to raise menu prices could have a material adverse
effect on our business and results of operations. For more information regarding
our food supply sources and buying practices, please see "Business--Purchasing."
    
 
   
    A substantial number of our employees are subject to various minimum wage
requirements. Many of our employees work in restaurants located in California
and receive salaries equal to or slightly greater than the California minimum
wage. Effective March 1, 1998, the minimum wage in California increased to $5.75
per hour from $5.15. Similar proposals may come before legislators or voters in
other jurisdictions in which we operate or seek to operate. Such minimum wage
increases could have a material adverse effect on our business and results of
operations. Please see "Business--Operations" for more information on the number
of and the benefits we provide to our employees.
    
 
    AS A RESTAURANT SERVICE PROVIDER, WE COULD BE SUBJECT TO ADVERSE PUBLICITY
OR CLAIMS FROM OUR GUESTS.
 
   
    We may be the subject of complaints or litigation from guests alleging
food-related illness, injuries suffered on the premises or other food quality,
health or operational concerns. Adverse publicity resulting from such
allegations may materially adversely affect us and our restaurants, regardless
of whether such allegations are true or whether we are ultimately held liable.
We may also be the subject of complaints or allegations from current, former or
prospective employees from time to time. A lawsuit or claim could result in an
adverse decision against us that could have a material adverse effect on our
business and results of operations.
    
 
   
    WE MAY NOT BE ABLE TO OBTAIN AND MAINTAIN STATE AND LOCAL PERMITS NECESSARY
TO OPERATE OUR UNITS.
    
 
   
    The failure to maintain necessary licenses, permits or approvals, including
food and alcoholic beverage licenses, or to comply with other government
regulations could have a material adverse effect on our business and results of
operations. In addition, difficulties or failures in obtaining required licenses
and approvals will result in delays in, or cancellation of, the opening of new
units. Restaurants are subject to licensing and regulation by state and local
health, environmental, labor relations, sanitation, building, zoning, safety,
fire and other departments. Our activities are also subject to the Federal
Americans With Disabilities Act and related regulations, which prohibit
discrimination on the basis of disability in public accommodations and
employment. We are also subject to state "dram-shop" laws and regulations, which
generally provide that a person injured by an intoxicated person may seek to
recover damages from an establishment that wrongfully served alcoholic beverages
to such person. Given the location of many of our restaurants, even if our
operation of those restaurants is in strict compliance with the requirements of
the Immigration and Naturalization Service, our employees may not all meet
federal citizenship or residency requirements, which could lead to disruptions
in our work force. If we are not in compliance with these requirements, we could
be subject to financial penalties. In addition, we could be forced to terminate
employees who do not meet these requirements. These consequences could adversely
affect our business. The development and construction of additional units will
also be subject to compliance with applicable zoning, land use and environmental
regulations. There can be no assurance that we will be able to obtain necessary
variances or other approvals on a cost-effective and timely basis in order to
construct and develop units in the future. Changes in any or all of these laws
or regulations, such as government-imposed paid leaves of absence or mandated
health benefits, could have a material adverse effect on our business and
results of operations. For a more complete description of the governmental
regulations to which our business is subject, please see "Business--Government
Regulation."

<PAGE>
   
    OUR CURRENT INSURANCE MAY NOT PROVIDE ADEQUATE LEVELS OF COVERAGE AGAINST
CLAIMS.
    
 
   
    There are types of losses we may incur that may be uninsurable or that we
believe are not economically insurable, such as losses due to earthquakes and
other natural disasters. In view of the location of many of our existing and
planned units, our operations are particularly susceptible to damage and
disruption caused by earthquakes. In the event of an earthquake or other natural
disaster affecting the geographic area of our operations, we could suffer a loss
of the capital invested in, as well as anticipated earnings from, the damaged or
destroyed properties. Further, we do not currently maintain any insurance
coverage for employee-related litigation or the effects of adverse publicity. In
addition, punitive damage awards are generally not covered by insurance. We may
also be subject to litigation which, regardless of the outcome, could result in
adverse publicity and damages. Such litigation, adverse publicity or damages
could have a material adverse effect on our business and results of operations.
    
 
   
    WE MAY FAIL TO BE YEAR 2000 COMPLIANT.
    
 
    We have not fully completed tests to assure that our systems will function
properly in the year 2000. Our restaurant information systems may need to be
upgraded in order to prevent system failure or miscalculation resulting from the
year 2000 that could disrupt our normal business activities.
 
    We estimate that we have incurred costs of less than $25,000 to date in
connection with our year 2000 plan. We currently estimate the total costs of
completing our year 2000 plan, including costs incurred to date, to be less than
$50,000. Until our testing is complete and our vendors and providers are
contacted, we will not be able to completely evaluate whether our information
technology systems or non-information technology systems will need to be revised
or replaced. If our efforts to address year 2000 risks are not successful, or if
suppliers or other third parties with whom we conduct business do not
successfully address such risks, it could have a material adverse effect on our
business and results of operations. Please see "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000 Readiness
Disclosure" for detailed information on our state of readiness, potential risks
and contingency plans regarding the year 2000 issue.
 
   
    IF WE ADOPT A FRANCHISING STRATEGY, WE MAY BE UNSUCCESSFUL IN EXECUTING A
FRANCHISING PROGRAM.
    
 
   
    We may use a franchise strategy in selected markets. If we adopt a
franchising strategy, our failure to successfully execute a franchising program
could adversely affect our business and results of operations. We have not used
franchising to date and may not be successful in implementing a franchise
program in the future. We have not yet established any criteria to evaluate
prospective franchisees. We may be unable to identify and attract franchisees
that have the business abilities or access to financial resources necessary to
open our restaurants, or to successfully develop or operate our restaurants in
their franchise areas in a manner consistent with our standards.
    
 
RISKS RELATED TO THIS OFFERING
 
    THE LARGE NUMBER OF SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING
COULD CAUSE OUR STOCK PRICE TO DECLINE.
 
    The market price of our common stock could decline as a result of sales by
our existing stockholders of a large number of shares of our common stock in the
market after this offering or the perception that such sales could occur. These
sales also might make it more difficult for us to sell equity securities in the
future at a time and at a price that we deem appropriate. Please see "Shares
Eligible for Future Sale" for a description of sales that may occur in the
future.

<PAGE>
   
    OUR COMMON STOCK MAY NOT DEVELOP AN ACTIVE, LIQUID TRADING MARKET.
    
 
   
    We cannot predict the extent to which investor interest in us will lead to
the development of an active trading market or the level of trading volume that
will exist for our common stock after the offering. Low trading volumes may
adversely affect your ability to sell your shares quickly at the current market
price. The initial public offering price for the shares will be determined by
negotiations among us, the selling stockholders and the representatives of the
underwriters. This initial price may not be indicative of prices that will
prevail in the trading market. Please see "Underwriting" for more information
regarding our arrangement with the underwriters and the factors considered in
setting the initial public offering price.
    
 
    THE MARKET PRICE OF OUR STOCK MAY BE ADVERSELY AFFECTED BY MARKET
     VOLATILITY.
 
    The stock market has experienced extreme price and volume fluctuations. The
trading price of our common stock could be subject to wide fluctuations in
response to a number of factors, including:
 
    - fluctuations in our quarterly or annual results of operations;
 
    - changes in published earnings estimates by analysts and whether our
      earnings meet or exceed such estimates;
 
    - additions or departures of key personnel; and
 
    - changes in overall stock market conditions, including the stock prices of
      other restaurant companies.
 
    In the past, companies that have experienced volatility in the market price
of their stock have been the object of securities class action litigation. If we
were subject to securities class action litigation, it could result in
substantial costs and a diversion of our management's attention and resources.
 
    THE INTERESTS OF OUR CONTROLLING STOCKHOLDERS MAY CONFLICT WITH YOUR
     INTERESTS.
 
   
    We anticipate that the executive officers, directors and entities affiliated
with them will, in the aggregate, beneficially own approximately 55.0% of our
outstanding common stock following the completion of this offering. These
stockholders will be able to exercise control over all matters requiring
approval by our stockholders, including the election of directors and approval
of significant corporate transactions. This concentration of ownership may also
have the effect of delaying or preventing a change in control of our company.
Please see "Management" and "Principal Stockholders" for detailed information on
the beneficial ownership of our executive officers, directors and their
affiliates.
    
 
    ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD
MAKE A THIRD-PARTY ACQUISITION OF US DIFFICULT.
 
   
    The anti-takeover provisions in our certificate of incorporation, our bylaws
and Delaware law could make it more difficult for a third party to acquire us.
As a result of these provisions, we could delay, deter or prevent a takeover
attempt or third party acquisition that our stockholders consider to be in their
best interest, including a takeover attempt that results in a premium over the
market price for the shares held by our stockholders. Please see "Description of
Securities" for more information on these anti-takeover provisions.
    
 
   
                           FORWARD-LOOKING STATEMENTS
    
 
   
    This prospectus may contain forward-looking statements based on our current
expectations, assumptions, estimates and projections about us and our industry.
These forward-looking statements involve risks and uncertainties. Our actual
results could differ materially from those anticipated in these forward-looking
statements as a result of factors more fully described in the "Risk Factors"
section and elsewhere in this prospectus. We are not obligated to update or
revise these forward-looking statements to reflect new events or circumstances.

                                USE OF PROCEEDS
 
    We estimate that the net proceeds from the sale of the 2,250,000 shares
offered by us will be approximately $20.2 million, assuming an initial public
offering price of $10.00 per share and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable
by us. If our portion of the underwriters' over-allotment option is exercised in
full, we estimate that such net proceeds will be approximately $22.0 million.
 
   
    We intend to use approximately $18.0 million of the net proceeds of this
offering for development of new restaurants, approximately $1.7 million for
repayment of term loan debt and the remainder for working capital and other
general corporate purposes. Our term loan agreement with BankBoston, N.A. was
amended on April 1, 1999, and now bears interest at the lesser of (1) the London
InterBank Offered Rate, also known as LIBOR, adjusted by the statutory reserve
rate plus 3.0%, or (2) the greater of the bank's base rate plus 0.75% or the
Federal Funds Effective Rate plus 1.5%. Pending any such use, as described
above, we intend to invest the net proceeds in interest-bearing instruments. We
will not receive any proceeds from the sale of shares by the selling
stockholders. Please see "Selling Stockholders" for a description of the number
of shares which may be sold by selling stockholders in this offering.
    
 
                                DIVIDEND POLICY
 
    We have never declared or paid any cash dividends on our capital stock. Our
term loan agreement with BankBoston requires us to obtain the bank's consent
prior to making any distribution or declaring any dividends. We do not expect to
pay any cash dividends for the foreseeable future. We currently intend to retain
future earnings, if any, to finance the expansion of our business. Any future
determination to pay cash dividends will be at the discretion of our board of
directors and will be dependent on financial condition, operating results,
capital requirements and other factors that our board deems relevant.

                                    DILUTION
 
   
    Our net tangible book value as of March 28, 1999, after giving effect to the
automatic conversion of all outstanding shares of preferred stock into common
stock, was $17,922,782, or $2.82 per share of common stock. Net tangible book
value per share is equal to the amount of our total tangible assets less total
liabilities, divided by the number of shares of common stock outstanding as of
March 28, 1999. Assuming the sale by us of the 2,250,000 shares offered at an
assumed initial public offering price of $10.00 per share and after deducting
underwriting discounts and estimated offering expenses, and the application of
the estimated net proceeds therefrom, our pro forma net tangible book value as
of March 28, 1999 would have been $38,147,782, or $4.43 per share of common
stock. This represents an immediate increase in net tangible book value of $1.61
per share to existing stockholders and an immediate dilution in pro forma net
tangible book value of $5.57 per share to new investors. The following table
illustrates this per share dilution:

    The tables and calculations above assume no exercise of outstanding options
or warrants unless otherwise set forth in this prospectus. On March 28, 1999,
there were:
    
 
   
    - 379,376 shares issuable upon the exercise of options outstanding at a
      weighted average exercise price of $3.89 per share;
    
 
   
    - 45,000 shares issuable upon the exercise of an outstanding warrant at an
      exercise price of $7.20 per share; and
    
 
   
    - 244,562 shares available for issuance under our stock option plans. Since
      March 28, 1999, we have granted options exercisable into 192,000 shares at
      a weighted average exercise price of $10.00 per share.
    
 
   
    To the extent that these options or warrants are exercised, there will be
further dilution to new investors. Please see "Management--Benefit Plans" for a

December 27, 1998, and the consolidated balance sheet data at December 28, 1997
and December 27, 1998 are derived from our consolidated financial statements
which have been audited by Deloitte & Touche LLP, independent auditors, and are
included elsewhere in this prospectus. The statement of operations data for the
two years ended December 31, 1994 and 1995, and the consolidated balance sheet
data at December 31, 1994 and 1995 and December 29, 1996 are derived from
audited consolidated financial statements not included in this prospectus. The
consolidated statement of operations data for the three months ended March 29,
1998 and March 28, 1999 and the consolidated balance sheet data at March 28,
1999 have been derived from the unaudited financial statements included
elsewhere in this prospectus that have been prepared on the same basis as the
audited consolidated financial statements and, in our opinion, contain all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the financial position and results of operations for such
periods. Historical results are not necessarily indicative of the results to be
expected in the future and results for interim periods are not necessarily
indicative of results for the entire year.

    Please see the consolidated financial statements and related notes appearing
elsewhere in this prospectus for the determination of number of shares used in
computing basic and diluted net income (loss) per share.
    
 
   
    Net income (loss) attributable to common stockholders includes the effect of
the accretion on the redeemable convertible preferred stock which reduces net
income (loss) attributable to common stockholders for the related periods. Net
income attributable to common stockholders for the fiscal 1998 diluted earnings
per share calculation is $915,000. The difference from the basic calculation is
due to the reversal of the accretion on the redeemable convertible preferred
stock as such stock is assumed to be converted to common stock for purposes of
the diluted calculation.
    
 
   
    Net income for fiscal year 1998 was favorably impacted by the reversal of a
$452,000 deferred tax asset allowance that was previously provided for in fiscal
year 1997. We eliminated the valuation allowance in 1998 due to our belief that
current year activity made realization of such benefit more likely than not.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS SHOULD BE READ IN CONJUNCTION WITH OUR CONSOLIDATED FINANCIAL
STATEMENTS AND NOTES APPEARING ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
   
    We own and operate 67 high-quality, quick-service Mexican restaurants under
the name "Rubio's Baja Grill." In addition, we license our concept to other
restaurant operators in three non-traditional locations at Qualcomm Stadium, the
San Diego International Airport food court and the Del Mar Thoroughbred Club. We
opened our first restaurant in 1983, and grew steadily through 1994, at which
time we operated 17 units. We increased the number of restaurant openings in
recent years, opening six in 1995, eight in 1996, 12 in 1997 and 16 in 1998. We
intend to open 28 units in 1999, of which eight have been opened to date, and 36
units in 2000.
    
 
    As a result of our rapid expansion, period to period comparisons of our
financial results may not be meaningful. When a new unit opens, it will
typically incur higher than normal levels of food and labor costs until new
personnel gain experience. Hourly labor schedules are gradually adjusted
downward during the first three months of a restaurant opening, in order to
reach operating efficiencies similar to those at established units. In
calculating comparable restaurant sales, we introduce a restaurant into our
comparable restaurant base once it has been in operation for 15 calendar months.
 
   
    Throughout our history, we have sought to evolve our concept and menu in
order to meet the changing needs and taste preferences of our guests. From
January through April 1997, we modified our restaurant concept to include a
broader menu selection and updated our restaurant decor. To reflect these
additions and improvements in our concept, we changed our name to "Rubio's Baja
Grill, Home of the Fish Taco" from "Rubio's, Home of the Fish Taco." During this
time we added and deleted various menu items, upgraded other menu items and
increased prices on selected items. We believe that this concept modification
was a critical factor influencing the comparable restaurant sales increases of
18.0% reported in 1997 and 10.4% reported in 1998. Since the spring of 1997, our
sales and costs reflect these higher quality, higher cost and higher priced menu
items and may not be comparable to historical comparable period results.
    
 
   
    In conjunction with the modification of our restaurant concept, we increased
our marketing expenditures from $515,000 in 1996 to $1.1 million in 1997 and
$1.4 million in 1998. In particular, we increased media spending and, we
believe, used this medium more efficiently to augment growth in our sales base.
We believe our restaurant sales are favorably impacted by radio and television
advertising and that this advertising helped to contribute to the comparable
restaurant sales increases in both 1997 and 1998.
    
 
    Sales represents gross sales less sales taxes, coupons and other discounts.
Cost of sales is composed of food, beverage and paper supply expenses.
Components of restaurant labor, occupancy and other expenses include direct
hourly and management wages, bonuses, fringe benefit costs, rent and other
occupancy costs, advertising and promotion, operating supplies, utilities,
maintenance and repairs and other operating expenses.
 
    General and administrative expenses include all corporate and administrative
functions that support existing operations and provide infrastructure to
facilitate our future growth. Components of this category include management,
supervisory and staff salaries and employee benefits, travel, information
systems, training, corporate rent and professional and consulting fees.

    Pre-opening costs, which are expensed as incurred, consist of the costs of
hiring and training the initial workforce, travel, the cost of food used in
training, the cost of the initial stocking of operating supplies and other
direct costs related to the opening.
    
 
    We have leased all of our facilities, except for one building, in order to
minimize the cash investment associated with each unit. The majority of our
leases are for 10-year terms and include options to extend the terms. The
majority of our leases also include both fixed rate and percentage-of-sales rent
provisions.
 
   
    We use a 52- or 53-week fiscal year ending on the Sunday nearest December
31. Fiscal years 1996, 1997 and 1998 each consisted of 52 weeks. The three-month
periods ended March 29, 1998 and March 28, 1999 each consisted of 13 weeks.
    
 
RESULTS OF OPERATIONS
 
    Our operating results, expressed as a percentage of sales, were as follows:

    QUARTER ENDED MARCH 28, 1999 COMPARED TO THE QUARTER ENDED MARCH 29, 1998
    
 
   
    Results of operations reflect a full quarter of operations for 59
restaurants and 43 restaurants for the quarters ended March 28, 1999 and March
29, 1998, respectively. Results of operations also reflect a partial quarter of
operations for five and three restaurants for the quarters ended March 28, 1999
and March 29, 1998, respectively.
    
 
   
    SALES.  Sales increased $5.2 million, or 56.5%, to $14.4 million in the
first quarter of 1999 from $9.2 million in the first quarter of 1998. This
increase was principally due to the realization of a full quarter of operations
from the 16 units opened in 1998 resulting in sales of $3.5 million in the first
quarter of 1999 and $608,000 in sales derived from the five units opened in
1999, along with a comparable unit sales increase of $1.1 million, or 13.7%. The
comparable unit sales increase was driven by the success of a 99-cent fish taco
radio promotion in the first quarter of 1999, combined with slightly
    
 
                                       19
<PAGE>
   
weaker sales in 1998 as a result of poor weather related to El Nino. We also
introduced a price increase of approximately 1.5% at the beginning of 1999.
    
 
   
    COST OF SALES.  Cost of sales as a percentage of sales increased to 29.5% in
1999 from 29.0% in 1998 primarily due to increases in the cost of food items.
    
 
   
    RESTAURANT LABOR, OCCUPANCY AND OTHER.  Restaurant labor, occupancy and
other decreased as a percentage of sales to 50.4% in 1999 from 53.1% in 1998.
This reduction was due primarily to lower labor, minimum rent and other fixed
unit operating expenses as a result of the efficiencies associated with
increased unit sales.
    
 
   
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $2.1 million in the first quarter of 1999 from $1.4 million in the
first quarter of 1998. The increase is principally due to $182,000 in accrued
executive bonus expense resulting from our strong first quarter performance,
$131,000 in salaries and benefits related to the hiring of additional corporate
employees and field management personnel required to support and manage unit
expansion, $93,000 in management recruiting costs, and $242,000 in other
corporate level expenses related to our business growth. General and
administrative expenses decreased as a percentage of sales to 14.4% in the first
quarter of 1999 from 15.5% in the first quarter of 1998 primarily due to our
expanding revenue base.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$641,000 in the first quarter of 1999 from $426,000 in 1998. The increase was
primarily due to the additional depreciation on the new units opened during 1998
and during the first quarter of 1999.
    
 
   
    PRE-OPENING EXPENSES.  Pre-opening expenses increased to $94,000 in the
first quarter of 1999 from $51,000 in the first quarter of 1998 primarily due to
the increase in unit openings to five in the first quarter of 1999 compared to
three in the first quarter of 1998.
    
 
   
    INTEREST INCOME (EXPENSE), NET.  Net interest income decreased to $7,000 in
the first quarter of 1999 from $79,000 in net interest income in the first
quarter of 1998. This decrease is primarily due to a decrease in cash available
for investing, which resulted in a decline of interest income to $63,000 in the
first quarter of 1999 from $137,000 in the first quarter of 1998. The decrease
in cash available to generate interest income resulted from the use of these
funds for the development of new restaurants.
    
 
   
    INCOME TAXES.  The provision for income taxes in the first quarter of 1999
and 1998 is based on the annual effective tax rate applied to the respective
quarter's pretax book income (loss). The 40% tax rate applied in the first
quarter of 1999 comprises the federal and state statutory rates based on the
estimated annual effective rate for 1999. The 7.8% tax rate applied in the first
quarter of 1998 is primarily a result of the recognition of 1997 net deferred
tax assets previously valued, due to fiscal 1998 net income and the future
realizability of such net deferred tax assets.
    
 
    YEAR ENDED DECEMBER 27, 1998 COMPARED TO YEAR ENDED DECEMBER 28, 1997
 
    Results of operations reflect a full year of operations of 43 restaurants
and 31 restaurants for the years ended December 27, 1998 and December 28, 1997,
respectively. Results of operations also reflect partial year of operations of
16 restaurants and 12 restaurants for the years ended December 27, 1998 and
December 28, 1997, respectively.
 
   
    SALES.  Sales increased $15.0 million, or 50.5%, to $44.7 million in 1998
from $29.7 million in 1997. This increase was principally due to $6.4 million in
sales generated by a full year of operations from 12 units opened in 1997 and
$5.7 million in sales derived from the 16 units opened in 1998, along with a
comparable unit sales increase of $2.8 million, or 10.4%. The comparable unit
sales increase was driven both by the momentum generated by the Baja Grill
concept, as well as the success of the lobster
    
 
                                       20

burrito promotion, which took place from June through September 1998. We also
introduced a price increase of approximately 1.5% at the beginning of 1998.
 
    COST OF SALES.  Cost of sales as a percentage of sales remained constant at
29.2% in 1998 and 1997.
 
   
    RESTAURANT LABOR, OCCUPANCY AND OTHER.  Restaurant labor, occupancy and
other decreased as a percentage of sales to 50.6% in 1998 from 52.6% in 1997.
This reduction was due primarily to lower labor, minimum rent and other fixed
unit operating expenses as a percentage of sales as a result of the efficiencies
associated with increased unit sales. In addition, there were non-recurring
expenses incurred in 1997, related to the modification of our restaurant
concept. These one-time expenses included higher levels of hourly employee
training and operating supplies, resulting in higher 1997 total expenses in this
category.
    
 
   
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $6.1 million in 1998 from $4.3 million in 1997, primarily due to
$1.0 million in salary and benefits related to the hiring of additional
corporate employees and field management required to support and manage unit
expansion, $296,000 related to a senior management bonus expense incurred in
1998 which was not incurred in 1997, and $586,000 in other corporate level
expenses related to our business growth. General and administrative expenses
decreased as a percentage of sales to 13.8% in 1998 from 14.3% in 1997 primarily
due to our expanding revenue base.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$1.9 million in 1998 from $1.3 million in 1997. The increase was primarily due
to the additional depreciation on the 16 new units opened during 1998.
    
 
    PRE-OPENING EXPENSES.  Pre-opening expenses increased to $319,000 in 1998
from $271,000 in 1997 primarily due to the increase in unit openings in 1998 to
16 from 12 in the prior period.
 
    LOSS ON ASSET IMPAIRMENT.  There was no loss on asset impairment in 1998.
Loss on asset impairment of $387,000 in 1997 reflects the difference between the
carrying value and the estimated fair value of the assets of one restaurant
location.
 
    INTEREST INCOME (EXPENSE), NET.  Net interest income increased to $268,000
in 1998 from $75,000 in net interest expense in 1997. This increase was
primarily due to an increase in interest income from $188,000 in 1997 to
$521,000 in 1998 resulting from interest and other investment income associated
with the investment of the net proceeds from our $10.1 million preferred stock
private placement in November 1997.
 
    INCOME TAXES.  The provision (benefit) for income taxes in 1998 and 1997 is
based on the approximate tax rate applied to the respective year's pre-tax book
income (loss). The 7.8% tax benefit applied in 1998 is primarily a result of the
recognition of prior year net deferred tax assets previously valued, due to the
current year net income and the future realizability of such net deferred tax
assets.
 
    YEAR ENDED DECEMBER 28, 1997 COMPARED TO YEAR ENDED DECEMBER 29, 1996
 
   
    Results of operations reflect a full year of operations of 31 restaurants
and 23 restaurants for the years ended December 28, 1997 and December 29, 1996,
respectively. Results of operations also reflect a partial year of operations of
12 restaurants and eight restaurants for the years ended December 28, 1997 and
December 29, 1996, respectively.
    
 
   
    SALES.  Sales increased $10.2 million, or 52.1%, to $29.7 million in 1997
from $19.5 million in 1996. This increase was principally due to $3.1 million in
sales generated by a full year of operations from eight units opened in 1996 and
$3.9 million in sales derived from the 12 units opened in 1997, along
    
 
                                       21
<PAGE>
   
with a comparable unit sales increase of $3.2 million or 18.0% driven primarily
by the modification to the Baja Grill concept and related promotional campaigns.
    
 
    COST OF SALES.  Cost of sales as a percentage of sales increased to 29.2% in
1997 from 26.0% in 1996, primarily due to the modification to the Baja Grill
concept. The new menu items offered with the Baja Grill menu, particularly those
containing chargrilled chicken and steak, reflect higher food cost percentages
than items replaced or retained from the previous menu.
 
    RESTAURANT LABOR, OCCUPANCY AND OTHER.  Restaurant labor, occupancy and
other decreased as a percentage of sales to 52.6% in 1997 from 53.5% in 1996.
This reduction was due primarily to a decrease in unit minimum rent as a
percentage of sales resulting from our expanding revenue base.
 
   
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $4.3 million in 1997 from $3.2 million in 1996, primarily due to
$697,000 in salaries and benefits related to the hiring of additional corporate
employees and field management personnel required to support and manage unit
expansion and $384,000 in other corporate level expenses related to our business
growth. General and administrative expenses decreased as a percentage of sales
to 14.3% in 1997 from 16.3% in 1996 due primarily to our expanding revenue base.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$1.3 million in 1997 from $735,000 in 1996. This $524,000 increase was primarily
due to the additional depreciation on the 12 new units opened during 1997 as
well as the depreciation of the fixed assets purchased in conjunction with the
modification to the Baja Grill concept.
    
 
    PRE-OPENING EXPENSES.  Pre-opening expenses increased to $271,000 in 1997
from $18,000 in 1996 primarily due to the increase in unit openings in 1997 to
12 from eight in the prior period. Prior to the third quarter of 1996, we did
not report pre-opening expenses separately from recurring restaurant expense
categories on our income statement.
 
    LOSS ON ASSET IMPAIRMENT.  Loss on asset impairment of $387,000 in 1997
reflects the difference between the carrying value and the estimated fair value
of the assets of one restaurant location.
 
   
    GAIN (LOSS) ON DISPOSAL/SALE OF PROPERTY.  The $56,000 loss on the sale of
property in 1997 resulted primarily from the disposal of assets in conjunction
with the modification of units to the Baja Grill concept.
    
 
    INTEREST INCOME (EXPENSE), NET.  Net interest expense increased to $75,000
in 1997 from $17,000 in net interest income in 1996. This decrease was primarily
due to less cash invested in short-term instruments. This net reduction in
interest was offset by an increase in borrowing related to the new restaurant
financings.
 
    INCOME TAXES.  The provision for income taxes in 1997 and 1996 is based on
the approximate tax rate applied to each year's pretax book income. The 1997
provision for income tax was adjusted by a valuation allowance equal to the net
deferred tax asset due to uncertainty as to its realization.

    Historically, we have experienced seasonal variability in our quarterly
operating results with higher sales per restaurant in the second and third
quarters than in the first and fourth quarters. The higher sales in the second
and third quarters affect profitability by reducing the impact of our
restaurants' fixed and semi-fixed costs, as well as through increased revenues.
This seasonal impact on our operating results is expected to continue.
 
INFLATION
 
    Components of our operations subject to inflation include food, beverage,
lease and labor costs. Our leases require us to pay taxes, maintenance, repairs,
insurance and utilities, all of which are subject to inflationary increases. We
believe inflation has not had a material impact on our results of operations in
recent years.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    We have funded our capital requirements in recent years through cash flow
from operations, private placements of preferred stock and bank debt. We
generated $4.2 million in cash flow from operating activities in 1998, $2.0
million in 1997 and $1.4 million in 1996. From 1995 through 1997, we raised
approximately $16.8 million, net of financing costs, from the sale of preferred
stock. We have also financed our capital requirements through bank borrowings.
As of March 28, 1999, the balance outstanding under our term loan agreement with
BankBoston, N.A. was approximately $1.7 million. On April 1, 1999 the loan
agreement was amended to provide for the outstanding balance to bear interest at
the lesser of (1) LIBOR adjusted by the statutory reserve rate plus 3.0%, or (2)
the greater of the bank's base rate plus 0.75% or the Federal Funds Effective
Rate plus 1.5%. In addition, we have a $7.5 million line of credit agreement
with BankBoston, which bears interest at the same rate as the term loan. As of
April 9, 1999, there was approximately $1.0 million outstanding under this
agreement.
    
 
    Our principal financial needs arise from the development and opening of new
units. We incurred capital expenditures of approximately $6.9 million during
1998, of which $6.6 million was for new unit openings. In 1997 we incurred
approximately $6.4 million in capital expenditures, of which $5.0 million was
for new unit openings and $1.0 million for the modification to the Baja Grill
concept. In 1996, we incurred $3.0 million in capital expenditures, of which
$2.6 million was for new unit openings.
 
   
    Total capital expenditures in 1999 are expected to be approximately $11.7
million, of which approximately $10.0 million is expected to be invested in the
opening of new restaurants. Approximately $2.6 million of this was incurred in
the first quarter. We plan to open 28 units in 1999, and 36 units in 2000. We
expect that future locations will generally cost approximately $360,000 per unit
net of landlord allowances and excluding pre-opening expenses. Pre-opening
expenses are expected to average approximately $20,000 per restaurant.
    
 
   
    We lease restaurant and office facilities and real property under operating
leases expiring through 2013. As of the date of this prospectus, our future
minimum lease payments for our headquarters and restaurants are as follows: $4.4
million in 1999, $5.0 million in 2000, $5.0 million in 2001, $4.9 million in
2002, and $4.9 million in 2003 and $19.4 million thereafter.
    
 
    We believe that the proceeds from this offering, together with anticipated
cash flow from operations and funds anticipated to be available from a credit
facility, will be sufficient to satisfy our working capital and capital
expenditure requirements for at least the next 12 months. We plan to incur
substantial costs over the near term in connection with our expansion program.
Changes in our operating plans, acceleration of our expansion plans, lower than
anticipated sales, increased expenses, potential acquisitions or other events
may cause us to seek additional financing sooner than anticipated. Additional
financing may not be available on acceptable terms, or at all. Failure to obtain
additional financing as needed could have a material adverse effect on our
business and results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    Our market risk exposures are related to our cash, cash equivalents and
investments. We invest our excess cash in highly liquid short-term investments
with maturities of less than one year and U.S. Treasury notes and
mortgage-backed securities with maturities in excess of one year. We do not feel
these are a significant market risk.
 
YEAR 2000 READINESS DISCLOSURE
 
    Historically, most computer databases, as well as embedded microprocessors
in computer systems and industrial equipment, were designed with date data using
only two digits of the year. Most computer programs, computers and embedded
microprocessors controlling equipment were programmed to assume that all two
digit dates were preceded by "19," causing "00" to be interpreted as the year
1900. This formerly common practice now could result in a computer system or
embedded microprocessor which fails to recognize properly a year that begins
with "20," rather than "19." This in turn could result in computer system
miscalculations or failures, as well as failures of equipment controlled by date
sensitive microprocessors, and is generally referred to as the "year 2000"
issue.
 
    OUR STATE OF YEAR 2000 READINESS
 
    We have reviewed both our information technology and our non-information
technology systems to determine whether they are year 2000 compliant. We have
not identified any material systems which are not year 2000 compliant. We have
initiated formal communications with all significant supplier and service
providers to determine the extent to which we are vulnerable to those third
parties' failures to solve their year 2000 problem. We have received written
assurances of year 2000 compliance from a majority of the third parties with
whom we have relationships, including our point-of-sale, payroll, and credit
card service providers. Testing and replacement of all systems is scheduled to
be completed by July 1, 1999. We intend to continue to make efforts to ensure
that third parties with whom we have relationships are year 2000 compliant.
 
    THE COSTS TO ADDRESS OUR YEAR 2000 ISSUES
 
    We estimate that we have incurred costs of less than $25,000 to date in
connection with our year 2000 plan. We currently estimate the total costs of
completing our year 2000 plan, including costs incurred to date, to be less than
$50,000. This estimate is based on currently available information and will be
updated as we continue our assessment of third-party relationships, proceed with
our testing and implementation and design contingency plans.
 
    THE RISKS OF OUR YEAR 2000 ISSUES
 
   
    If any information technologies or embedded microprocessor technology
systems critical to our operations have been overlooked, there could be a
material adverse effect on our business or results of operations of a magnitude
which we have not yet fully analyzed. If the vendors of most important goods and
services or the suppliers of our necessary energy, telecommunications and
transportation needs, fail to provide us with:
    
 
   
    - the materials and services which are necessary to produce, distribute and
      sell our products;
    
 
   
    - the electrical power and other utilities necessary to sustain our
      operations; or
    
 
   
    - reliable means of transporting supplies to our restaurants, such failure
      could affect our ability to sell product which could have a material
      adverse effect on our business or results of operations.

<PAGE>
    OUR CONTINGENCY PLAN
 
   
    We are in the initial stages of developing a business contingency plan to
address both unavoided and unavoidable year 2000 risks. This plan currently
includes developing and maintaining relationships with several suppliers of
services and products to mitigate a "worst case" scenario in which one or more
of our suppliers are not year 2000 compliant. Although we expect to have the
plan well-developed and costs of the plan estimated by July 31, 1999,
enhancements and revisions will be continuously considered and implemented as
appropriate.
    
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
   
    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including derivative instruments embedded
in other contracts, and for hedging activities. SFAS No. 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 1999. We have not
yet assessed the effect of this standard on our current reporting and
disclosures.
    
 
   
    In April 1998, Statement of Position 98-5, "Reporting on the Costs of
Start-Up Activities" was issued by the Accounting Standards Executive Committee.
SOP 98-5 provides guidance on the financial reporting of start-up costs and
organization costs. It requires costs of start-up activities and organization
costs to be expensed as incurred, and is effective for fiscal years beginning
after December 15, 1998. We chose to early adopt this SOP for the fiscal year
ended December 28, 1997. The adoption of this SOP did not have a material effect
on our operations.

OVERVIEW
    
 
   
    We own and operate 67 high-quality, quick-service Mexican restaurants under
the name "Rubio's Baja Grill" located principally in the southwest region of the
United States. Our restaurants offer a distinctive blend of high-quality,
traditional Mexican cuisine combined with fresh seafood fare indicative of the
Baja region of Mexico.
    
 
RUBIO'S BAJA GRILL CONCEPT
 
    The Rubio's Baja Grill concept successfully evolved from the original
"Rubio's, Home of the Fish Taco" concept, which our co-founder Ralph Rubio first
developed following his college spring break trips to the Baja peninsula of
Mexico in the mid-1970s. Ralph opened the first Rubio's restaurant with his
father, Rafael, over 16 years ago in the Mission Bay area of San Diego. Building
on the success of our original "fish taco" concept, we later expanded our menu
offerings and upgraded our store layout to appeal to a broader customer base. We
seek to differentiate our restaurants by providing high-quality Mexican food in
a quick-service environment. We believe the "Rubio's Baja Grill" concept is
uniquely positioned between the quick-service and casual dining segments of the
restaurant industry. The critical elements of our market positioning are as
follows:
 
    - DISTINCTIVE, FRESH, HIGH-QUALITY FOOD.  We seek to differentiate ourselves
      from other quick-service and fast food Mexican restaurants by offering
      high-quality products made-to-order using authentic regional Baja Mexican
      recipes. We have experienced a high degree of success to date developing
      distinctive and flavorful offerings that generate strong customer loyalty
      and are often described as "craveable." Our signature items include our
      Baja-style fish tacos as well as limited time promotions such as our
      lobster burrito and tequila shrimp burrito. Our menu is served at both
      lunch and dinner. It features a variety of other freshly prepared items,
      including tacos and burritos made with chargrilled chicken, steak, mahi
      mahi and shrimp, as well as grilled quesadillas. Freshly prepared salsas
      are offered at our complimentary salsa bar. Our menu also includes reduced
      fat "Healthmex" offerings and "Kid Pesky" meals designed for children.
 
    - CASUAL, FUN DINING EXPERIENCE.  We strive to promote an enjoyable overall
      customer experience by creating a fun and relaxed setting in each of our
      restaurants. Unlike the generic decor of a typical fast food restaurant,
      our restaurants are designed to create an authentic personality capturing
      the relaxed, beach-like atmosphere of the Baja region of Mexico. Our
      design elements include colorful Mexican tiles, saltwater aquariums with
      tropical fish, Baja beach photos and tropical prints, surfboards on the
      walls and authentic palm-thatched patio umbrellas, or palapas, in most
      existing locations.
 
    - EXCELLENT DINING VALUE.  Our restaurants offer guests high-quality food
      typically associated with sit-down, casual dining restaurants at
      quick-service prices. In addition to favorable prices, we offer the
      convenience and rapid delivery of a traditional quick-service format. We
      provide guests a clean and comfortable environment in which to enjoy their
      meal on site. We also offer guests the convenience of take-out service. We
      believe the strong value we deliver to our customers is critical to
      building strong repeat business and customer loyalty.

OUR BUSINESS STRATEGIES
 
    Our business objective is to become the leading high-quality, quick-service
Mexican restaurant brand nationwide. In order to achieve our business objective,
we have developed the following strategies:
 
   
    - CREATE A DISTINCTIVE CONCEPT AND BRAND.  Our restaurants provide guests
      with a distinctive dining experience which, we believe, helps promote
      frequent visiting patterns and strong customer loyalty. We continue to
      focus on several key initiatives designed to enhance the performance of
      our existing restaurants and strengthen our brand identity. These
      initiatives include developing and expanding proprietary menu offerings
      such as the Baja-style fish taco, lobster burrito and "Baja Bowl," a
      flavorful combination of chargrilled steak or chicken served over rice and
      beans with fresh tomatoes, onions and cilantro. In addition, we focus on
      securing high-visibility, high-traffic store locations and promoting the
      awareness of our brand through comprehensive regional and local media
      campaigns. As a result of these initiatives, we experienced comparable
      store sales increases of 10.4% in 1998 and 18.0% in 1997.
    
 
    - ACHIEVE ATTRACTIVE RESTAURANT-LEVEL ECONOMICS.  We believe that we have
      been able to achieve attractive operating results due to the broad appeal
      of our concept, careful site selection and cost-effective development,
      consistent application of our management and training programs and
      favorable product costs. We utilize centralized information and accounting
      systems which allow our management to monitor and control labor, food and
      other direct operating expenses, and provide them with timely access to
      financial and operating data. We believe we achieve a lower-than-average
      product cost compared to our competitors, due to the popularity of our
      fish items versus higher-cost items such as chicken and steak. We also
      believe that our culture and emphasis on training leads to a lower
      employee turnover ratio, and therefore higher productivity, compared to
      many of our competitors.
 
   
    - EXECUTE DISCIPLINED EXPANSION STRATEGY.  We believe that our restaurant
      concept has broad national appeal and that, as a result, we have
      significant opportunities to expand our operations and generate attractive
      unit level economics. With the addition of selected senior management in
      operations, development, marketing and finance in 1996, we implemented an
      accelerated expansion strategy. Our current expansion plan calls for us to
      open 28 restaurants in 1999 and 36 restaurants in 2000. Through our
      rigorous site selection process and criteria developed by our real estate
      committee, we principally target high-traffic, high-visibility locations
      in urban and suburban markets with medium to high family income levels.
    
 
    - ENSURE HIGH-QUALITY GUEST EXPERIENCE.  We strive to provide a consistent,
      high-quality guest experience in order to generate frequent visiting
      patterns and brand loyalty. To achieve this goal, we focus on creating a
      fun, team-like culture for our restaurant employees, which we believe
      fosters a friendly and inviting atmosphere for our guests. Through
      extensive training, experienced restaurant-level management and rigorous
      operational controls, we seek to ensure prompt, friendly and efficient
      service to our guests. Our commitment to making each guest's experience a
      consistently positive one is evidenced by Rubio's list of "House Rules",
      which is prominently displayed in each restaurant and defines the high
      level of quality and service our guests can expect from us. Overall, we
      design our concept to appeal to a broad variety of guests, including
      families, and believe the cleanliness of our facilities provides an
      additional advantage over many of our competitors.

UNIT ECONOMICS
 
   
    In 1998, the 43 units open the entire year generated on a per unit basis
average sales of $901,000, average operating income of $148,000, or 16.4% of
sales, and average cash flow of $183,000, or 20.3% of sales. Comparable
restaurant sales increased 10.4% in 1998, following an 18.0% increase in 1997.
In addition, comparable restaurant sales increased 13.7% in the first quarter of
1999, as compared to a 7.6% increase in the same period of 1998.
    
 
   
    We currently have 12 units open outside California. Of these, three units
have over 12 months of operating results. These units generated average sales of
$972,000 for the most recent 12 months, average operating income of $149,000, or
15.0% of sales, and average cash flow of $200,000 or 20.5% of sales. These
results are not necessarily indicative of the results we will obtain in
connection with the other units currently open, or those we may open in the
future.
    
 
    We currently lease all of our restaurant locations with the exception of one
owned building. We plan to continue to lease substantially all of our future
restaurant locations in order to minimize the cash investment associated with
each unit. Our site selection strategy is to locate our restaurants in
high-profile, high-traffic locations, preferably on an end-cap location in line
with other retail properties.
 
    Historically, the size of our restaurants has generally ranged from 1,800 to
3,000 square feet, excluding our smaller, food court locations. We expect the
size of our future sites to range from 2,000 to 2,400 square feet. We intend to
continue to develop restaurants that will require, on average, a total cash
investment of approximately $380,000, including pre-opening expenses of $20,000.

EXISTING AND PROPOSED LOCATIONS
 
   
    The following table sets forth information about our existing and proposed
units. We currently operate 67 restaurant facilities under the name "Rubio's
Baja Grill," with 27 restaurants in San Diego county, 28 restaurants in greater
Los Angeles, which includes Los Angeles, Orange, San Bernardino and Riverside
counties, six restaurants in Phoenix, Arizona, four restaurants in Las Vegas,
Nevada and two restaurants in Denver, Colorado. In addition, we license our
concept to other restaurant operators for three non-traditional locations at
Qualcomm Stadium, the San Diego International Airport food court and the Del Mar
Thoroughbred Club. Four of the 20 units we plan to open in the balance of 1999
are under construction. We have signed leases for an additional 19 units. The
majority of our units are in high-traffic retail centers, and are not
stand-alone units.

EXPANSION AND SITE SELECTION
 
   
    We plan to open 28 units during 1999, eight of which have opened to date,
and 36 units in 2000. Leases for 10 of the 36 units to be opened in 2000 have
been signed. We opened our first unit outside of California in Phoenix, Arizona
in April 1997. We currently operate a total of 12 units outside of California,
including six in Arizona, four in Las Vegas and two in Denver. We are
negotiating new leases in all of our current markets, in addition to Salt Lake
City, Sacramento and Minneapolis.
    
 
    Our expansion strategy targets major metropolitan areas that have attractive
demographic characteristics. Once a metropolitan area is selected, we identify
viable trade areas that have high-traffic patterns, strong demographics, such as
high density of white collar families, medium to high family incomes, high
education levels, and density of both daytime employment and residential
developments, limited competition within the trade area and strong retail and
entertainment developments. Within a desirable trade area, we select sites that
provide specific levels of visibility, accessibility, parking, co-tenancy and
exposure to a large number of potential customers.
 
    We believe that the quality of our site selection criteria is critical to
our continuing success. Therefore, our senior management team is actively
involved in the selection of each new market and specific site, personally
visiting all new markets and most sites or conducting a video site tour of all
sites prior to granting final approval. Each new market and site must be
approved by our Real Estate Site Acquisition Committee, which consists of
members of senior management. This process allows us to analyze each potential
location taking into account its effect on all aspects of our business.
 
   
    In connection with our strategy to rapidly expand into selected markets, we
expect to evaluate the merits of initiating a franchising program. We are not
sure when or if we will decide to franchise our concept or how extensively we
will pursue such a strategy. Adopting a franchising strategy would require us to
devote management and financial resources to build the operational
infrastructure needed to support the franchise of our restaurants. If we
implemented a franchising program, we would earn revenue through initial
franchise fees payable to us by franchisees and through royalty income based on
a percentage of restaurant sales. Franchising programs typically involve
substantially lower initial cash investments compared to unit expansion
strategies where company-owned units are developed and leased. Franchising
programs involve risks. Please see "Risk Factors--If we adopt a franchising
strategy, we may be unsuccessful in executing a franchising program" for a
description of the risks associated with franchising programs.
    
 
MENU
 
    Our menu features made-to-order burritos, soft-shell tacos, and quesadillas
made with marinated, chargrilled chicken breast and lean steak, as well as
seafood indicative of the Baja region of Mexico, such as chargrilled mahi mahi,
sauteed shrimp and our signature Baja-style fish taco. Side items including our
chips, beans and rice are all made fresh daily. Other ingredients, such as our
fresh, handmade guacamole, shredded natural cheeses and our zesty chipotle
sauce, also contribute to our quality image and distinctive flavor profiles. We
also offer a self-serve salsa bar where guests can choose from three different
salsas made fresh every day at each restaurant. Our prices range from $1.79 for
a Baja-style fish taco to $5.69 for a Cabo Combo, which includes a shrimp
burrito, fish taco, chips and beans. Most units also offer a selection of
imported Mexican and domestic beers.
 
   
    To provide added variety, from time to time we introduce limited time
offerings such as our lobster burrito, tequila shrimp burrito, "killer" shark
tacos and Baja Bowls. Some of these items have been permanently added to the
menu, such as the Baja Bowl. Other items, such as the lobster burrito, are
offered seasonally due to limited availability.
    
 
    Substantially all of our units include a HealthMex section on their menu and
Kid Pesky meals designed for children. Our HealthMex items are designed to have
less than 22% of their calories from
 
                                       31
<PAGE>
fat, and include a chargrilled mahi mahi taco or a chargrilled chicken burrito
served on a whole wheat tortilla. The Kid Pesky meals consist of a choice of a
fish taco, chicken taquitos, quesadilla or a bean and cheese burrito, along with
a side dish, drink, churro dessert and toy surprise.
 
DECOR AND ATMOSPHERE
 
    We believe that the decor and atmosphere of our restaurants is a critical
factor in our guests' overall dining experience. We strive to create the
relaxed, casual environment that is reminiscent of the Baja region of Mexico.
Our design elements include colorful Mexican tiles, saltwater aquariums with
tropical fish, Baja beach photos and tropical prints, surfboards on the walls
and authentic palm-thatched patio umbrellas, or palapas, in most existing
locations. We believe the decor and atmosphere of our restaurants appeal to a
broad variety of consumers, including families.
 
MARKETING
 
    We utilize broadcast advertising as a marketing tool to increase our brand
awareness, attract new guests and build customer loyalty. Our advertising is
designed to portray ourselves as a high-quality, quick-service Mexican food
restaurant and to promote special offers to increase sales. Examples of these
offers include limited-time-only product introductions, such as our lobster
burrito or tequila shrimp burrito, as well as price promotions, such as our
99-cent fish taco special. Media used for these promotions include television,
radio, coupons and in-store merchandising materials. We believe word-of-mouth
advertising is also a key component in attracting new guests.
 
    As part of our expansion strategy, we select target markets which we believe
will support multiple units and the efficient use of broadcast advertising. Upon
entry into each new market, we also hire local public relations firms to help
establish brand awareness for our restaurants as we build toward media
efficiency. In 1998, we spent approximately $1.4 million on marketing. We expect
our marketing expenditures to increase as we add new restaurants and expand into
new markets.
 
OPERATIONS
 
    UNIT MANAGEMENT AND EMPLOYEES
 
   
    Our typical restaurant employs one general manager, one to two assistant
managers and 22 to 25 hourly employees, approximately 60% of which are full-time
employees and approximately 40% of which are part-time employees. The general
manager is responsible for the day-to-day operations of the restaurant,
including food quality, service, staffing and purchasing. We seek to hire
experienced general managers and staff and to motivate and retain them by
providing opportunities for increased responsibilities and advancement, as well
as performance-based cash incentives. These performance incentives are tied to
sales, profitability and qualitative measures such as mystery shoppers, who
anonymously evaluate individual restaurants. We also grant general managers
options to purchase shares of our common stock when hired or promoted. All
employees working more than 20 hours per week are eligible for health benefits
and participation in our 401(k) plan.
    
 
    We currently employ 11 district managers, each of whom reports either to a
regional manager or to the director of operations. These district managers
direct unit management in all phases of restaurant operations, as well as assist
in opening new units. We also grant district managers options to purchase shares
of our common stock when hired or promoted.
 
    TRAINING
 
    We strive to maintain quality and consistency in each of our units through
the careful training and supervision of personnel and the establishment of, and
adherence to, high standards relating to personnel performance, food and
beverage preparation and maintenance of facilities. We have
 
                                       32
<PAGE>
implemented a training program that is designed to teach new managers the
technical and supervisory skills necessary to direct the operations of our
restaurants in a professional and profitable manner. Each manager must
successfully complete a five-week training course, which includes hands-on
experience in both the kitchen and dining areas. We have also prepared
operations manuals and videotapes relating to food and beverage handling,
preparation and service. In addition, we maintain a continuing education program
to provide our unit managers with ongoing training and support. We strive to
maintain a team-oriented atmosphere and instill enthusiasm and dedication in our
employees. We regularly solicit employee suggestions concerning the improvement
of our operations in order to be responsive to both them and our guests.
 
    QUALITY CONTROLS
 
    Our emphasis on excellent customer service is enhanced by our quality
control programs. We welcome comments on the quality of service and food at our
restaurants by maintaining a toll-free customer hotline and distributing
customer surveys. District managers are directly responsible for ensuring that
these comments are addressed to achieve a high level of customer satisfaction.
Our Director of Food and Beverage is also responsible for ensuring product
consistency and quality among our restaurants. Furthermore, we engage a
third-party service whereby an anonymous customer or mystery shopper evaluates
and reports to management key elements of the Rubio's experience, including
product quality, cleanliness and customer service.
 
    HOURS OF OPERATIONS
 
    Our units are generally open Sunday through Thursday from 10:30 a.m. until
10:00 p.m., and on Friday and Saturday from 10:30 a.m. until 11:00 p.m.
 
MANAGEMENT INFORMATION SYSTEMS
 
    All of our restaurants use computerized point-of-sale systems, which are
designed to improve operating efficiency, provide corporate management timely
access to financial and marketing data, and reduce restaurant and corporate
administrative time and expense. These systems record each order and print the
food requests in the kitchen for the cooks to prepare. The data captured for use
by operations and corporate management include gross and sales amounts, cash and
credit card receipts, and quantities of each menu item sold. Sales and receipts
information is generally transmitted to the corporate office daily, where it is
reviewed and reconciled by the accounting department before being recorded in
the accounting system. The daily sales information is polled nightly to the
corporate office and distributed to management via electronic mail each morning.
The point-of-sale system also calculates daily ideal usage and cost for the top
10 food items which make up approximately 85% of total food cost. A monthly
trend report of actual food cost compared to ideal food cost is also prepared.
We are currently installing a back office system, including personal computers
in each of our restaurants, which will allow managers to compare actual food
cost to ideal food costs on a daily basis. As of the date of this prospectus,
this system is currently operational in over half of our restaurants, and is
expected to be installed in all of our restaurants by the end of 1999.
 
    Our corporate systems provide management with operating reports that show
restaurant performance comparisons with budget and prior year results both for
the accounting period and year-to-date, as well as trend formats by both dollars
and percents of sales. These systems allow us to closely monitor restaurant
sales, cost of sales, labor expense and other restaurant trends on a daily,
 
                                       33
<PAGE>
weekly, and monthly basis. We believe these systems will enable both unit and
corporate management to adequately manage the operational and financial
performance of the restaurants in support of our planned expansion.
 
PURCHASING
 
   
    We strive to obtain consistently high-quality ingredients at competitive
prices from reliable sources. To attain operating efficiencies and to provide
fresh ingredients for our food products while obtaining the lowest possible
prices for the required quality, purchasing employees at the corporate office
control the purchasing of food items through buying from a variety of national,
regional and local suppliers at negotiated prices. Most food and other products
are shipped from a central distributor directly to the units two to four times
per week. Produce and tortillas are delivered daily from local suppliers to
ensure product freshness. We do not maintain a central food product warehouse or
commissary. As is typical in our industry, we do not have any long-term
contracts with our food suppliers. We have not experienced significant delays in
receiving our food and beverage inventories, restaurant supplies or equipment.
    
 
COMPETITION
 
    The restaurant industry is intensely competitive. There are many different
segments within the restaurant industry that are distinguished by types of
service, food types and price/value relationships. We position our restaurants
in the high-quality, quick-service Mexican food segment of the industry. In this
segment, our direct competitors include Baja Fresh, La Salsa and Chipotle. We
also compete indirectly with full-service Mexican restaurants including Chevy's,
Chi Chi's and El Torito and fast food restaurants, particularly those focused on
Mexican food such as Taco Bell and Del Taco. Competition in our industry segment
is based primarily upon food quality, price, restaurant ambiance, service and
location. Although we believe we compete favorably with respect to each of these
factors, many of our direct and indirect competitors are well-established
national, regional or local chains and have substantially greater financial,
marketing, personnel and other resources than we do. We also compete with many
other retail establishments for site locations.
 
PROPERTIES
 
    Our corporate headquarters are located in Carlsbad, California. We occupy
this facility under a lease which terminates in August 31, 2005, with options to
extend the lease for an additional 13 years. We lease each of our restaurant
facilities with the exception of the El Cajon unit, which is covered by a ground
lease. The majority of our leases are for 10-year terms and include options to
extend the terms. The majority of our leases also include both fixed rate and
percentage-of-sales rent provisions. The landlord of our San Diego State
University unit has the right to terminate the lease, with 60 days notice, in
the event a proposed redevelopment project commences work.
 
TRADEMARKS
 
    Our registered trademarks and service marks include "Rubio's," "Baja Grill,"
"Home of the Fish Taco," "HealthMex" and "Pesky" with the United States Patents
and Trademark Office. We believe that our trademarks, service marks and other
proprietary rights have significant value and are important to the marketing of
our restaurant concept. We have in the past and expect to continue to vigorously
protect our proprietary rights. We cannot predict, however, whether steps taken
by us to protect our proprietary rights will be adequate to prevent
misappropriation of these rights or the use by others of restaurant features
based upon, or otherwise similar to, our concept. It may be difficult for us to
prevent others from copying elements of our concept and any litigation to
enforce our rights will likely be costly. In addition, other local restaurant
operations with names similar to those we use may try to prevent us from using
our marks in those locales.

EMPLOYEES
 
   
    As of April 21, 1999, we had approximately 1,860 employees, including
approximately 40 employees located at our corporate headquarters.
    
 
GOVERNMENT REGULATION
 
   
    Our restaurants are subject to licensing and regulation by state and local
health, sanitation, safety, fire and other authorities, including licensing and
regulation requirements for the sale of alcoholic beverages and food. To date,
we have not experienced an inability to obtain or maintain any necessary
licenses, permits or approvals, including restaurant, alcoholic beverage and
retail licensing. The development and construction of additional units will also
be subject to compliance with applicable zoning, land use and environmental
regulations. For a description of risks faced by us related to government
regulation, please see "Risk Factors--We may not be able to obtain and maintain
state and local permits necessary to operate our units."
    
 
LEGAL PROCEEDINGS
 
    As of the date of this prospectus, we are not a party to any material
litigation.

BOARD COMMITTEES
 
    AUDIT COMMITTEE.  The audit committee of the board of directors reviews,
acts on and reports to the board of directors with respect to various auditing
and accounting matters, including the recommendation of our auditors, the scope
of the annual audits, fees to be paid to the auditors, the performance of our

directors recommends, reviews and oversees the salaries, benefits and stock
option plans for our employees, consultants, directors and other individuals

plans. The members of the compensation committee are Messrs. Anderson, Fish and

DIRECTOR COMPENSATION
 
   
    Directors do not receive cash compensation for their service on our board of
directors. Non-employee directors are reimbursed for reasonable expenses
incurred in connection with serving as a director. In January 1997, we granted a
non-qualified stock option to purchase 25,000 shares of common stock to Mr.
Lopdrup, a non-employee director. The option granted to Mr. Lopdrup was fully
exercised by Mr. Lopdrup and is subject to a right of repurchase in our favor
which lapses over a period of five years from the date of grant. In April 1999,
we granted options to purchase 25,000 shares of our common stock to each of Mr.
Dooling and Mr. Ryan in connection with their election to our board of
directors. 15,000 shares are immediately vested, with the remaining 10,000
shares vesting over the next two years. Vesting of any options previously
granted to board members will automatically accelerate in the event of a sale,
acquisition or merger of Rubio's. Each individual who first becomes a
non-employee member of the board of directors at any time after the offering
will receive an option to purchase 25,000 shares of common stock on the date
such individual joins the board of directors, provided such individual has not
previously been employed by us or any parent or subsidiary corporation. In
addition, on the date of each annual stockholders' meeting beginning in 2000,
each
    
 
                                       38
<PAGE>
non-employee member of the board of directors will automatically be granted an
option to purchase 5,000 shares of common stock, provided such individual has
served as a non-employee member of the board of directors for at least six
months. For a discussion of our automatic option grant program and accelerated
vesting of options under the 1999 Plan, please see "--Benefit Plans."

STOCK OPTION INFORMATION
 
   
    The following table sets forth information regarding options granted to the
executive officers listed in the Summary Compensation Table during fiscal 1998.
We have not granted any stock appreciation rights.
    
 
    Each option represents the right to purchase one share of common stock. The
options shown in this table are all incentive stock options granted under our
stock option plans. The options vest on the following schedule: 20% of the
options vest after the completion of one year of service from the grant date and
the remainder of the options vest in equal monthly installments over the next 48
months of
 
                                       39

    The exercise price per share of each option was equal to the fair market
value of the common stock on the date of grant as determined by our board after
consideration of a number of factors, including, but not limited to, our
financial performance, market conditions and the price, preferred rights and
privileges of shares of equity securities sold to or purchased by outside
investors.
 
   
    The potential realizable value at assumed annual rates of stock price
appreciation for the option term represents hypothetical gains that could be
achieved for the respective options if exercised at the end of the option term.
The 5% and 10% assumed annual rates of compounded stock price appreciation are
mandated by rules of the SEC and do not represent our estimate or projection of
our future common stock prices. These amounts represent assumed rates of
appreciation in the value of our common stock from the fair market value on the
date of grant. Actual gains, if any, on stock option exercises are dependent on
the future performance of the common stock and overall stock market conditions.
The amounts reflected in the table may not necessarily be achieved.

BENEFIT PLANS
 
    1999 STOCK INCENTIVE PLAN
 
    Our 1999 Stock Incentive Plan is intended to serve as the successor equity
incentive program to our 1998 Stock Option/Stock Issuance Plan, 1995 Stock
Option/Stock Issuance Plan and 1993 Stock Option/Stock Issuance Plan. Our 1999
plan was adopted by our board and stockholders in March 1999. Our 1999 plan will
become effective on the date the underwriting agreement is signed in connection
with this offering of our common stock. All outstanding options under the
predecessor plans will be incorporated into our 1999 plan on the date this plan
is effective, and no further option grants will be made under the predecessor
plans after such date. The incorporated options will continue to be governed by
their existing terms, unless the plan administrator elects to extend one or more
features of our 1999 plan to those options. Except as otherwise noted below, the
incorporated options will have substantially the same terms as in effect for
grants made under the discretionary option grant program of our 1999 plan.
 
   
    An initial reserve of 1,123,938 shares of common stock has been authorized
for issuance under our 1999 plan. Such share reserve consists of (1)
approximately the number of shares which will remain available for issuance
under the predecessor plans on the date our 1999 plan becomes effective,
including the shares subject to outstanding options thereunder, plus (2) an
additional increase of approximately 500,000 shares. The number of shares of
common stock reserved for issuance under our 1999 plan will automatically
increase on the first trading day in January each calendar year, beginning in
calendar year 2000, by an amount equal to 3% of the total number of shares of
common stock outstanding on the last trading day in December of the preceding
calendar year, but in no event will any such annual increase exceed 450,000
shares. In addition, no participant in our 1999 plan may be granted stock
options, separately exercisable stock appreciation rights and direct stock
issuances for more than 500,000 shares of common stock in the aggregate per
calendar year.
    
 
    Our 1999 plan is divided into five separate components:
 
   
    - the discretionary option grant program, under which eligible individuals
      in our employ or service including officers, non-employee board members
      and consultants may, at the discretion of the plan administrator, be
      granted options to purchase shares of common stock at an exercise price
      not less than 100% of the fair market value of those shares on the grant
      date;
    
 
   
    - the stock issuance program, under which such individuals may, in the plan
      administrator's discretion, be issued shares of common stock directly,
      through the purchase of such shares at a price not less than 100% of their
      fair market value at the time of issuance or as a bonus tied to the
      performance of services;
    
 
   
    - the salary investment option grant program, which may, at the plan
      administrator's sole discretion, be activated for one or more calendar
      years and, if so activated, will allow executive officers and other highly
      compensated employees the opportunity to apply a portion of their base
      salary to the acquisition of special below-market stock option grants;
    
 
   
    - the automatic option grant program, under which option grants will
      automatically be made at periodic intervals to eligible non-employee board
      members to purchase shares of common stock at an exercise price equal to
      100% of the fair market value of those shares on the grant date; and
    
 
   
    - the director fee option grant program, which may, in the plan
      administrator's sole discretion, be activated for one or more calendar
      years and, if so activated, will allow non-employee board
    
 
                                       41
<PAGE>
      members the opportunity to apply a portion of the annual retainer fee
      otherwise payable to them in cash each year to the acquisition of special
      below-market option grants.
 
    The discretionary option grant program and the stock issuance program will
be administered by the compensation committee. The compensation committee as
plan administrator will have complete discretion to determine which eligible
individuals are to receive option grants or stock issuances under those
programs, the time or times when such option grants or stock issuances are to be
made, the number of shares subject to each such grant or issuance, the status of
any granted option as either an incentive stock option or a non-statutory stock
option under the federal tax laws, the vesting schedule to be in effect for the
option grant or stock issuance and the maximum term for which any granted option
is to remain outstanding. However, the board acting by disinterested majority
will have the exclusive authority to make any discretionary option grants or
stock issuances to members of the compensation committee. The compensation
committee will also have the exclusive authority to select the executive
officers and other highly compensated employees who may participate in the
salary investment option grant program in the event that program is activated
for one or more calendar years. Neither the compensation committee nor the board
will exercise any administrative discretion with respect to option grants under
the salary investment option grant program or under the automatic option grant
or director fee option grant program for the non-employee board members. All
grants under those latter three programs will be made in strict compliance with
the express provisions of each such program.
 
    The exercise price for the shares of common stock subject to option grants
made under our 1999 plan may be paid in cash or in shares of common stock valued
at fair market value on the exercise date. The option may also be exercised
through a same-day sale program without any cash outlay by the optionee. In
addition, the plan administrator may provide financial assistance to one or more
optionees in the exercise of their outstanding options or the purchase of their
unvested shares by allowing such individuals to deliver a full-recourse,
interest-bearing promissory note in payment of the exercise price and any
associated withholding taxes incurred in connection with such exercise or
purchase.
 
   
    The plan administrator will have the authority to cancel outstanding options
under the discretionary option grant program, including options incorporated
from the predecessor plans, in return for the grant of new options for the same
or different number of option shares with an exercise price per share based upon
the fair market value of our common stock on the new grant date.
    
 
    Stock appreciation rights are authorized for issuance under the
discretionary option grant program. Such rights will provide the holders with
the election to surrender their outstanding options for an appreciation
distribution from us equal to the excess of (1) the fair market value of the
vested shares of common stock subject to the surrendered option over (2) the
aggregate exercise price payable for those shares. Such appreciation
distribution may be made in cash or in shares of common stock. None of the
incorporated options from the predecessor plans contain any stock appreciation
rights.
 
   
    In the event that we are acquired by merger or asset sale, each outstanding
option under the discretionary option grant program which is not to be assumed
by the successor corporation will automatically accelerate in full, and all
unvested shares under the discretionary option grant and stock issuance programs
will immediately vest, except to the extent our repurchase rights with respect
to those shares are to be assigned to the successor corporation. The plan
administrator will have complete discretion to grant one or more options under
the discretionary option grant program which will become fully vested for all
the option shares in the event those options are assumed in the acquisition and
the optionee's service with us or the acquiring entity involuntarily terminates
within a designated period following such acquisition, not to exceed 18 months.
The vesting of outstanding shares under the stock issuance program may be
accelerated upon similar terms and conditions. The plan administrator
    
 
                                       42
<PAGE>
will also have the authority to grant options which will immediately vest upon
an acquisition of us, whether or not those options are assumed by the successor
corporation.
 
   
    The plan administrator is also authorized under the discretionary option
grant and stock issuance programs to grant options and to structure repurchase
rights so that the shares subject to those options or repurchase rights will
immediately vest in connection with a change in ownership or control of us,
whether by successful tender offer for more than 50% of the outstanding voting
stock or by a change in the majority of the board by reason of one or more
contested elections for board membership. Such accelerated vesting may occur
either at the time of such change or upon the subsequent involuntary termination
of the individual's service within a designated period following such change in
control, not to exceed 18 months.
    
 
   
    The options incorporated from the predecessor plans may, in the plan
administrator's discretion, immediately vest in the event of the following
changes in control (1) our merger or consolidation, or (2) the acquisition by
another corporation or person of (a) all or substantially all of our assets or
(b) 50% or more of our then outstanding voting stock, unless those options are
assumed or substituted in the acquisition of us. Options incorporated from the
predecessor plans are subject to provisions providing for accelerated vesting
upon a change in control. The plan administrator will have the discretion to
extend the acceleration provisions of our 1999 plan to any or all of the options
outstanding under the predecessor plans.
    
 
   
    In the event the plan administrator elects to activate the salary investment
option grant program for one or more calendar years, each of our executive
officers and other highly compensated employees selected for participation may
elect, prior to the start of the calendar year, to reduce his or her base salary
for that calendar year by a specified dollar amount not less than $10,000 nor
more than $50,000. Each selected individual who files such a timely election
will automatically be granted, on the first trading day in January of the
calendar year for which that salary reduction is to be in effect, a
non-statutory option to purchase that number of shares of common stock
determined by dividing the salary reduction amount by two-thirds of the fair
market value per share of common stock on the grant date. The option will be
exercisable at a price per share equal to one-third of the fair market value of
the option shares on the grant date. As a result, the fair market value of the
option shares on the grant date less the aggregate exercise price payable for
those shares will be equal to the amount of salary invested in that option. The
option will vest and become exercisable in a series of 12 equal monthly
installments over the calendar year for which the salary reduction is to be in
effect and will be subject to full and immediate vesting upon changes in the
ownership or control of us, as defined in the 1999 plan.
    
 
   
    Under the automatic option grant program, each individual who first becomes
a non-employee board member at any time after the completion of this offering
will automatically receive an option grant for 25,000 shares on the date such
individual joins the board, provided such individual has not been in our prior
employ. In addition, on the date of each annual stockholders meeting held after
the completion of this offering, each non-employee board member who is to
continue to serve as a non-employee board member will automatically be granted
an option to purchase 5,000 shares of common stock, provided such individual has
served on our board for at least six months.
    
 
    Each automatic grant will have a term of 10 years, subject to earlier
termination following the optionee's cessation of board service. The option will
be immediately exercisable for all of the option shares and will be immediately
vested.
 
    Should the director fee option grant program be activated in the future,
each non-employee board member will have the opportunity to apply all or a
portion of any annual retainer fee otherwise payable in cash to the acquisition
of a below-market option grant. The option grant will automatically be made on
the first trading day in January in the year for which the retainer fee would
otherwise be payable in cash. The option will have an exercise price per share
equal to one-third of the fair market value of the
 
                                       43
<PAGE>
   
option shares on the grant date, and the number of shares subject to the option
will be determined by dividing the amount of the retainer fee applied to the
program by two-thirds of the fair market value per share of common stock on the
grant date. As a result, the fair market value of the option shares on the grant
date less the aggregate exercise price payable for those shares will be equal to
the portion of the retainer fee invested in that option. The option will vest
and become exercisable for the option shares in a series of 12 equal monthly
installments over the calendar year for which the election is to be in effect.
However, the option will become immediately exercisable and vested for all the
option shares upon:
    
 
   
    - changes in the ownership or control of us, as defined in the 1999 plan; or
    
 
   
    - the death or disability of the optionee while serving as a board member.
    
 
   
    The shares subject to each option under the salary investment option grant
and director fee option grant programs will immediately vest upon:
    
 
   
    - an acquisition of us by merger or asset sale; or
    
 
   
    - the successful completion of a tender offer for more than 50% of our
      outstanding voting stock or a change in the majority of the board effected
      through one or more contested elections for board membership.
    
 
    Limited stock appreciation rights will automatically be included as part of
each grant made under the automatic option grant, salary investment option grant
and director fee option grant programs and may be granted to one or more of our
officers as part of their option grants under the discretionary option grant
program. Options with such a limited stock appreciation right may be surrendered
to us upon the successful completion of a hostile tender offer for more than 50%
of our outstanding voting stock. In return for the surrendered option, the
optionee will be entitled to a cash distribution from us in an amount per
surrendered option share equal to the excess of (1) the highest price per share
of common stock paid in connection with the tender offer over (2) the exercise
price payable for such share.
 
   
    The board may amend or modify our 1999 plan at any time, subject to any
required stockholder approval. Our 1999 plan will terminate on the earliest of:
    
 
   
    - March 17, 2009;
    
 
   
    - the date on which all shares available for issuance under our 1999 plan
      have been issued as fully-vested shares; or
    
 
   
    - the termination of all outstanding options in connection with changes in
      control or ownership of us, as defined in the 1999 plan.
    
 
    1999 EMPLOYEE STOCK PURCHASE PLAN
 
    Our 1999 Employee Stock Purchase Plan was adopted by our board and
stockholders in March 1999 and will become effective immediately upon the
execution of the underwriting agreement for this offering. Our employee stock
purchase plan is designed to allow our eligible employees to purchase shares of
common stock, at semi-annual intervals, through their periodic payroll
deductions under our employee stock purchase plan.
 
    An initial reserve of 200,000 shares of common stock has been authorized for
issuance under our employee stock purchase plan. Our employee stock purchase
plan will be implemented in a series of successive offering periods, each with a
maximum duration for 24 months. However, the initial offering period will begin
on the execution date of the underwriting agreement and will end on the last
business day in July 2001. The next offering period will commence on the first
business day in August 2001, and subsequent offering periods will commence as
designated by the plan administrator.
 
                                       44
<PAGE>
   
    Individuals who are scheduled to work more than 20 hours per week for more
than five calendar months per year on the start date of any offering period may
enter our employee stock purchase plan on that start date or on any subsequent
semi-annual entry date. Entry dates are the first business day of February or
August each year. Individuals who become eligible employees after the start date
of the offering period may join our employee stock purchase plan on any
subsequent semi-annual entry date within that offering period.
    
 
   
    Payroll deductions may not exceed 10% of the participant's cash earnings.
The accumulated payroll deductions of each participant will be applied to the
purchase of shares on his or her behalf on the last business day in January and
July each year at a purchase price per share equal to 85% of the lower of:
    
 
   
    - the fair market value of the common stock on the participant's entry date
      into the offering period; or
    
 
   
    - the fair market value on the semi-annual purchase date.
    
 
In no event, however, may any participant purchase more than 1,500 shares on any
semi-annual purchase date nor may all participants in the aggregate purchase
more than 50,000 shares on any such semi-annual purchase date. The plan
administrator may require shares of common stock purchased under our employee
stock purchase plan to be held for one year before they may be sold or otherwise
transferred.
 
    Should the fair market value per share of common stock on any purchase date
be less than the fair market value per share on the start date of the two-year
offering period, then that offering period will automatically terminate, and a
new two-year offering period will begin on the next business day, with all
participants in the terminated offering to be automatically transferred to the
new offering period.
 
   
    In the event we are acquired by merger or asset sale, all outstanding
purchase rights will automatically be exercised immediately prior to the
effective date of such acquisition. The purchase price will be equal to 85% of
the lower of:
    
 
   
    - the fair market value per share of common stock on the participant's entry
      date into the offering period in which such acquisition occurs; or
    
 
   
    - the fair market value per share of common stock immediately prior to such
      acquisition.
    
 
   
    Our employee stock purchase plan will terminate on the earlier of:
    
 
   
    - the last business day of July 2009;
    
 
   
    - the date on which all shares available for issuance under our employee
      stock purchase plan shall have been sold; or
    
 
   
    - the date on which all purchase rights are exercised in connection with an
      acquisition of us by merger or asset sale.
    
 
   
The board may at any time alter, suspend or discontinue our employee stock
purchase plan. However, some amendments to our employee stock purchase plan may
require stockholder approval.

                           DESCRIPTION OF SECURITIES
 
   
    The following information describes our common stock and preferred stock and
provisions of our certificate of incorporation and our bylaws as in effect upon
the closing of this offering. This description is only a summary. You should
also refer to the certificate and bylaws which have been filed with the SEC as
exhibits to our registration statement, of which this prospectus forms a part.
The descriptions of the common stock and preferred stock reflect changes to our
capital structure that will occur upon the closing of this offering.
    
 
   
    Upon the completion of the offering, our authorized capital stock will
consist of 75,000,000 shares of common stock, par value $0.001 per share, and
5,000,000 shares of preferred stock, par value $0.001 per share.
    
 
COMMON STOCK
 
   
    As of March 28, 1999, there were 1,085,036 shares of common stock
outstanding and held of record by 23 stockholders, assuming the exercise of all
common stock warrants that must be exercised prior to this offering. There will
be 8,601,624 shares of common stock outstanding upon the closing of this
offering.
    
 
   
    Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Accordingly, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of common stock are entitled to receive ratably
such dividends, if any, as may be declared by the board of directors out of
funds legally available for that purpose, subject to any preferential dividend
rights of any outstanding preferred stock. Holders of common stock have no
preemptive, subscription, redemption, liquidation or conversion rights. The
shares offered by us in this offering will be, when issued in consideration for
payment thereof, fully paid and nonassessable. The rights, preferences and
privileges of holders of common stock are subject to, and may be adversely
affected by, the rights of the holders of shares of any series of preferred
stock which we may designate and issue in the future. Upon the closing of this
offering, there will be no shares of preferred stock outstanding. With respect
to restrictions on alienability of shares of our common stock held by some of
our stockholders, please see "Shares Eligible for Future Sale."
    
 
PREFERRED STOCK
 
   
    As of March 28, 1999, there were 5,266,588 shares of convertible preferred
stock outstanding, assuming the exercise of all preferred stock warrants that
must be exercised prior to this offering. All outstanding shares of convertible
preferred stock will be converted into an aggregate of 5,266,588 shares of
common stock upon the closing of this offering and such shares of convertible
preferred stock will no longer be authorized, issued or outstanding.
    
 
   
    Upon the closing of this offering, the board of directors will be
authorized, without further stockholder approval, to issue from time to time up
to an aggregate of 5,000,000 shares of preferred stock in one or more series and
to fix or alter the designations, powers, preferences, rights and any
qualifications, limitations or restrictions of the shares of each such series
thereof, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption including sinking fund provisions, redemption
price or prices, liquidation preferences and the number of shares constituting
any series or designations of such series. We have no present plans to issue any
shares of preferred stock. Please see "--Anti-Takeover Effects of Provisions of
Delaware Law and our Certificate of Incorporation and Bylaws" for information
regarding the potential anti-takeover effects of authorized but unissued
preferred stock.

"Management--Benefit Plans" for a discussion of the 1999 Stock Incentive Plan
and "Shares Eligible for Future Sale" for information regarding the number of

COMMON STOCK WARRANT
 
   
    We have an outstanding warrant to purchase 45,000 shares of common stock, at
an exercise price of $7.20. The warrant contains an anti-dilution provision
providing for adjustments of the exercise price and the number of shares
underlying the warrant upon the occurrence of events, including any
recapitalization, reclassification, stock dividend, stock split, stock
combination or similar transaction. This warrant expires on the earlier of the
business day preceding an acquisition or December 31, 2002.
    
 
REGISTRATION RIGHTS
 
   
    As of March 28, 1999, under the terms of an investors' rights agreement
after the closing of this offering the holders of 3,341,841 shares of common
stock and up to 45,000 shares of common stock issuable upon exercise of a
warrant will be entitled to demand registration rights with respect to the
registration of their shares under the Securities Act of 1933. The holders of
50% of shares issued on conversion of the Series B preferred stock and Series C
preferred stock or the holders of 50% of such shares issued on conversion of the
Series D preferred stock have the right to demand that we register their shares
under the Securities Act subject to limitations described in the agreement. We
are not required to file more than two registrations under such demand
registration rights. In addition, after the closing of this offering these
holders will be entitled to piggyback registration rights with respect to the
registration of such shares of common stock under the Securities Act. In the
event that we propose to register any shares of common stock under the
Securities Act either for our account or for the account of other security
holders, the holders of shares having piggyback registration rights are entitled
to receive notice of such registration and to include their shares in any such
registration, subject to limitations described in the agreement. Further, at any
time after we become eligible to file a registration statement on Form S-3, the
holders of 3,341,841 shares of common stock and up to 45,000 shares of common
stock issuable upon exercise of a warrant may require us to file registration
statements under the Securities Act on Form S-3 with respect to their shares of
common stock. These registration rights are subject to conditions and
limitations described in the agreement, among them the right of the underwriters
of an offering to limit the number of shares of common stock held by such
security holders to be included in such registration. We are generally required
to bear all of the expenses of all such registrations, including the reasonable
fees of a single counsel acting on behalf of all selling holders, except
underwriting discounts and selling commissions. Registration of any of the
shares of common stock held by security holders with registration rights would
result in such shares becoming freely tradable without restriction under the
Securities Act immediately upon effectiveness of such registration.
    
 
   
ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE OF
  INCORPORATION AND BYLAWS
    
 
    GENERAL
 
   
    Provisions of Delaware law and our certificate of incorporation and bylaws
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from acquiring, control of us. Such provisions
could limit the price that investors might be willing to pay in the future
    
 
                                       51
<PAGE>
   
for shares of our common stock. These provisions of Delaware law and the
certificate of incorporation and bylaws may also have the effect of discouraging
or preventing transactions involving an actual or threatened change of control
of us, including unsolicited takeover attempts, even though such a transaction
may offer our stockholders the opportunity to sell their stock at a price above
the prevailing market price.
    
 
    DELAWARE TAKEOVER STATUTE
 
   
    We are subject to the "business combination" provisions of Section 203 of
the Delaware General Corporation Law. With limited exceptions, Section 203
prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless:
    
 
    - the transaction is approved by the board of directors prior to the date
      the interested stockholder obtained interested stockholder status;
 
    - upon consummation of the transaction that resulted in the stockholder's
      becoming an interested stockholder, the stockholder owned at least 85% of
      our voting stock outstanding at the time the transaction commenced,
      excluding for purposes of determining the number of shares outstanding
      those shares owned by (a) persons who are directors and also officers and
      (b) employee stock plans in which employee participants do not have the
      right to determine confidentially whether shares held subject to the plan
      will be tendered in a tender or exchange offer; or
 
    - on or subsequent to the date the business combination is approved by the
      board and authorized at an annual or special meeting of stockholders by
      the affirmative vote of at least 66 2/3% of the outstanding voting stock
      that is not owned by the interested stockholder.
 
   
    A "business combination" includes mergers, asset sales and other
transactions resulting in a financial benefit to the interested stockholder.
Subject to exceptions described in the Delaware code, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within three years did own, 15% or more of the corporation's voting stock. This
statute could prohibit or delay the accomplishment of mergers or other takeover
or change in control attempts with respect to us and, accordingly, may
discourage attempts to acquire us.
    
 
   
    In addition, provisions of our certificate of incorporation and bylaws
summarized in the following paragraphs may be deemed to have an anti-takeover
effect and may delay, defer or prevent a tender offer or takeover attempt that a
stockholder might consider in its best interest, including those attempts that
might result in a premium over the market price for the shares held by
stockholders.
    
 
    BOARD OF DIRECTORS VACANCIES
 
    Our bylaws authorize the board of directors to fill vacant directorships or
increase the size of the board of directors. This may deter a stockholder from
removing incumbent directors and simultaneously gaining control of the board of
directors by filling the vacancies created by such removal with its own
nominees.
 
    CLASSIFIED BOARD
 
    Our bylaws provide that our board will be classified into three classes of
directors beginning at the next annual meeting of stockholders. Please see
"Management--Classes of the Board" for more information regarding the classified
board.
 
                                       52
<PAGE>
    STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS
 
    Our certificate of incorporation provides that stockholders may act only at
duly called annual or special meetings of stockholders, not by written consent.
Our bylaws further provide that special meetings of our stockholders may be
called only by the President, Chief Executive Officer or Chairman of the board
of directors or a majority of the board of directors.
 
    ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
     NOMINATIONS
 
   
    Our bylaws provide that stockholders seeking to bring business before our
annual meeting of stockholders, or to nominate candidates for election as
directors at our annual meeting of stockholders, must provide timely notice
thereof in writing. To be timely, a stockholder's notice must be delivered to,
or mailed and received at, our principal executive offices not less than 120
days prior to the first anniversary of the date of notice of annual meeting
provided with respect to the previous year's annual meeting of stockholders;
provided, that if no annual meeting of stockholders was held in the previous
year or the date of the annual meeting of stockholders has been changed to be
more than 30 calendar days earlier than such anniversary, notice by the
stockholder, to be timely, must be received a reasonable time before the
solicitation is made. The bylaws also specify requirements as to the form and
content of a stockholder's notice. These provisions may preclude stockholders
from bringing matters before our annual meeting of stockholders or from making
nominations for directors at our annual meeting of stockholders.
    
 
    AUTHORIZED BUT UNISSUED SHARES
 
   
    Our authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval, subject to
limitations imposed by the Nasdaq National Market. These additional shares may
be utilized for a variety of corporate purposes, including future public
offerings to raise additional capital, corporate acquisitions and employee
benefit plans. The existence of authorized but unissued and unreserved common
stock and preferred stock could render more difficult or discourage an attempt
to obtain control of us by means of a proxy contest, tender offer, merger or
otherwise.
    
 
    Delaware law provides generally that the affirmative vote of a majority of
the shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    Our certificate of incorporation provides that, except to the extent
prohibited by Delaware law, our directors shall not be personally liable to us
or our stockholders for monetary damages for any breach of fiduciary duty as our
directors. Under Delaware law, the directors have a fiduciary duty to us which
is not eliminated by this provision of the certificate and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under Delaware law for breach of the
director's duty of loyalty to us for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or which involve
intentional misconduct, or knowing violations of law, for actions leading to
improper personal benefit to the director, and for payment of dividends or
approval of stock repurchases or redemptions that are prohibited by Delaware
law. This provision does not affect the directors' responsibilities under any
other laws, such as the Federal securities laws or state or Federal
environmental laws.
 
    Section 145 of the Delaware General Corporation Law empowers a corporation
to indemnify its directors and officers and to purchase insurance with respect
to liability arising out of their capacity or status as directors and officers,
provided that this provision shall not eliminate or limit the liability of a
director for the following:
 
    - any breach of the director's duty of loyalty to us or our stockholders;
 
    - acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;
 
   
    - unlawful payments of dividends or unlawful stock purchases or redemptions;
      or
    
 
    - for any transaction from which the director derived an improper personal
      benefit.
 
                                       53
<PAGE>
   
    Delaware law provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under our bylaws, any agreement, a vote of stockholders
or otherwise. The certificate eliminates the personal liability of directors to
the fullest extent permitted by Delaware law. In addition, the certificate
provides that we may fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding by reason of the fact that such person is or was one of our
directors or officers or is or was serving at our request as a director of or
officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses including attorney's fees,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding.
    
 
    We have also entered into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in our
bylaws. We believe that these provisions and agreements are necessary to attract
and retain qualified directors and executive officers. Our bylaws also permit us
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions, regardless of whether
Delaware law would permit indemnification. We have applied for liability
insurance for our officers and directors.
 
    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the certificate of incorporation. We are not aware
of any threatened litigation or proceeding that may result in a claim for such
indemnification.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the common stock is U.S. Stock Transfer
Corporation.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    The market price of our common stock could decline as a result of sales of a
large number of shares of our common stock in the market after this offering, or
the perception that such sales could occur. Such sales also might make it more
difficult for us to sell equity securities in the future at a time and price
that we deem appropriate. After this offering, 8,601,624 shares of common stock
will be outstanding. Of these shares, the 3,150,000 shares being offered in the
offering are freely tradable. This leaves 5,451,624 shares eligible for sale in
the public market as follows:

    In general, under Rule 144, as currently in effect, an affiliate of Rubio's
or a person or persons whose shares are required to be aggregated and who has
beneficially owned shares for at least one year is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of (1)
approximately 86,016 shares immediately after this offering or (2) the average
weekly trading volume in the common stock during the four calendar weeks
preceding the date on which notice of such sale is filed, subject to restriction
under Rule 144. In addition, a person who is not deemed to have been our
affiliate at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years, would
be entitled to sell such shares under Rule 144(k) without regard to the
requirements described above. To the extent that shares were acquired from one
of our affiliates, such person's holding period for the purpose of effecting a
sale under Rule 144 commences on the date of transfer from the affiliate.
    
 
   
    As of the date of this prospectus, options to purchase a total of 571,376
shares of common stock are outstanding, of which 161,134 shares are currently
vested and immediately exercisable. Upon the closing of this offering, we intend
to file a registration statement to register for resale the 1,123,938 shares of
common stock reserved for issuance under our stock option plans. We expect such
registration statement to become effective immediately upon filing. Shares
issued upon the exercise of stock options granted under our stock option plans
will be eligible for resale in the public market from time to time subject to
vesting and, in the case of options held by persons who have signed lock-up
agreements referred to below, the expiration of the lock-up agreements.
    
 
   
    Our directors, officers and stockholders who hold 5,040,718 shares in the
aggregate have entered into lock-up agreements under which they have agreed that
they will not sell, directly or indirectly, any shares of common stock without
the prior written consent of Thomas Weisel Partners LLC for a period of 180 days
from the date of this prospectus. In addition, stockholders who hold 376,932
shares in the aggregate have entered into similar lock-up agreements with us.
    
 
   
    Holders of approximately 3,341,841 shares of common stock and up to 45,000
shares of common stock issuable upon exercise of a warrant, have the right,
subject to conditions and limitations described in the investors rights
agreement, to include their shares in registration statements relating to our
securities. By exercising their registration rights and causing a large number
of shares to be registered and sold in the public market, these holders may
cause the price of the common stock to fall. In addition, any demand to include
such shares in our registration statements could have an adverse effect on our
ability to raise needed capital. Please see "Description of
Securities--Registration Rights" for a description of the registration rights of
our stockholders and "Risk Factors--The large number of shares eligible for
public sale after this offering could cause our stock price to decline" for a

RESERVED SHARES
 
   
    The underwriters, at our request, have reserved for sale at the initial
public offering price up to 94,500 shares of common stock to be sold in this
offering for sale to our employees and other persons designated by us. Michael
Dooling, one of our directors, has expressed interest in acquiring, directly or
through affiliates, 100,000 shares of common stock in this offering at the
initial public offering price. The number of shares available for sale to the
general public will be reduced to the extent that any reserved shares are
purchased. Any reserved shares not purchased in this manner will be offered by
the underwriters on the same basis as the other shares offered in the offering.
    
 
NO SALES OF SIMILAR SECURITIES
 
   
    Our directors, officers and stockholders who hold 5,040,718 shares in the
aggregate, have agreed that they will not offer, sell, or agree to sell,
directly or indirectly, or otherwise dispose of any shares of common stock
without the prior written consent of Thomas Weisel Partners LLC for a period of
180 days from the date of this prospectus.
    
 
   
    In addition, we have agreed that for a period of 180 days after the date of
this prospectus we will not, without the prior written consent of Thomas Weisel
Partners LLC, offer, sell or otherwise dispose of any shares of common stock
except for the shares of common stock offered in the offering, the shares of
common stock issuable upon exercise of outstanding options and warrants.
    
 
INFORMATION REGARDING THOMAS WEISEL PARTNERS LLC
 
   
    Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since December
1998, Thomas Weisel Partners LLC has been named as a lead or co-manager on 24

equity securities. Thomas Weisel Partners LLC does not have any material

NASDAQ NATIONAL MARKET LISTING
 
   
    Prior to this offering, there has been no public market for our common
stock. Consequently, the initial offering price for our common stock will be
determined by negotiations between us, the selling stockholders and
representatives of the underwriters. Some of the factors to be considered in
these negotiations will be our results of operations in recent periods,
estimates of our prospects and the industry in which we compete, an assessment
of our management, the general state of the securities markets at the time of
this offering and the prices of similar securities of generally comparable
companies. We have applied for approval for the quotation of our common stock on
the Nasdaq National Market, under the symbol "RUBO." We cannot assure you,
however, that an active or orderly trading market will develop for our common
stock or that our common stock will trade in the public markets subsequent to
this offering at or above the initial offering price. Please see "Risk
Factors--Our common stock may not develop an active, liquid trading market."
    
 
    The underwriters do not expect to confirm sales of common stock to any
accounts over which they exercise discretionary authority to exceed 5% of the
number of shares being offered under this prospectus.

MARKET STABILIZATION, SHORT POSITIONS AND PENALTY BIDS
 
   
    In order to facilitate this offering, persons participating in this offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of our common stock during and after this offering. Specifically, the
underwriters may over-allot or otherwise create a short position in our common
stock for their own account by selling more shares of common stock than we have
sold to them. The underwriters may elect to cover any short position by
purchasing shares of common stock in the open market or by exercising the
over-allotment option granted to the underwriters. In addition, the underwriters
may stabilize or maintain the price of the common stock by bidding for or
purchasing shares of common stock in the open market and may impose penalty
bids. Under these penalty bids, selling concessions that are allowed to
syndicate members or other broker-dealers participating in this offering are
reclaimed if shares of common stock previously distributed in this offering are
repurchased, usually in order to stabilize the market. The effect of these
transactions may be to stabilize or maintain the market price at a level above
that which might otherwise prevail in the open market. No representation is made
as to the magnitude or effect of any such stabilization or other transactions.
These transactions may be effected on the Nasdaq National Market or otherwise
and may be discontinued at any time after they are commenced.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
Rubio's Restaurants, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Rubio's
Restaurants, Inc. and subsidiary (the "Company") as of December 28, 1997 and
December 27, 1998, and the related consolidated statements of operations,
stockholders' equity (deficit) and of cash flows for each of the three years in
the period ended December 27, 1998. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Rubio's Restaurants, Inc. and
subsidiary as of December 28, 1997 and December 27, 1998, and the results of its
operations and its cash flows for each of the three years in the period ended
December 27, 1998 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
     YEARS ENDED DECEMBER 29, 1996, DECEMBER 28, 1997 AND DECEMBER 27, 1998
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    NATURE OF OPERATIONS--Rubio's Restaurants, Inc. was incorporated in
California in 1985 and reincorporated in Delaware in 1997 (see Note 7). Rubio's
Restaurants, Inc. has a wholly-owned subsidiary which was incorporated in Nevada
in 1997. Rubio's Restaurants, Inc. and its subsidiary (collectively, the
"Company") own and operate a chain of 59 restaurants and three concessions in
Southern California, Nevada and Arizona.
 
    BASIS OF FINANCIAL STATEMENT PRESENTATION--The Company operates and reports
on a 52-53 week fiscal year ending on the Sunday closest to December 31.
 
    ACCOUNTING 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 contingencies at the date of the financial statements and the
reported amounts of revenues and expenses during the reporting period. Actual
results may differ from those estimates.
 
    CASH EQUIVALENTS--Cash equivalents consist of money market instruments
purchased with an original maturity date of three months or less.
 
    INVESTMENTS--The Company's investments are composed primarily of government
and mortgage-backed securities. While it is the Company's general intent to hold
such securities until maturity, management will occasionally sell particular
securities for cash flow purposes. Therefore, pursuant to Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities," the Company's investments are classified as
available-for-sale based upon the Company's intent, and are accounted for at
fair market value (see Note 2). The fair market value of such investments is
determined based on quoted market prices for those investments, and approximated
cost at December 28, 1997. Holding gains on these investments were $75,036 at
December 27, 1998 and are included as other accumulated comprehensive income in
the statements of stockholders' equity. Short-term investments are investments
with original maturities of greater than three months and remaining maturities
of less than one year, or investments that are reasonably expected to be
realized in cash or consumed in operations over the next year (see Note 2).
 
    INVENTORY--Inventory consists of food, beverage and restaurant supplies and
is stated at the lower of cost (first-in, first-out method) or market.
 
    PROPERTY--Property is stated at cost. Depreciation and amortization are
computed using the straight-line method over the estimated useful lives of the
assets or the remaining lease term, whichever is less. The lives for equipment
are 3 - 7 years and for building and leasehold items, 5 - 20 years.
 
    The Company periodically assesses its ability to recover the carrying value
of its long-lived assets. If management concludes that the carrying value will
not be recovered, an impairment write-down is recorded to reduce the asset to
its estimated fair value.
 
   
    In 1997, in accordance with SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets to be Disposed Of," the Company recorded a loss of $386,928 on
long-lived assets where circumstances indicated that the assets were impaired
based on the expected future cash flows of one of the restaurant locations.
Impairment is reviewed at the lowest levels for which there are identifiable
cash flows that are independent of the cash flows of other groups of assets. In
the Company's circumstances,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     YEARS ENDED DECEMBER 29, 1996, DECEMBER 28, 1997 AND DECEMBER 27, 1998
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
such analysis is performed on an individual restaurant basis. The impairment
charge was the difference between the carrying value and the estimated fair
value of the assets. The Company estimated fair values based on sales prices for
comparable assets. The Company will continue to operate this store to the end of
the lease term. The Company did not have any impairment losses in fiscal 1996 or
1998.
    
 
    DEFERRED RENT--Rent expense on operating leases with scheduled or minimum
rent increases is expensed on the straight-line basis over the lease terms.
Deferred rent represents the excess of rent charged to expense over rent payable
under the lease agreement.
 
    UNEARNED USAGE ALLOWANCE--The Company receives payments from the Company's
beverage suppliers under the suppliers' marketing allowance programs and records
such amounts as an unearned usage allowance. The Company recognizes the usage
allowance as a reduction to cost of sales based on the actual quantity purchased
on a monthly basis.
 
    STORE PRE-OPENING EXPENSES--Costs incurred in connection with start-up and
promotion of new store openings are expensed as incurred.
 
    INCOME TAXES--The Company accounts for income taxes in accordance with SFAS
No. 109 "Accounting for Income Taxes" (see Note 5).
 
    STOCK-BASED COMPENSATION--Effective January 1, 1996, the Company adopted
SFAS No. 123, "Accounting for Stock-Based Compensation." SFAS No. 123
encourages, but does not require, companies to record compensation cost for
stock-based employee compensation plans at fair value. The Company has chosen to
continue to account for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees," and related Interpretations.
Accordingly, compensation cost for stock options is measured as the excess, if
any, of the fair market value of the Company's stock at the date of the grant
over the amount an employee must pay to acquire the stock (see Note 7).
 
    CONCENTRATION OF CREDIT RISK--The Company invests its excess cash in money
market accounts and debt securities. The Company has not experienced any
material losses on its cash accounts or other investments.
 
    EARNINGS PER SHARE--In February 1997, the Financial Accounting Standards
Board ("FASB") issued SFAS No. 128, "Earnings Per Share" (EPS), effective for
all financial statements issued after December 15, 1997. SFAS No. 128 requires
dual presentation of "Basic" and "Diluted" EPS by entities with complex capital
structures, replacing "Primary" and "Fully Diluted" EPS under APB Opinion No.
15. Basic EPS excludes dilution and is computed by dividing net income or loss
attributable to common stockholders by the weighted average of common shares
outstanding for the period. Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock (convertible
preferred stock, warrants to purchase common stock and common stock options
using the treasury stock method) were exercised or converted into common stock.
Potential common shares in the diluted EPS computation are excluded where their
effect would be antidilutive. EPS for all periods have been computed in
accordance with SFAS No. 128 (see Note 8).
 
    PRO FORMA NET INCOME PER SHARE--In accordance with SFAS No. 128, pro forma
basic net income per share is computed based on the weighted average of common
shares outstanding during the year,

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
which includes the conversion of 5,262,885 shares of convertible preferred stock
then outstanding into 5,262,885 shares of common stock, and the issuance of
37,677 shares of common stock upon the exercise of certain outstanding warrants
upon the consummation of the Company's planned initial public offering. Pro
forma diluted earnings per share is computed assuming the potential dilution
upon exercise of potential common shares using the treasury stock method, except
for the years where potential dilution is not assumed as the effect would be
antidilutive (see "Earnings Per Share" and Note 8).
    
 
    RECENT ACCOUNTING PRONOUNCEMENTS--In June 1997, the FASB issued SFAS No.
130, "Reporting Comprehensive Income," effective for fiscal years beginning
after December 15, 1997. SFAS No. 130 establishes standards for the reporting
and display of comprehensive income and its components in a full set of general
purpose financial statements. Comprehensive income is defined as the change in
equity of a business enterprise during a period, resulting from transactions and
other events and circumstances from nonowner sources. The Company implemented
SFAS No. 130 for fiscal 1998.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information." SFAS No. 131 requires publicly held
companies to report financial and other information about key revenue-producing
segments of the entity for which such information is available and is utilized
by the chief operating decision maker. Specific information to be reported for
individual segments includes profit or loss, certain revenue and expense items
and total assets. A reconciliation of segment financial information to amounts
reported in the financial statements would be provided. SFAS No. 131 is
effective for the Company in 1998. The Company currently operates as one segment
(see Note 9).
 
    In April 1998, Statement of Position ("SOP") 98-5, "Reporting on the Costs
of Start-Up Activities" was issued by the Accounting Standards Executive
Committee. SOP 98-5 provides guidance on the financial reporting of start-up
costs and organization costs. It requires costs of start-up activities and
organization costs to be expensed as incurred, and is effective for fiscal years
beginning after December 15, 1998. The Company early adopted this SOP for the
fiscal year ended December 28, 1997. The adoption of this SOP did not have a
material effect on the results of operations.
 
    RECLASSIFICATIONS--Certain prior year amounts have been reclassified to
conform with current year presentation.

3.  LONG-TERM DEBT AND CREDIT FACILITIES
 
    CAPITAL EXPANSION LINE--In 1997, the Company had a $3,000,000 capital
expansion line (the "Capital line") with a bank which provided for interest at
1.0% over the bank's referenced rate (8.50% at December 28, 1997). The purpose
of the Capital line was to assist the Company in financing leasehold
improvements and equipment in new restaurant locations. Under the Capital line,
the bank would advance 75% of the invoice amounts, not to exceed $200,000 per
location. Once each restaurant was completed the advances were converted to an
individual term loan. Each individual loan had specific monthly payments of both
principal and interest, commencing one month after conversion. The Capital line
was secured by the Company's assets, including a specific collateral assignment
of Rubio's trademarks and Waiver and Consent Agreement on all new locations
financed. Interest expense for the borrowings under the Capital line was
$219,307, $262,622 and $82,081 for the years ended December 29, 1996, December
28, 1997 and December 27, 1998, respectively. The Capital line contained various
covenants including the maintenance of a minimum amount of tangible net worth
and a debt coverage ratio, and placed certain restrictions on fixed asset
purchases. There was $2,562,074 in total borrowings against the Capital line as
of December 28, 1997, and the Company was in compliance with all related
covenants. There were no additional amounts available upon the expiration of the
Capital line on April 30, 1997. The Company refinanced the remaining borrowings
under the Capital line with the Term Loan in May 1998.

3.  LONG-TERM DEBT AND CREDIT FACILITIES (CONTINUED)
   
    TERM LOAN--In May 1998, the Company entered into a term loan (the "Term
Loan") with another bank to refinance the remaining borrowings under the Capital
line. The Term Loan provides for interest, at the election of the Company at:
(1) adjusted LIBOR plus 4.0% per annum (9.25% at December 27, 1998) or (2) the
greater of the bank reference rate plus 1.5% or the Federal Funds Effective Rate
plus 2.0%. There was $1,856,433 outstanding under the Term Loan as of December
27, 1998. Interest expense was $171,494 under the Term Loan for the year ended
December 27, 1998. There are no additional amounts available to the Company
under the Term Loan. Principal and interest payments are due in quarterly
installments through April 1, 2001 or no later than 90 days after the completion
of an initial public offering, whichever is earlier.
    
 
   
    REVOLVING LINE OF CREDIT--In May 1998, the Company entered into a revolving
line of credit (the "Credit line") in conjunction with the Term Loan, which
provides for interest at the election of the Company, at: (1) adjusted LIBOR
plus 4.0% per annum (9.25% at December 27, 1998) or (2) the greater of the bank
reference rate plus 1.5% or the Federal Funds Effective Rate plus 2.0%.
Principal and interest payments due under the Credit line are payable upon or
before maturity at May 12, 2001. There were no borrowings outstanding against
the Credit line at December 27, 1998.
    
 
    The Term Loan and Credit line contain various covenants including a fixed
charge coverage ratio, minimum interest coverage ratio, and maximum total
leverage ratio, and place certain restrictions on fixed asset purchases. The
Term Loan and Credit line restrict the payment of cash dividends and other stock
redemptions or repurchases, as defined in the agreement, without prior consent
of the lender. Borrowings under the Credit line and the Term Loan are secured by
the Company's assets. The Company was in compliance with all such covenants as
of December 27, 1998.

December 28, 1997 and December 27, 1998:

    The Company has Federal credit carryforwards available to offset future tax
liabilities of $245,301.
 
    The Company has provided a valuation allowance equal to the net deferred tax
asset as of December 28, 1997. The Company eliminated the valuation allowance in
1998 due to management's belief that current year activity made realization of
such benefit more likely than not.

    PREFERRED STOCK PURCHASE WARRANTS
 
       DEFERRED STOCK ISSUE COSTS--In connection with the Series D redeemable
       convertible preferred stock ("Series D Preferred Stock") issuance, the
       Company issued a warrant to purchase up to 27,104 shares (subject to
       adjustment under a formula defined in the warrant) of the Company's

7.  STOCKHOLDERS' EQUITY (DEFICIT)
 
    REINCORPORATION--In 1997, the Company changed its state of incorporation
from California to Delaware. In connection with this change, the outstanding
shares of the Company's no par value common and convertible preferred stock were
converted into and exchanged for an equal number of shares of $.001 par value
common and convertible preferred stock of the Delaware entity. The financial
statements have been restated for all periods presented to reflect this change.
 
    COMMON STOCK--Holders of common stock are entitled to one vote per share.
The rights of the common stock are subject to prior rights of the preferred
stock.
 
   
    CONVERTIBLE PREFERRED STOCK--The Company has Series A convertible preferred
stock outstanding with voting rights. The Series A Preferred Stock is subject to
the Stock Restriction Agreement dated February 1, 1995, as amended and the
Amended and Restated Certificate of Incorporation dated November 18, 1997 (the
"Certificate of Incorporation"). The rights of the Series A stockholders are
junior to the Series B, Series C and Series D stockholders. The Series A
stockholders have the right, at any time, to convert their shares into common
stock on a 1 for 1 basis, subject to adjustment as defined in the Certificate of
Incorporation. Should a liquidation take place, preferred stockholders have
preferential rights to distributions equal to $2.00 per share. Conversion
becomes automatic in the event: (1) the Company initiates a public offering with
aggregate net proceeds of $15 million, or (2) the majority of the holders of the
then outstanding preferred stock elect to convert their shares into common
stock. The holders have certain registration rights.
    
 
    COMMON STOCK WARRANT--In connection with the Series B convertible redeemable
preferred stock issuance (see Note 6), the Company issued a warrant to purchase
up to 50,000 shares (subject to adjustment under a formula defined in the
warrant) of the Company's common stock. The warrant is exercisable under certain
conditions specified in the warrant. The warrant term extends until the earlier
of February 2, 2000 or the effective date of an initial public offering of
equity securities. The exercise price is $3.20511 per share. The total fair
value of the warrant upon date of issuance was not material.
 
    1995 STOCK OPTION/STOCK ISSUANCE PLAN--On May 30, 1996, the stockholders of
the Company approved the 1995 Stock Option/Stock Issuance Plan (the "Plan"). The
Plan supersedes and incorporates all options outstanding under the 1993 Stock
Option Plan. The Plan provides for the issuance of incentive and nonstatutory
options and for the purchase of common stock for eligible individuals. The Board
of Directors administers the Plan. The stock issuable under the Plan is shares
of authorized but unissued or reacquired common stock. The maximum number of
shares of common stock which may be issued over the term of the Plan may not
exceed 306,147 shares. The total number of shares authorized, as well as shares
subject to outstanding options, will be adjusted in the event of certain changes
to the Company's capital structure, such as stock splits or dividends or other
recapitalization. In no event will any adjustment be made in connection with the
conversion of one or more outstanding shares of the Company's preferred stock
into shares of common stock.
 
   
    The Plan is divided into two separate programs: (1) the option grant program
and (2) the stock issuance program. Participation in the Plan is limited to
employees, non-employee directors and consultants of the Company. The option
exercise price per share is fixed by the Plan administrator in accordance with
the following provisions: (1) the exercise price shall not be less than 85% of
the fair market value per share of the common stock on the date of grant, except
for incentive stock options, where the exercise price shall not be less than
100% of the fair market value of the common stock on

the date of grant, and (2) if the person to whom the option is granted is a 10%
stockholder, then the exercise price per share shall not be less than 110% of
the fair market value per share of the common stock on the option grant date.
The purchase price per share for stock issuances is determined by the Plan
administrator and must be at least 85% of the fair market value of a share of
common stock at the time of issuance.
    
 
    Each option granted under the Plan has a maximum term of either five or ten
years (depending on stock ownership) and will be subject to earlier termination
in the event of the optionee's termination of service.
 
    1998 STOCK OPTION/STOCK ISSUANCE PLAN--On March 27, 1998, the stockholders
of the Company approved the 1998 Stock Option/Stock Issuance Plan (the "1998
Plan"). The 1998 Plan provides for the issuance of incentive and nonstatutory
options and for the purchase of common stock for eligible individuals. The Board
of Directors administers the 1998 Plan. The stock issuable under the 1998 Plan
is shares of authorized but unissued or reacquired common stock. The number of
shares of common stock which may be issued over the term of the 1998 Plan,
including the authorization of an additional 200,000 shares for issuance on
March 18, 1999, may not exceed 368,853 shares. The total number of shares
authorized, as well as shares subject to outstanding options, will be adjusted
in the event of certain changes to the Company's capital structure, such as
stock splits or dividends or other recapitalization. In no event will any
adjustment be made in connection with the conversion of one or more outstanding
shares of the Company's preferred stock into shares of common stock.
 
   
    The 1998 Plan is divided into two separate programs: (1) the option grant
program and (2) the stock issuance program. Participation in the 1998 Plan is
limited to employees, non-employee directors and consultants of the Company. The
option exercise price per share is fixed by the 1998 Plan administrator in
accordance with the following provisions: (1) the exercise price shall not be
less than 85% of the fair market value per share of the common stock on the date
of grant, except for incentive stock options, where the exercise price shall not
be less than 100% of the fair market value of the common stock on the date of
grant, and (2) if the person to whom the option is granted is a 10% stockholder,
then the exercise price per share shall not be less than 110% of the fair market
value per share of the common stock on the option grant date. The purchase price
per share for stock issuances is determined by the 1998 Plan administrator and
must be at least 85% of the fair market value of a share of common stock at the
time of issuance. The purchase price per share for stock issuances to a 10%
stockholder shall not be less than 110% of the fair market at the time of
issuance.
    
 
    Each option granted under the 1998 Plan has a maximum term of either five or
ten years (depending on stock ownership) and will be subject to earlier
termination in the event of the optionee's termination of service.
 
    1999 STOCK INCENTIVE PLAN--On March 18, 1999 and March 24, 1999, the Board
of Directors and the stockholders, respectively, of the Company approved the
1999 Stock Incentive Plan (the "1999 Plan"). The 1999 Plan will be effective
upon the execution of the underwriting agreement and pricing of the common stock
with respect to the Company's initial public offering. All outstanding options
under the 1993 Stock Option Plan, the 1995 Stock Option/Stock Issuance Plan and
the 1998 Stock Option/Stock Issuance Plan (collectively, the "predecessor
plans") will be incorporated into the 1999 Plan upon the effective date, and no
further grants will be made under the predecessor plans. Except as otherwise

7.  STOCKHOLDERS' EQUITY (DEFICIT) (CONTINUED)
noted below, the options previously granted under the predecessor plans will
have substantially the same terms as in effect for new grants made under the
1999 Plan.
 
   
    The stock issuable under the 1999 Plan shall be shares of authorized but
unissued or reacquired common stock, including shares repurchased by the Company
on the open market. A total of 1,123,938 shares of common stock have been
authorized for issuance under the 1999 Plan, which includes the shares subject
to outstanding options under the predecessor plans. As of December 27, 1998,
145,860 options were available for grant under the predecessor plans. The number
of shares of common stock reserved for issuance under the 1999 Plan will
automatically increase on the first trading day in January each year, beginning
in calendar year 2000. The increase will be equal to 3% of the total number of
shares of common stock outstanding as of the last trading day in December of the
preceding year, not to exceed 450,000 shares in any given year. In addition, no
participant in the 1999 Plan may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances for more than
500,000 shares of common stock in the aggregate per calendar year. Each option
shall have a maximum term of either five or ten years, depending on the related
program, and will be subject to earlier termination in the event of the
optionee's termination of service.
    
 
   
    The 1999 Plan is divided into five separate components; (1) the
discretionary option grant program, (2) the stock issuance program, (3) the
salary investment option grant program, (4) the automatic option grant program
and (5) the director fee option grant program.
    
 
   
    The discretionary option grant and stock issuance programs provide for the
issuance of incentive and nonstatutory options for eligible employees. The
option exercise price per share is fixed by the 1999 Plan administrator in
accordance with the following provisions: (1) the exercise price shall not be
less than 100% of the fair market value per share of the common stock on the
date of grant, and (2) if the person to whom the option is granted is a 10%
stockholder, then the exercise price per share shall not be less than 110% of
the fair market value per share of the common stock on the date of grant. The
purchase price for stock issuances is determined by the 1999 Plan administrator
and shall not be less than 100% of the fair market value of a share of common
stock at the time of issuance. Each option shall be exercisable at such time or
times, during such period and for such number of shares as shall be determined
by the 1999 Plan administrator as set forth in the related individual option
agreements.
    
 
    The salary investment option grant program, if activated, would be available
to executive officers and other highly compensated eligible employees. The
participants may elect, prior to the start of a calendar year, to reduce their
base salary by a specific dollar amount not less than $10,000 nor more than

    1999 EMPLOYEE STOCK PURCHASE PLAN--On March 18, 1999 and March 24, 1999, the
Board of Directors and stockholders, respectively, approved the 1999 Employee
Stock Purchase Plan ("ESPP"). The ESPP will be effective upon the execution of
the underwriting agreement and pricing of the common stock with respect to the
Company's initial public offering. The ESPP allows eligible employees, as
specified in the ESPP, to purchase shares of common stock in semi-annual
intervals through payroll deductions under this plan. The accumulated payroll
deductions will be applied to the purchase of shares on the employee's behalf at
a price per share equal to 85% of the lower of (1) the fair market value of the
Company's common stock at the date of entry into the current offering period or
(2) the fair market value on the purchase date. An initial reserve of 200,000
shares of common stock has been authorized for issuance under the ESPP. The
Board of Directors may alter, suspend or discontinue the ESPP. However, certain
amendments to the ESPP may require stockholder approval.

    The Company applies APB Opinion No. 25 and related interpretations in
accounting for its employee stock option plans (see Note 1). Under APB Opinion
No. 25, the Company will record compensation expense resulting from the
difference between the respective grant price per share and the estimated fair
market value of the common stock at the dates of grant. Total deferred
compensation for fiscal 1998 grants was $300,540, and will be recorded ratably
over the vesting period of the respective options. For the year ended December
27, 1998 the Company recorded $22,881 of deferred compensation expense
associated with these option grants.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
    
 
   
                   FOR THE THREE MONTHS ENDED MARCH 28, 1999
    
 
   
1.  BASIS OF PRESENTATION
    
 
   
    The accompanying consolidated financial information has been prepared by
Rubio's Restaurants, Inc. and its wholly-owned subsidiary (collectively, the
"Company") without audit, in accordance with the instructions to Form 10-Q and
therefore does not include all information and footnotes necessary for a fair
presentation of financial position, results of operations and cash flows in
accordance with generally accepted accounting principles.
    
 
   
    UNAUDITED INTERIM FINANCIAL DATA--In the opinion of management, the
unaudited consolidated financial statements for the interim periods presented
reflect all adjustments, consisting of only normal recurring accruals, necessary
for a fair presentation of the financial position and results of operations as
of and for such periods indicated. These consolidated financial statements and
notes thereto should be read in conjunction with the consolidated financial
statements and notes thereto included elsewhere in this prospectus for the year
ended December 27, 1998. Results for the interim periods presented herein are
not necessarily indicative of results which may be reported for any other
interim period or for the entire fiscal year.
    
 
   
    PRO FORMA NET INCOME PER SHARE--In accordance with Statement of Financial
Accounting Standards ("SFAS") No. 128, "Earnings Per Share" (EPS), pro forma
basic net income per share is computed based on the weighted average of common
shares outstanding during the year, which includes the conversion of all
convertible preferred stock and the issuance of shares of common stock upon the
exercise of certain outstanding warrants (see "Unaudited Pro Forma Stockholders'
Equity") upon the consummation of the Company's planned initial public offering.
Pro forma diluted earnings per share is computed assuming the potential dilution
upon exercise of potential common shares using the treasury stock method, except
for the years where potential dilution is not assumed as the effect would be
antidilutive (see Note 4).
    
 
   
    UNAUDITED PRO FORMA STOCKHOLDERS' EQUITY--On March 18, 1999, the Company's
Board of Directors approved an increase in the authorized shares of common stock
to 75,000,000 and authorized 5,000,000 shares of undesignated preferred stock.
The change in authorized shares will be effective upon the closing of the
company's planned initial public offering. Consolidated stockholders' equity as
of March 28, 1999 has been shown on a pro forma basis, assuming conversion of
5,262,885 shares of convertible preferred stock then outstanding into 5,262,885
shares of common stock, and the issuance of 37,677 shares of common stock upon
the exercise of certain outstanding warrants. The unaudited pro forma
consolidated balance sheet as of March 28, 1999 and pro forma net income per
share (see "Pro Forma Net Income Per Share"), reflect this conversion.

3.  LONG-TERM DEBT AND CREDIT FACILITIES
    
 
   
    TERM LOAN--On April 1, 1999, the Company amended the Revolving Credit and
Term Loan Agreement (the "Term Loan"). The amendment eliminated the provision to
prepay the Term Loan including interest not later than 90 days after the
completion of an initial public offering. The amendment also provides for a
decrease in the interest rate, at the election of the Company, to a bank
reference rate plus 0.75% or an adjusted LIBOR plus 3.0% per annum. There was
$1,670,790 outstanding under the Term Loan as of March 28, 1999. Interest
expense was $55,517 under the Term Loan for the three months ended March 28,
1999. There are no additional amounts available to the Company under the Term
Loan. Principal and interest payments are due in quarterly installments through
April 1, 2001.
    
 
   
    REVOLVING LINE OF CREDIT--On April 1, 1999, the Company amended the
Revolving Credit and Term Loan Agreement (the "Credit line"). The amendment
decreased the rate for any unused commitment fees to 0.375%. In addition, the
amendment provides for a decrease in the interest rate, at the election of the
Company, to a bank reference rate plus 0.75% or an adjusted LIBOR plus 3.0% per
annum. Principal and interest payments due under the Credit line are payable
before or upon maturity at May 12, 2001. There were no borrowings outstanding
against the Credit line at March 28, 1999. On April 9, 1999, the Company

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
   
    Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
specified circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933.
    
 
    As permitted by the Delaware General Corporation Law, the Registrant's
Second Restated Certificate of Incorporation includes a provision that
eliminates the personal liability of our directors for monetary damages for
breach of fiduciary duty as a director, except for liability (1) for any breach
of the director's duty of loyalty to the Registrant or our stockholders, (2) for
acts or omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (3) under section 174 of the Delaware General
Corporation Law (regarding unlawful dividends and stock purchases), or (4) for
any transaction from which the director derived an improper personal benefit.
 
   
    As permitted by the Delaware General Corporation Law, the bylaws of the
Registrant provide that (1) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law, subject to very limited exceptions, (2) the Registrant may
indemnify its other employees and agents as set forth in the Delaware General
Corporation Law, (3) the Registrant is required to advance expenses, as
incurred, to its directors and executive officers in connection with a legal
proceeding to the fullest extent permitted by the Delaware General Corporation
Law, subject to very limited exceptions and (4) the rights conferred in the
bylaws are not exclusive.
    
 
    The Registrant has entered into indemnification agreements with each of its
directors and executive officers to give such directors and officers additional
contractual assurances regarding the scope of the indemnification set forth in
the Registrant's Amended and Restated Certificate of Incorporation and to
provide additional procedural protections. At present, there is no pending
litigation or proceeding involving a director, officer or employee of the
Registrant regarding which indemnification is sought, nor is the Registrant
aware of any threatened litigation that may result in claims for
indemnification.
 
                                      II-1
<PAGE>
    Reference is also made to Section 8 of the Underwriting Agreement, which
provides for the indemnification of officers, directors and controlling persons
of the Registrant against certain liabilities. The indemnification provision in
the Registrant's Certificate of Incorporation, bylaws and the indemnification
agreements entered into between the Registrant and each of its directors and
executive officers may be sufficiently broad to permit indemnification of the
Registrant's directors and executive officers for liabilities arising under the
Securities Act of 1933.
 
    The Registrant has applied for liability insurance for its officers and
directors.
 
    Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere in this prospectus:

ITEM 17. UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities Exchange Commission such
indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
    The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the Registrant pursuant to Rule 424 (b)(1) or
    (4) or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

and selling up to 186,748 shares of common stock and each Selling Stockholder

     The Company has filed with the Securities and Exchange Commission (the
"COMMISSION") a registration statement on Form S-1 (file no. 333-75087),
including a prospectus, relating to the Shares.  The registration statement as
amended at the time it becomes effective, including the information (if any)
deemed to be part of the registration statement at the time of effectiveness
pursuant to Rule 430A under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), is hereinafter referred to as the "REGISTRATION STATEMENT";
the prospectus in the form first used to confirm sales of Shares is hereinafter
referred to as the "PROSPECTUS".  If the Company has filed a registration
statement to register additional shares of Common Stock pursuant to Rule 462(b)
under the Securities Act (the "RULE 462 REGISTRATION STATEMENT"), then any
reference herein to the term "REGISTRATION STATEMENT" shall be deemed to include
such Rule 462 Registration Statement.  All references in this Agreement to the
Registration Statement, the Rule 462 Registration Statement, a preliminary
prospectus, the Prospectus, or any amendments or supplements to any of the
foregoing, shall include any copy thereof filed with the Commission pursuant to
its Electronic Data Gathering, Analysis and Retrieval System ("EDGAR").

     1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company 
represents and warrants to and agrees with each of the Underwriters that:

          (a)  EFFECTIVE REGISTRATION STATEMENT.  The Registration Statement 
has become effective; no stop order suspending the effectiveness of the 
Registration Statement is in effect, and no proceedings for such purpose are 
pending before or, to the best knowledge of the Company, threatened by the 
Commission.

          (b)  CONTENTS OF REGISTRATION STATEMENT.  (i) The Registration 
Statement, when it became effective, did not contain and, as amended or 
supplemented, if applicable, will not contain any untrue statement of a 
material fact or omit to state a material fact required to be stated therein 
or necessary to make the statements therein not misleading, (ii) the 
Registration Statement and the Prospectus comply and, as amended or 
supplemented, if applicable, will comply in all material respects with the 
Securities Act and the applicable rules and regulations of the Commission 
thereunder and (iii) the Prospectus does not contain and, as amended or 
supplemented, if applicable, will not contain any untrue statement of a 
material fact or omit to state a material fact necessary to make the 
statements therein, in the light of the circumstances under which they were 
made, not misleading, except that the representations and warranties set 
forth in this paragraph do not apply to statements or omissions in the 
Registration Statement or the Prospectus based upon information relating to 
any Underwriter furnished to the Company in writing by such Underwriter 
through you expressly for use therein.

          (c)  DUE INCORPORATION.  The Company has been duly incorporated, is 
validly existing as a corporation in good standing under the laws of the 
jurisdiction of its incorporation, has the corporate power and authority to 
own its property and to conduct its business as described in the Prospectus 
and is duly qualified to transact business and is in good standing in each 
jurisdiction in which the conduct of its business or its ownership or leasing 
of property requires such qualification, except to the extent that the 
failure to be so qualified or be in good standing would not have a 


                                        2
<PAGE>

material adverse effect on the Company and Subsidiary (as defined below), 
taken as a whole (a "MATERIAL ADVERSE EFFECT").

          (d)  SUBSIDIARY.  The Company has one subsidiary, Rubio's Restaurants
of Nevada, Inc., a Nevada corporation ("SUBSIDIARY").  Subsidiary has been duly
incorporated, is validly existing as a corporation in good standing under the
laws of the jurisdiction of its incorporation, has the corporate power and
authority to own its property and to conduct its business and is duly qualified
to transact business and is in good standing in each jurisdiction in which the
conduct of its business or its ownership or leasing of property requires such
qualification, except to the extent that the failure to be so qualified or be in
good standing would not have a Material Adverse Effect.  All of the issued
shares of capital stock of Subsidiary have been duly and validly authorized and
issued, are fully paid and non-assessable and are owned directly by the Company,
free and clear of all liens, encumbrances, equities or claims.

          (e)  UNDERWRITING AGREEMENT.  This Agreement has been duly authorized,
executed and delivered by the Company, and is a valid and binding agreement of
the Company, enforceable in accordance with its terms, except as rights to
indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

          (f)  DESCRIPTION OF CAPITAL STOCK.  The authorized capital stock of 
the Company conforms as to legal matters to the description thereof contained 
in the Prospectus.  There are no outstanding subscriptions, rights warrants, 
options, calls, convertible securities, commitments of sale or liens granted 
or issued by the Company or Subsidiary relating to or entitling any person to 
purchase or otherwise to acquire any shares of the capital stock of the 
Company or Subsidiary, except as otherwise disclosed in the Registration 
Statement.

          (g)  AUTHORIZED STOCK.  The shares of Common Stock (including the 
Shares to be sold by the Selling Stockholders) outstanding prior to the 
issuance of the Shares to be sold by the Company and the Selling Stockholders 
 have been duly authorized and are validly issued, fully paid and 
non-assessable.

          (h)  VALIDLY ISSUED SHARES.  The Shares to be sold by the Company 
and the Selling Stockholders have been duly authorized and, when issued and 
delivered in accordance with the terms of this Agreement, will be validly 
issued, fully paid and non-assessable, and the issuance of such Shares will 
not be subject to any preemptive or similar rights.

          (i)  NO CONFLICT.  The execution and delivery by the Company of, 
and the performance by the Company of its obligations under, this Agreement 
will not contravene any provision of applicable law or the certificate of 
incorporation or by-laws of the Company or any agreement or other instrument 
binding upon the Company or Subsidiary that is material to the Company and 
Subsidiary, taken as a whole, or any judgment, order or decree of any 
governmental body, agency or court having jurisdiction over the Company or 
Subsidiary, and no consent, approval, authorization or order of, or 
qualification with, any governmental 


                                        3
<PAGE>

body or agency is required for the performance by the Company of its 
obligations under this Agreement, except such as may be required by the 
securities or Blue Sky laws of the various states in connection with the 
offer and sale of the Shares.

          (j)  NO MATERIAL ADVERSE CHANGE.  There has not occurred any 
material adverse change, and no facts or circumstances have come to the 
Company's or Subsidiary's attention which could reasonably be expected to 
result in a material adverse change in the condition, financial or otherwise, 
or in the earnings, business or operations of the Company and Subsidiary, 
taken as a whole, from that set forth in the Prospectus (exclusive of any 
amendments or supplements thereto subsequent to the date of this Agreement).

          (k)  LEGAL PROCEEDINGS; EXHIBITS.  There are no legal or 
governmental proceedings pending or, to the best knowledge of the Company, 
threatened to which the Company or Subsidiary is a party or to which any of 
the properties of the Company or Subsidiary is subject that are required to 
be described in the Registration Statement or the Prospectus and are not so 
described or any statutes, regulations, contracts or other documents that are 
required to be described in the Registration Statement or the Prospectus or 
to be filed as exhibits to the Registration Statement that are not described 
or filed as required.

          (l)  COMPLIANCE WITH SECURITIES ACT.  Each preliminary prospectus 
filed as part of the Registration Statement as originally filed or as part of 
any amendment thereto, or filed pursuant to Rule 424 under the Securities 
Act, complied when so filed in all material respects with the Securities Act 
and the applicable rules and regulations of the Commission thereunder.

          (m)  NOT AN INVESTMENT COMPANY.  The Company is not and, after 
giving effect to the offering and sale of the Shares and the application of 
the proceeds thereof as described in the Prospectus, will not be an

all permits, licenses or other approvals required of them under applicable 
Environmental Laws to conduct their respective businesses and (iii) are in 
compliance with all terms and conditions of any such permit, license or 
approval, except where such noncompliance with Environmental Laws, failure to 
receive required permits, licenses or other approvals or failure to comply 
with the terms and conditions of such permits, licenses or approvals would 
not, individually or in the aggregate, have a Material Adverse Effect.


                                        4
<PAGE>

          (o)  NO ENVIRONMENTAL COSTS.  There are no costs or liabilities 
associated with Environmental Laws (including, without limitation, any 
capital or operating expenditures required for clean-up, closure of 
properties or compliance with Environmental Laws or any permit, license or 
approval, any related constraints on operating activities and any potential 
liabilities to third parties) which would, individually or in the aggregate, 
have a Material Adverse Effect.

          (p)  NO REGISTRATION RIGHTS.  There are no contracts, agreements or 
understandings between the Company and any person granting such person the 
right to require the Company to file a registration statement under the 
Securities Act with respect to any securities of the Company or to require 
the Company to include such securities with the Shares registered pursuant to 
the Registration Statement other than as described in the Registration 
Statement and as have been waived in writing in connection with the offering 
contemplated hereby.

          (q)  CUBAN BUSINESS STATUTE.  The Company has complied with all 
provisions of Section 517.075, Florida Statutes relating to doing business 
with the Government of Cuba or with any person or affiliate located in Cuba.

          (r)  ABSENCE OF MATERIAL CHANGES.  Subsequent to the respective 
dates as of which information is given in the Registration Statement and the 
Prospectus (exclusive of amendments or supplements thereto subsequent to the 
date of this Agreement), (1) the Company and Subsidiary have not incurred any 
material liability or obligation, direct or contingent, nor entered into any 
material transaction not in the ordinary course of business; (2) the Company 
has not purchased any of its outstanding capital stock, nor declared, paid or 
otherwise made any dividend or distribution of any kind on its capital stock 
other than ordinary and customary dividends; and (3) there has not been any 
material change, and no facts or circumstances have come to the Company's or 
Subsidiary's attention which could reasonably be expected to result in a 
material adverse change, in the capital stock, short-term debt or long-term 
debt of the Company and Subsidiary, except in each case as described in the 
Prospectus.

          (s)  GOOD TITLE TO PROPERTIES.  The Company and Subsidiary have 
good and marketable title in fee simple to all real property and good and 
marketable title to all personal property owned by them which is material to 
the business of the Company and Subsidiary, in each case free and clear of 
all liens, encumbrances and defects except such as are described in the 
Prospectus or such as do not materially affect the value of such property and 
do not interfere with the use made and proposed to be made of such property 
by the Company and Subsidiary; and any real property and buildings held under 
lease by the Company and Subsidiary are held by them under valid and 
subsisting leases which are enforceable against the Company and, to the 
Company's knowledge, the other parties thereto, with such exceptions as are 
not material and do not interfere with the use made and proposed to be made 
of such property and buildings by the Company and Subsidiary.

          (t)  INTELLECTUAL PROPERTY RIGHTS.  The Company and Subsidiary own 
or possess valid rights to, or can acquire on reasonable terms, all material 
patents, patent rights, licenses, 


                                        5
<PAGE>

inventions, copyrights, know-how (including trade secrets and other 
unpatented and/or unpatentable proprietary or confidential information, 
systems or procedures), trademarks, service marks and trade names currently 
employed by them in connection with the business now operated by them, and 
neither the Company nor Subsidiary has received any notice of infringement of 
or conflict with asserted rights of others with respect to any of the 
foregoing which, individually or in the aggregate, if the subject of an 
unfavorable decision, ruling or finding, would have a Material Adverse Effect.

          (u)  LABOR.  (i) No material labor dispute with the employees of 
the Company or Subsidiary exists, or, to the knowledge of the Company, is 
imminent; (ii) the Company is not aware of any existing, threatened or 
imminent labor disturbance by the employees of any of its principal 
suppliers, manufacturers or contractors that could have a Material Adverse 
Effect; and (iii) to the Company's knowledge, neither the Company nor 
Subsidiary is in violation or has violated the requirements of the U.S. 
Immigration and Naturalization Service with respect to the Company's 
employment practices, except for such violations that would not have a 
Material Adverse Effect.

          (v)  INSURANCE.  The Company and Subsidiary are insured by the 
insurers of recognized financial responsibility against such losses and risks 
and in such amounts as are prudent and customary in the businesses in which 
they are engaged; and neither the Company nor Subsidiary has any reason to 
believe that it will not be able to renew its existing insurance coverage as 
and when such coverage expires or to obtain similar coverage from similar 
insurers as may be necessary to continue its business at a cost that would 
not have a Material Adverse Effect.

          (w)  GOVERNMENTAL PERMITS.  The Company and Subsidiary possess all 
certificates, authorizations and permits issued by the appropriate federal, 
state or foreign regulatory authorities material to the conduct of their 
respective business, and neither the Company nor Subsidiary has received any 
notice of proceedings relating to the revocation or modification of any such 
certificate, authorization or permit which, individually or in the aggregate, 
if the subject of an unfavorable decision, ruling or finding, would have a 
Material Adverse Effect.

          (x)  ACCOUNTING CONTROLS.  The Company and Subsidiary maintain a 
system of internal accounting controls sufficient to provide reasonable 
assurance that (1) transactions are executed in accordance with management's 
general or specific authorizations; (2) transactions are recorded as 
necessary to permit preparation of financial statements in conformity with 
generally accepted accounting principles and to maintain asset 
accountability; (3) access to assets is permitted only in accordance with 
management's general or specific authorization; and (4) the recorded 
accountability for assets is compared with the existing assets at reasonable 
intervals and appropriate action is taken with respect to any differences.

          (y)  YEAR 2000 COMPLIANCE.  The Company has reviewed its operations 
and that of Subsidiary and any third parties with which the Company or 
Subsidiary has a material relationship to evaluate the extent to which the 
business or operations of the Company or Subsidiary will be affected by the 
Year 2000 Problem (defined below).  As a result of such review, the Company 
has no reason to believe, and does not believe, that the Year 2000 Problem 
will have a Material Adverse 


                                        6
<PAGE>

Effect, or result in any material loss or interference with the Company's 
business or operations.  The "YEAR 2000 PROBLEM" as used herein means any 
significant risk that computer hardware or software used in the receipt, 
transmission, processing, manipulation, storage, retrieval, retransmission or 
other utilization of data or in the operation of mechanical or electrical 
systems of any kind will not, in the case of dates or time periods occurring 
after December 31, 1999, function at least as effectively as in the case of 
dates or time periods occurring prior to January 1, 2000.

          (z)  COMPLIANCE WITH FOOD AND BEVERAGE LAWS.  To the Company's 
knowledge, the Company and Subsidiary are conducting their business in 
compliance with the Fair Labor Standards Act, the rules and regulations of 
the federal Food and Drug Administration, and all applicable federal, state 
and local laws, rules and regulations of the jurisdictions in which it is 
conducting business, including, without limitation, all applicable local, 
state and federal laws and regulations governing health, sanitation, safety, 
the purchase and sale of alcoholic beverages (including, but not limited to, 
liquor licenses, "tied house" statutes and "dram shop" statutes), zoning and 
land use, except where the failure to be so in compliance would not have a 
Material Adverse Effect.

          (aa) TAXES.  All material tax returns required to be filed by the
Company and Subsidiary in any jurisdiction have been filed, other than those
filings being contested in good faith, and all material taxes, including
withholding taxes, penalties and interest, assessments, fees and other charges
due pursuant to such returns or pursuant to any assessment received by the
Company or Subsidiary have been paid, other than those being contested in good
faith or for which adequate reserves have been provided.

     2.   REPRESENTATIONS AND WARRANTIES OF THE SELLING STOCKHOLDERS.  Each 
of the Selling Stockholders severally and not jointly, represents and 
warrants to and agrees with each of the Underwriters that:

          (a)  DUE AUTHORIZATION.  This Agreement has been duly authorized,

Selling Stockholder pursuant to this Agreement will pass title to such Shares 
free and clear of any "Adverse Claims" as defined in Section 8-102(a)(1) of 
the California Commercial Code (assuming that the transferee has purchased 
the Shares without notice of any such "Adverse Claims").

          (g)  NO REGISTRATION RIGHTS.  Such Selling Stockholder does not 
have any registration or other similar rights to have any equity or debt 
securities registered for sale by the Company under the Registration

          (i)  DISCLOSURE IN REGISTRATION STATEMENT.  Such Selling 
Stockholder has no reason to believe that (i) the Registration Statement, 
when it became effective, contained and, as amended or supplemented, if 
applicable, will not contain, any untrue statement of a material fact or 
omitted to state a material fact required to be stated therein or necessary 
to make the statements therein not misleading, and (ii) the Prospectus 
contained and, as amended or supplemented, if applicable, will not contain, 
any untrue statement of a material fact or omitted to state a material fact 
necessary to make the statements therein, in the light of the circumstances 
under which they were made, not misleading, except that the representations 
and warranties set forth in this paragraph 2(i) do not apply to statements or 
omissions in the Registration Statement or the Prospectus based upon 
information relating to any Underwriter furnished to the Company in writing 
by such Underwriter through you expressly for use therein.

          (j)  NOTIFICATION OF CHANGES.  At any time during the period 
described in Section 5(c), if there is any change in the information referred 
to in Section 2(i) which comes to the attention of the Selling Stockholder, 
such Selling Stockholder will immediately notify you of such change.

          (k)  NO ADVERSE INFORMATION.  Such Selling Stockholder is not 
prompted to sell any of the Shares hereunder by any material adverse 
information concerning the Company which is not set forth in the Registration 
Statement and the Prospectus.

     3.   PURCHASE AND SALE AGREEMENTS.

          (a)  FIRM SHARES.  Each Seller, severally and not jointly, hereby 
agrees to sell to the several Underwriters, and each Underwriter, upon the 
basis of the representations and warranties herein contained, but subject to 
the conditions hereinafter stated, agrees, severally and not jointly, to 
purchase from such Seller at $______ a share (the "PURCHASE PRICE") the 
number of Firm Shares (subject to such adjustments to eliminate fractional 
shares as you may determine) that bears the same proportion to the number of 
Firm Shares to be sold by such Seller as the number of Firm Shares set forth 
in SCHEDULE A hereto opposite the name of such Underwriter bears to the total 
number of Firm Shares.

          (b)  ADDITIONAL SHARES.  On the basis of the representations and 
warranties contained in this Agreement, and subject to its terms and 
conditions, the Company hereby agrees, and the Selling Stockholders severally 
and not jointly hereby agree, to sell to the Underwriters the Additional 
Shares, and the Underwriters shall have a one-time right to purchase, 
severally and not jointly, up to 472,500 Additional Shares, with the Company 
issuing and selling up to 186,748 shares of Common Stock and each Selling 
Stockholder selling up to the number of shares of Common Stock set forth 
opposite the name of each such Selling Stockholder on SCHEDULE B hereto; in 
each case at the Purchase Price. In the event that the Underwriters elect to 
purchase less than all of the Additional Shares, the number of Additional 
Shares to be purchased from the Company and each Selling Stockholder shall be 
determined by multiplying the maximum number of Additional Shares to be sold 
by the Company and each Selling Stockholder as set forth on SCHEDULE B hereto 
by a 


                                        9
<PAGE>

fraction, the numerator of which is the actual aggregate number of Additional 
Shares being purchased by the Underwriters, and the denominator of which is 
472,500.  If you, on behalf of the Underwriters, elect to exercise such 
option, you shall so notify the Company and such Selling Stockholders in 
writing not later than thirty (30) days after the date of this Agreement, 
which notice shall specify the number of Additional Shares to be purchased by 
the Underwriters and the date on which such shares are to be purchased.  Such 
date may be the same as the Closing Date (as defined below) but not earlier 
than the Closing Date nor later than ten (10) business days after the date of 
such notice.  Additional Shares may be purchased as provided in Section 3 
hereof solely for the purpose of covering over-allotments made in connection 
with the offering of the Firm Shares.  If any Additional Shares are to be 
purchased, each Underwriter agrees, severally and not jointly, to purchase 
the number of Additional Shares (subject to such adjustments to eliminate 
fractional shares as you may determine) that bears the same proportion to the 
total number of Additional Shares to be purchased as the number of Firm 
Shares set forth in SCHEDULE A hereto opposite the name of such Underwriter 
bears to the total number of Firm Shares.

          (c)  MARKET STANDOFF PROVISION.  Each Seller hereby agrees that, 
without the prior written consent of Thomas Weisel Partners LLC (which 
consent may be withheld in its sole discretion), it will not, during the 
period ending 180 days after the date of the Prospectus, (i) offer, pledge, 
sell, contract to sell, sell any option or contract to purchase, purchase any 
option or contract to sell, grant any option, right or warrant to purchase, 
lend, or otherwise transfer or dispose of, directly or indirectly, any shares 
of Common Stock or any securities convertible into or exercisable or 
exchangeable for Common Stock or (ii) enter into any swap or other 
arrangement that transfers to another, in whole or in part, any of the 
economic consequences of ownership of the Common Stock, whether any such 
transaction described in clause (i) or (ii) above is to be settled by 
delivery of Common Stock or such other securities, in cash or otherwise.  The 
foregoing sentence shall not apply to (A) the Shares to be sold hereunder, 
(B) the issuance by the Company of shares of Common Stock upon the exercise 
of options or warrants or the conversion of a security outstanding on the 
date hereof which is described in the Prospectus, or (C) the grant of options 
by the Company pursuant to the option plans described in the Registration 
Statement and Prospectus, PROVIDED, such options are not exercisable for 180 
days after the date of the Prospectus, or if such options are exercisable 
within such period, such options are subject to lockup provisions 
substantially the same as those set forth in this Section 3(c).  In addition, 
each Selling Stockholder, agrees that, without the prior written consent of 
Thomas Weisel Partners LLC, it will not, during the period ending 180 days 
after the date of the Prospectus, make any demand for, or exercise any right 
with respect to, the registration of any shares of Common Stock or any 
security convertible into or exercisable or exchangeable for Common Stock.

          (d)  TERMS OF PUBLIC OFFERING.  The Sellers are advised by you that 
the Underwriters propose to make a public offering of their respective 
portions of the Shares as soon after the Registration Statement and this 
Agreement have become effective as in your judgment is advisable.

after the first date of the public offering of the Shares as in the 
reasonable opinion of counsel for the Underwriters the Prospectus is required

(the "PROSPECTUS DELIVERY PERIOD"), any event shall occur or condition exist 
as a result of which it is necessary to amend or supplement the Prospectus in

Underwriters and to the dealers (whose names and addresses you will furnish 
to the Company) to which Shares may have been sold by you on behalf of the 
Underwriters and to any other dealers upon request, either amendments or 
supplements to the Prospectus so that the statements in the Prospectus as so 
amended or supplemented will not, in the light of the circumstances when the 
Prospectus is delivered to a purchaser, be misleading or so that the 
Prospectus, as amended or supplemented, will comply with law.

and sale under the securities or Blue Sky laws of such jurisdictions as you

          (a)  INDEMNIFICATION OF THE UNDERWRITERS.  The Sellers jointly and 
severally agree to indemnify and hold harmless each Underwriter and each 
person, if any, who controls any Underwriter within the meaning of either 
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and 
against any and all losses, claims, damages and liabilities (including, 
without limitation, any legal or other expenses reasonably incurred in 
connection with defending or investigating any such action or claim) caused 
by any untrue statement or alleged untrue statement of a material fact 
contained in the Registration Statement or any amendment thereof, any 
preliminary prospectus or the Prospectus (as amended or supplemented if the 
Company shall have furnished any amendments or supplements thereto), or 
caused by any omission or alleged omission to state therein a material fact 
required to be stated therein or necessary to make the statements therein not 


                                        16
<PAGE>

misleading, except (i) insofar as such losses, claims, damages or liabilities 
are caused by any such untrue statement or omission or alleged untrue 
statement or omission based upon information relating to any Underwriter 
furnished to the Company in writing by such Underwriter through you expressly 
for use therein and (ii) that with respect to any preliminary prospectus, the 
foregoing indemnity agreement shall not inure to the benefit of any 
Underwriter from whom the person asserting any loss, claim, damage or 
liability purchased Shares, or any person controlling such Underwriter, if 
copies of the Prospectus were timely delivered to the Underwriter pursuant to 
Section 5 and a copy of the Prospectus (as then amended or supplemented if 
the Company shall have furnished any amendments or supplements thereto) was 
not sent or given by or on behalf of such Underwriter to such person, if 
required by law so to have been delivered, at or prior to the written 
confirmation of the sale of the Shares to such person, and if the Prospectus 
(as so amended or supplemented) would have cured the defect giving rise to 
such loss, claim, damage, liability or expense.

          (b)  INDEMNIFICATION OF THE SELLING STOCKHOLDERS.  The Company 
agrees to indemnify and hold harmless each Selling Stockholder and each 
person, if any, who controls such Selling Stockholder within the meaning of 
either Section 15 of the Securities Act or Section 20 of the Exchange Act, 
from and against any and all losses, claims, damages and liabilities 
(including, without limitation, any legal or other expenses reasonably 
incurred in connection with defending or investigating any such action or 
claim) caused by any untrue statement or alleged untrue statement of a 
material fact contained in the Registration Statement or any amendment 
thereof, any preliminary prospectus or the Prospectus (as amended or 
supplemented if the Company shall have furnished any amendments or 
supplements thereto), or caused by any omission or alleged omission to state 
therein a material fact required to be stated therein or necessary to make 
the statements therein not misleading, except insofar as such losses, claims, 
damages or liabilities are caused by any such untrue statement or omission or 
alleged untrue statement or omission based upon information relating to such 
Selling Stockholder furnished to the Company in writing by such Selling 
Stockholder expressly for use therein.

          (c)  INDEMNIFICATION BY THE UNDERWRITERS.  Each Underwriter agrees, 
severally and not jointly, to indemnify and hold harmless the Company, the 
Selling Stockholders, the directors of the Company, the officers of the 
Company who sign the Registration Statement and each person, if any, who 
controls the Company or any Selling Stockholder within the meaning of either 
Section 15 of the Securities Act or Section 20 of the Exchange Act from and 
against any and all losses, claims, damages and liabilities (including, 
without limitation, any legal or other expenses reasonably incurred in 
connection with defending or investigating any such action or claim) caused 
by any untrue statement or alleged untrue statement of a material fact 
contained in the Registration Statement or any amendment thereof, any 
preliminary prospectus or the Prospectus (as amended or supplemented if the 
Company shall have furnished any amendments or supplements thereto), or 
caused by any omission or alleged omission to state therein a material fact 
required to be stated therein or necessary to make the statements therein not 
misleading, but only with reference to information relating to such 
Underwriter furnished to the Company in writing by such Underwriter 


                                        17
<PAGE>

through you expressly for use in the Registration Statement, any preliminary 
prospectus, the Prospectus or any amendments or supplements thereto.

          (d)  INDEMNIFICATION PROCEDURES.  In case any proceeding (including 
any governmental investigation) shall be instituted involving any person in 
respect of which indemnity may be sought pursuant to this Section 8, such 
person (the "INDEMNIFIED PARTY") shall promptly notify the person against 
whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing and 
the indemnifying party, upon request of the indemnified party, shall retain 
counsel reasonably satisfactory to the indemnified party to represent the 
indemnified party and any others the indemnifying party may designate in such 
proceeding and shall pay the fees and disbursements of such counsel related 
to such proceeding. In any such proceeding, any indemnified party shall have 
the right to retain its own counsel, but the fees and expenses of such 
counsel shall be at the expense of such indemnified party unless (i) the 
indemnifying party and the indemnified party shall have mutually agreed to 
the retention of such counsel or (ii) the named parties to any such 
proceeding (including any impleaded parties) include both the indemnifying 
party and the indemnified party and representation of both parties by the 
same counsel would be inappropriate due to actual or potential differing 
interests between them.  It is understood that the indemnifying party shall 
not, in respect of the legal expenses of any indemnified party in connection 
with any proceeding or related proceedings in the same jurisdiction, be 
liable for (i) the fees and expenses of more than one separate firm (in 
addition to any local counsel) for all Underwriters and all persons, if any, 
who control any Underwriter within the meaning of either Section 15 of the 
Securities Act or Section 20 of the Exchange Act, (ii) the fees and expenses 
of more than one separate firm (in addition to any local counsel) for the 
Company, its directors, its officers who sign the Registration Statement and 
each person, if any, who controls the Company within the meaning of either 
such Section and (iii) the fees and expenses of more than one separate firm 
(in addition to any local counsel) for all Selling Stockholders and all 
persons, if any, who control any Selling Stockholder within the meaning of 
either such Section, and that all such fees and expenses shall be reimbursed 
as they are incurred.  In the case of any such separate firm for the 
Underwriters and such control persons of any Underwriters, such firm shall be 
designated in writing by Thomas Weisel Partners LLC.  In the case of any such 
separate firm for the Company, and such directors, officers and control 
persons of the Company, such firm shall be designated in writing by the 
Company.  In the case of any such separate firm for the Selling Stockholders 
and such control persons of any Selling Stockholders, such firm shall be 
designated in writing by the Selling Stockholders. The indemnifying party 
shall not be liable for any settlement of any proceeding effected without its 
written consent, but if settled with such consent or if there be a final 
judgment for the plaintiff, the indemnifying party agrees to indemnify the 
indemnified party from and against any loss or liability by reason of such 
settlement or judgment.  Notwithstanding the foregoing sentence, if at any 
time an indemnified party shall have requested an indemnifying party to 
reimburse the indemnified party for fees and expenses of counsel as 
contemplated by the second and third sentences of this paragraph, the 
indemnifying party agrees that it shall be liable for any settlement of any 
proceeding effected without its written consent if (i) such settlement is 
entered into more than 30 days after receipt by such indemnifying party of 
the aforesaid request and (ii) such indemnifying party shall not have 
reimbursed the indemnified party in accordance with such request prior to the 
date of such settlement or confirmed in writing to the 


                                        18
<PAGE>

indemnified party its obligation to provide such reimbursement.  No 
indemnifying party shall, without the prior written consent of the 
indemnified party, effect any settlement of any pending or threatened 
proceeding in respect of which any indemnified party is or could have been a 
party and indemnity could have been sought hereunder by such indemnified 
party, unless such settlement includes an unconditional release of such 
indemnified party from all liability on claims that are the subject matter of 
such proceeding.

          (e)  CONTRIBUTION AGREEMENT.  To the extent the indemnification 
provided for in this Section 8 is unavailable to an indemnified party or 
insufficient in respect of any losses, claims, damages or liabilities 
referred to therein, then each indemnifying party under such paragraph, in 
lieu of indemnifying such indemnified party thereunder, shall contribute to 
the amount paid or payable by such indemnified party as a result of such 
losses, claims, damages or liabilities (i) in such proportion as is 
appropriate to reflect the relative benefits received by the indemnifying 
party or parties on the one hand and the indemnified party or parties on the 
other hand from the offering of the Shares or (ii) if the allocation provided 
by clause 8(e)(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 8(e)(i) above but also the relative fault of the 
indemnifying party or parties on the one hand and of the indemnified party or 
parties on the other hand in connection with the statements or omissions that 
resulted in such losses, claims, damages or liabilities, as well as any other 
relevant equitable considerations.  The relative benefits received by any 
Seller on the one hand and the Underwriters on the other hand in connection 
with the offering of the Shares shall be deemed to be in the same respective 
proportions as the net proceeds from the offering of the Shares (before 
deducting expenses) received by such Seller and the total underwriting 
discounts and commissions received by the Underwriters, in each case as set 
forth in the table on the cover of the Prospectus, bear to the aggregate 
price to the public of the Shares.  The relative fault of any Seller on the 
one hand and the Underwriters on the other hand 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 by such Seller or by the 
Underwriters and the parties' relative intent, knowledge, access to 
information and opportunity to correct or prevent such statement or omission. 
 The Underwriters' respective obligations to contribute pursuant to this 
Section 8 are several in proportion to the respective number of Shares they 
have purchased hereunder, and not joint. 

          (f)  CONTRIBUTION AMOUNTS.  The Sellers and the Underwriters agree 
that it would not be just or equitable if contribution pursuant to this 
Section 8 were determined by PRO RATA allocation (even if the Underwriters 
were treated as one entity for such purpose) or by any other method of 
allocation that does not take account of the equitable considerations 
referred to in Section 8(d).  The amount paid or payable by an indemnified 
party as a result of the losses, claims, damages and liabilities referred to 
in the immediately preceding paragraph shall be deemed to include, subject to 
the limitations set forth above, any legal or other expenses reasonably 
incurred by such indemnified party in connection with investigating or 
defending any such action or claim. Notwithstanding the provisions of this 
Section 8, no Underwriter shall be required to contribute any amount in 
excess of the amount by which the total price at which the Shares 
underwritten by it and 


                                        19
<PAGE>

distributed to the public were offered to the public exceeds the amount of 
any damages that such Underwriter has otherwise been required to pay by 
reason of such untrue or alleged untrue statement or omission or alleged 
omission.  No person guilty of fraudulent misrepresentation (within the 
meaning of Section 11(f) of the Securities Act) shall be entitled to 
contribution from any person who was not guilty of such fraudulent 
misrepresentation.  The remedies provided for in this Section 8 are not 
exclusive and shall not limit any rights or remedies which may otherwise be 
available to any indemnified party at law or in equity. 

          (g)  SURVIVAL OF PROVISIONS.  The indemnity and contribution 
provisions contained in this Section 8 and the representations, warranties 
and other statements of the Company and the Selling Stockholders contained in 
this Agreement shall remain operative and in full force and effect regardless 
of (i) any termination of this Agreement, (ii) any investigation made by or 
on behalf of any Underwriter or any person controlling any Underwriter, any 
Selling Stockholder or any person controlling any Selling Stockholder, or the 
Company, its officers or directors or any person controlling the Company and 
(iii) acceptance of and payment for any of the Shares.

          (h)  CLAIMS FOR INDEMNIFICATION.  The Company and each of the 
Underwriters agree with each of the Selling Stockholders that any claim of 
such Underwriter against such Selling Stockholder for indemnification 
pursuant to Section 8(a) hereof shall first be sought by such Underwriter to 
be satisfied in full by the Company and, subject to the limitation on the 
aggregate liability of each Selling Stockholder set forth in Section 8(i) 
hereof, shall be satisfied by the Selling Stockholders only to the extent 
that such claim has not been satisfied in full by the Company within the 
sixty (60) day period following the date requested for payment in accordance 
with the terms of this Agreement.

          (i)  LIMITATION OF SELLING STOCKHOLDER LIABILITY.  The aggregate 
liability of each Selling Stockholder for breaches of representations and 
warranties under Section 2 hereof and under the indemnity and contribution 
provisions of this Section 8 shall be limited to an amount equal to the 
aggregate initial public offering price of the Shares sold by such Selling 
Stockholder, less the underwriting discount, as set forth on the front cover 
page of the Prospectus.  The Company and the Selling Stockholders may agree, 
as among themselves and without limiting the rights of the Underwriters under 
this Agreement, as to the respective amounts of such liability for which they 
each shall be responsible.  The Company and the Selling Stockholders agree 
that that agreements by the Company and the Selling Stockholders hereunder 
shall not reduce the obligations of the Company to indemnify the Selling 
Stockholders pursuant to the Amended and Restated Investors' Rights Agreement 
dated November 19, 1997.

     9.   EFFECTIVENESS.  This Agreement shall become effective upon the 
execution and delivery hereof by the parties hereto.

     10.  TERMINATION.  This Agreement shall be subject to termination by 
notice given by you to the Company, if (a) after the execution and delivery 
of this Agreement and prior to the Closing Date (i) trading generally shall 
have been suspended or materially limited on or by, as the case may 


                                        20
<PAGE>

be, any of the New York Stock Exchange, the American Stock Exchange, the 
National Association of Securities Dealers, Inc., the Chicago Board of 
Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of 
Trade, (ii) trading of any securities of the Company shall have been 
suspended on any exchange or in any over-the-counter market, (iii) a general 
moratorium on commercial banking activities in New York, Delaware or 
California shall have been declared by either federal or New York, Delaware 
or California state authorities or (iv) there shall have occurred any 
outbreak or escalation of hostilities or any change in financial markets or 
any calamity or crisis that, in your judgment, is material and adverse, or 
(v) in the judgment of the Representatives, there shall have occurred any 
material adverse change, or any development that could reasonably be expected 
to result in a material adverse change, in the condition, financial or 
otherwise, or in the earnings, business, operations or prospects, whether or 
not arising from transactions in the ordinary course of business, of the 
Company and Subsidiary, taken as a whole, and (b) in the case of any of the 
events specified in clauses 10(a)(i) through 10(a)(v), such event, 
individually or together with any other such event, makes it, in your 
judgment, impracticable to market the Shares on the terms and in the manner 
contemplated in the Prospectus.

     11.  DEFAULTING UNDERWRITERS.  If, on the Closing Date or the Option
Closing Date, as the case may be, any one or more of the Underwriters shall fail
or refuse to purchase Shares that it has or they have agreed to purchase
hereunder on such date, and the aggregate number of Shares which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the aggregate number of the Shares to be purchased on such
date, the other Underwriters shall be obligated severally in the proportions
that the number of Firm Shares set forth opposite their respective names in
SCHEDULE A bears to the aggregate number of Firm Shares set forth opposite the
names of all such non-defaulting Underwriters, or in such other proportions as
you may specify, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date; PROVIDED
that in no event shall the number of Shares that any Underwriter has agreed to
purchase pursuant to this Agreement be increased pursuant to this Section 11 by
an amount in excess of one-ninth of such number of Shares without the written
consent of such Underwriter.  If, on the Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Firm Shares and the aggregate
number of Firm Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Firm Shares to be purchased, and
arrangements satisfactory to you, the Company and the Selling Stockholders for
the purchase of such Firm Shares are not made within 36 hours after such
default, this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter, the Company or the Selling Stockholders.  In any
such case either you or the relevant Sellers shall have the right to postpone
the Closing Date, but in no event for longer than seven (7) days, in order that
the required changes, if any, in the Registration Statement and in the
Prospectus or in any other documents or arrangements may be effected.  If, on
the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to
purchase Additional Shares and the aggregate number of Additional Shares with
respect to which such default occurs is more than one-tenth of the aggregate
number of Additional Shares to be purchased, the non-defaulting Underwriters
shall have the option to (i) terminate their obligation hereunder to purchase
Additional Shares or (ii) purchase not less than the number of Additional Shares
that such non-defaulting Underwriters would have been obligated to purchase in
the absence 


                                        21
<PAGE>

of such default.  Any action taken under this paragraph shall not relieve any 
defaulting Underwriter from liability in respect of any default of such 
Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of 
them, because of any failure or refusal on the part of any Seller to comply 
with the Sellers' obligations under this Agreement (including without 
limitation a failure of any Selling Stockholder to sell and deliver the 
Shares covered in Section 18), or if for any reason any Seller shall be 
unable to perform its obligations under this Agreement, the Sellers, 
severally, will reimburse the Underwriters or such Underwriters as have so 
terminated this Agreement with respect to themselves for all out-of-pocket 
expenses (including the fees and disbursements of their counsel) reasonably 
incurred by such Underwriters in connection with this Agreement or the 
offering contemplated hereunder.

     12.  COUNTERPARTS.  This Agreement may be signed in counterparts, each 
of which shall be an original, with the same effect as if the signatures 
thereto and hereto were upon the same instrument.

     13.  HEADINGS; TABLE OF CONTENTS.  The headings of the sections of this 
Agreement and the table of contents have been inserted for convenience of 
reference only and shall not be deemed a part of this Agreement.

binding upon the parties hereto, including any substitute Underwriters 
pursuant to Section 11 hereof, and to the benefit of the officers and 
directors and controlling persons referred to in Section 8, and in each case 
their respective successors, and no other person will have any right or 
obligation hereunder as a third party beneficiary or otherwise.  The term 
"successors" shall not include any purchaser of the Shares as such from any 
of the Underwriters merely by reason of such purchase.

     16.  PARTIAL UNENFORCEABILITY.  The invalidity or unenforceability of 
any Section, paragraph or provision of this Agreement shall not affect the 
validity or enforceability of any other Section, paragraph or provision 
hereof.  If any Section, paragraph or provision of this Agreement is for any 
reason determined to be invalid or unenforceable, there shall be deemed to be 
made such minor changes (and only such minor changes) as are necessary to 
make it valid and enforceable.

ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

     18.  FAILURE OF THE SELLING STOCKHOLDERS TO SELL AND DELIVER SHARES.  If 
one or more of the Selling Stockholders shall fail to sell and deliver to the 
Underwriters the Shares to be sold and delivered by such Selling Stockholders 
at the Closing Date pursuant to this Agreement, then the Underwriters may at 
their option, by written notice from the Representatives to the Company and 
the Selling Stockholders, either (i) except as provided in Section 8, 
terminate this Agreement without any liability on the part of any Underwriter 
or, except as provided in Sections 7 and 8 hereof, the Company or the Selling 
Stockholders, or (ii) purchase the shares which the Company and other Selling 
Stockholders have agreed to sell and deliver in accordance with the terms 
hereof.  If one or more of the Selling Stockholders shall fail to sell and 
deliver to the Underwriters the Shares to be sold and delivered by such 
Selling Stockholders pursuant to this Agreement at the Closing Date or the 
Option Closing Date, then the Underwriters shall have the right, by written 
notice from the Representatives to the Company and the Selling Stockholders, 
to postpone the Closing Date or the Option Closing Date, as the case may be, 
but in no event for longer than seven (7) days in order that the required 
changes, if any, to the Registration Statement and the Prospectus or any 
other documents or arrangements may be effected. 

     19.  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement 
of the parties to this Agreement and supersedes all prior written or oral and 
all contemporaneous oral agreements, understandings and negotiations with

counsel during negotiations regarding the provisions hereof, including,

Section 8, and is fully informed regarding said provisions.  Each of the 
parties hereto further acknowledges that the provisions of Section 8 hereto 
fairly allocate the risks in light of the ability of the parties to

adequate disclosure has been made in the Registration Statement, any 
preliminary prospectus and the Prospectus (and any amendments and supplements 
thereto), as required by the Securities Act and the Exchange Act.

                                   EXHIBIT A

                    FORM OF LEGAL OPINION OF COMPANY COUNSEL


      THE FINAL OPINION IN DRAFT FORM SHOULD BE ATTACHED AS EXHIBIT A AT THE 
TIME THIS AGREEMENT IS EXECUTED.

     (i)   The Company is duly incorporated and is validly existing and in 
good standing under the laws of the State of Delaware; the Company has the 
corporate power and authority to own, lease and operate its properties and to 
conduct its business as described in the Registration Statement and the 
Prospectus (and any amendment or supplement thereto); the Company is duly 
qualified to transact business and is in good standing in each jurisdiction 
or place where the nature of its properties or the conduct of its business 
requires such qualification, except where the failure to so qualify does not 
have a material adverse effect on the Company and Subsidiary, taken as a 
whole ("MATERIAL ADVERSE EFFECT").

    (ii)   The Company has one subsidiary, Rubio's Restaurants of Nevada, 
Inc., a Nevada corporation (the "SUBSIDIARY"); the Subsidiary has been duly 
incorporated and is validly existing and in good standing under the laws of 
the jurisdiction of incorporation; the Subsidiary has the corporate power and 
authority to own, lease and operate its properties and to conduct the 
business in which it is engaged; the Subsidiary is duly qualified to transact 
business and is in good standing in each jurisdiction or place where the 
nature of its properties or the conduct of its business requires such 
qualification, except where the failure to so qualify does not have a 
Material Adverse Effect; all of the issued shares of capital stock of 
Subsidiary have been duly and validly authorized and issued, are fully paid 
and nonassessable and are owned directly by the Company, free and clear of 
all liens, encumbrances, equities and claims.

    (iii)   The statements set forth under the caption "Description of Capital 
Stock" in the Prospectus, insofar as such statements purport to summarize 
certain provisions of the capital stock of the Company, provide a fair 
summary of such provisions; to our knowledge, except as described in the 
Prospectus, there are no outstanding securities of the Company or the 
Subsidiary convertible or exchangeable into, or evidencing the right to 
purchase or subscribe for, any shares of capital stock of the Company or the 
Subsidiary and there are no outstanding or authorized options, warrants or 
rights of a similar character obligating the Company or the Subsidiary to 
issue any shares of their respective capital stock or any securities 
convertible or exchangeable into, or evidencing the right to purchase or 
subscribe for, any shares of such stock.

    (iv)   All the shares of capital stock of the Company (including the 
Shares to be sold by the Selling Stockholders) outstanding prior to the 
issuance of the Shares have been duly authorized and validly issued, and are 
fully paid and nonassessable.

<PAGE>

     (v)   The Shares to be sold by the Company have been duly authorized 
and, when issued and delivered to the Underwriters against payment therefor 
in accordance with the terms of the Underwriting Agreement, will be validly 
issued, fully paid and nonassessable and free of (A) any preemptive rights 
arising under the Restated Certificate or the Delaware General Corporation 
Law or (B) to our knowledge, similar rights that entitle or will entitle any 
person to acquire any shares of capital stock of the Company upon the 
issuance and sale of the Shares by the Company.

    (vi)   The Underwriting Agreement has been duly authorized, executed and 
delivered by the Company.

   (vii)   Neither the offer, sale or delivery of the Shares, the execution, 
delivery or performance by the Company of the Underwriting Agreement, 
compliance by the Company with the provisions of the Underwriting Agreement 
nor consummation by the Company of the transactions contemplated by the 
Underwriting Agreement (A) violates the Restated Certificate or the Bylaws, 
or the organizational documents, of the Company, or (B) constitutes a breach 
of, or a default under, any agreement, indenture, lease or other instrument 
to which the Company is a party or by which the Company or any of its 
properties is bound that is an exhibit to the Registration Statement, which 
breach or default could reasonably be expected to have a Material Adverse 
Effect or (C) will result in any violation of any existing law or regulation 
(other than applicable state securities or Blue Sky laws, as to which we 
express no opinion), or any ruling, judgment, injunction, order or decree 
known to us and applicable to the Company or any of its properties.

  (viii)   No consent, approval, authorization or other order of, or 
registration or filing with, any court, regulatory body, administrative 
agency or other governmental body, agency, or official is required on the 
part of the Company (except (A) as have been obtained under the Securities 
Act and the Exchange Act or (B) such as may be required under state 
securities or Blue Sky laws governing the purchase and distribution of the 
Shares, as to which we express no opinion) for the valid issuance and sale of 
the Shares to the Underwriters as contemplated by the Underwriting Agreement.

    (ix)   The statements set forth in (A) under the captions "Risk Factors - 
Risks Related to this Offering - The large number of shares eligible for 
public sale after this offering could cause our stock price to decline," 
"Management - Benefit Plans," "Shares Eligible for Future Sale," "Description 
of Capital Stock" and "Underwriting" in the Prospectus, and (B) in the 
Registration Statement in Items 14 and 15, insofar as such statements 
constitute a summary of the legal matters, documents or proceedings referred 
to therein, provide a fair summary of such legal matters, documents and 
proceedings in all material respects.

      (x)  To our knowledge, (A) there are no legal or governmental 
proceedings pending or threatened against the Company or the Subsidiary, or 
to which the Company, the Subsidiary or any of their respective properties 
are subject, which are required to be described in the Registration Statement 
or Prospectus (or any amendment or supplement thereto) that are not so 
described and (B) there are no agreements, contracts, indentures, leases or 
other instruments that are required to be described in the Registration 
Statement or the Prospectus (or any amendment or supplement thereto)


                                        2
<PAGE>


or to be filed as an exhibit to the Registration Statement that are not so 
described or filed, as the case may be.

     (xi)  The Company is not an "investment company" or a person 
"controlled" by an "investment company" within the meaning of the Investment 
Company Act of 1940, as amended.

    (xii)  The Registration Statement and the Prospectus and any supplements 
or amendments thereto (except for the consolidated financial statements and 
the notes thereto and the schedules and other financial and statistical data 
included therein, as to which we do not express any opinion) comply as to 
form in all material respects with the requirements of the Securities Act and 
the applicable rules and regulations of the Commission thereunder.

     Such counsel (A) has no reason to believe that (except for financial 
statements and schedules and other financial and statistical data as to which 
such counsel need not express any belief) the Registration Statement and the 
prospectus include therein at the time the Registration Statement became 
effective contained any untrue statement of a material fact or omitted to 
state a material fact required to be stated therein or necessary to make the 
statements therein not misleading and (B) has no reason to believe that 
(except for financial statements and schedules and other financial and 
statistical data as to which such counsel need not express any belief) the 
Prospectus contains any untrue statement of a material fact or omits to state 
a material fact necessary in order to make the statements therein, in the 
light of the circumstances under which they were made, not misleading

     With respect to paragraph (xii) of EXHIBIT A, such counsel may state 
that their opinion and belief are based upon their participation in the 
preparation of the Registration Statement and Prospectus and any amendments 
or supplements thereto and review and discussion of the contents thereof, but 
are without independent check or verification, except as specified.

                                   EXHIBIT B

                LEGAL OPINION OF SELLING STOCKHOLDERS' COUNSEL

    (i)  The Underwriting Agreement has been duly authorized, executed and 
delivered by or on behalf of each of the Selling Stockholders.

    (ii) The execution and delivery by each Selling Stockholder of, and the 
performance by such Selling Stockholder of its obligations under, the 
Underwriting Agreement and the Custody Agreement and Powers of Attorney of 
such Selling Stockholder will not contravene any provision of applicable law, 
or, to our  knowledge, any agreement or other instrument binding upon such 
Selling Stockholder or, any judgment, order or decree of any governmental 
body, agency or court having jurisdiction over such Selling Stockholder, and 
no consent, approval, authorization or order of, or qualification with, any 
governmental body or agency is required for the performance by such Selling 
Stockholder of its obligations under the Underwriting Agreement, the Custody 
Agreement or Power of Attorney of such Selling Stockholder, except such as 
may be required by federal securities laws, and the securities or Blue Sky 
laws of the various states in connection with offer and sale of the Shares.

    (iii) Each of the Selling Stockholders has valid title to the Shares 
to be sold by such Selling Stockholder and the legal right and power, and all 
authorization and approval required by law, to enter into the Underwriting 
Agreement and the Custody Agreement and Power of Attorney of such Selling 
Stockholder and to sell, transfer and deliver the Shares to be sold by such 
Selling Stockholder.

    (iv) The Custody Agreement and the Power of Attorney of each Selling 
Stockholder have been duly authorized, executed and delivered by such Selling 
Stockholder and are valid and binding agreements of such Selling Stockholder.

    (v)  Assuming the Underwriters, severally, acquire the Shares to be sold 
by each Selling Stockholder pursuant to the Underwriting Agreement in good 
faith and without actual notice of any adverse claims, upon the delivery to 
the Underwriters of the certificates representing such Shares in accordance 
with the instructions from the Representatives and payment for such Shares, 
delivery of the Shares to be sold by each Selling Stockholder pursuant to the 
Underwriting Agreement will pass title to such Shares free and clear of any 
"Adverse Claims" as defined in Section 8302(2) of the California Commercial 
Code.

    Such counsel may rely with respect to factual matters and to the extent 
such counsel deems appropriate, upon the representations of each Selling 
Stockholder contained in the Underwriting Agreement and in the Custody 
Agreement and Power of Attorney of such Selling Stockholder and in other 
documents and instruments; provided that copies of such Custody Agreements 
and Powers of 


                                        
<PAGE>

Attorney and of any such other documents and instruments shall 
be delivered to counsel to the Underwriters and shall be in form and 
substance satisfactory to counsel to the Underwriters.

 Re:  LOCK-UP AGREEMENT (THE "AGREEMENT")

Ladies and Gentlemen:

      The undersigned is an owner of record or beneficially of certain
shares of common stock, par value $0.001 per share (the "COMMON STOCK"), of
Rubio's Restaurants, Inc., a Delaware corporation (the "COMPANY"), or
securities convertible into or exchangeable or exercisable for Common
Stock.  The undersigned understands that you, as representatives (the
"REPRESENTATIVES"), propose to enter into an Underwriting Agreement on
behalf of the several Underwriters named in SCHEDULE A to such agreement
(collectively, the "UNDERWRITERS"), with the Company providing for a public
offering of the Common Stock of the Company pursuant to a Registration
Statement on Form S-1 to be filed with the Securities and Exchange
Commission (the "PUBLIC OFFERING").  The undersigned recognizes that the
Public Offering will be of benefit to the undersigned and will benefit the
Company by, among other things, raising additional capital for its
operations.  The undersigned acknowledges that you and the other
Underwriters are relying on the representations and agreements of the
undersigned contained in this letter in carrying out the Public Offering
and in entering into underwriting arrangements with the Company with
respect to the Public Offering.  

      To induce the Underwriters that may participate in the Public
Offering to continue their efforts in connection with the Public Offering,
the undersigned hereby agrees that, without the prior written consent of
Thomas Weisel Partners (which consent may be withheld in its sole
discretion), it will not, during the period commencing on the date hereof
and ending 180 days after the date of the final prospectus relating to the
Public Offering (the "PROSPECTUS"), (1) offer, pledge, sell, contract to
sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of
Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock, or (2) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of the Common Stock, 

<PAGE>

whether any such transaction described in clause (1) or (2) above is to be 
settled by delivery of Common Stock or such other securities, in cash or 
otherwise. In addition, the undersigned agrees that, without the prior 
written consent of Thomas Weisel Partners (which consent may be withheld in 
its sole discretion), it will not, during the period commencing on the date 
hereof and ending 180 days after the date of the Prospectus, make any demand 
for or exercise any right with respect to, the registration of any shares of 
Common Stock or any security convertible into or exercisable or exchangeable 
for Common Stock.  With respect to the Public Offering, the undersigned 
waives any registration rights relating to registration under the Securities 
Act of 1933, as amended, of any Common Stock owned either of record or 
beneficially by the undersigned, including any rights to receive notice of 
the Public Offering.

      The foregoing restrictions are expressly agreed to preclude the 
undersigned from engaging in any hedging or other transaction which is 
designed to or reasonably expected to lead to or result in a sale or 
disposition of the Common Stock even if such Common Stock would be disposed 
of by someone other than the undersigned.  Such prohibited hedging or other 
transactions would include without limitation any short sale or any purchase, 
sale or grant of any right (including without limitation any put option or 
put equivalent position or call option or call equivalent position) with 
respect to any of the Common Stock or with respect to any security that 
includes, relates to, or derives any significant part of its value from such 
Common Stock.

      Notwithstanding the foregoing, the undersigned may transfer shares of 
Common Stock (i) as a bona fide gift or gifts, PROVIDED that the donee or 
donees thereof agree to be bound by the restrictions set forth herein, (ii) 
to any trust for the direct or indirect benefit of the undersigned or the 
immediate family of the undersigned, PROVIDED that the trustee of the trust 
agrees to be bound by the restrictions set forth herein, and PROVIDED FURTHER 
that any such transfer shall not involve a disposition for value or (iii) to 
the Underwriters pursuant to the Underwriting Agreement.  For purposes of 
this Agreement, "immediate family" shall mean any relationship by blood, 
marriage or adoption, not more remote than first cousin.  In addition, 
notwithstanding the foregoing, if the undersigned is a corporation, the 
corporation may transfer the capital stock of the Company to any wholly-owned 
subsidiary of such corporation; PROVIDED, HOWEVER, that in any such case, it 
shall be a condition to the transfer that the transferee execute an agreement 
stating that the transferee is receiving and holding such capital stock 
subject to the provisions of this Agreement and there shall be no further 
transfer of such capital stock except in accordance with this Agreement, and 
PROVIDED FURTHER that any such transfer shall not involve a disposition for 
value.

      The undersigned understands that whether or not the Public Offering 
actually occurs depends on a number of factors, including stock market 
conditions.  The Public Offering will only be made pursuant to an 
Underwriting Agreement, the terms of which are subject to negotiation among 
the Company and the Underwriters. 

      The undersigned agrees and consents to the entry of stop transfer 
instructions with the Company's transfer agent and registrar against the 
transfer of shares of Common Stock or securities 


                                        2
<PAGE>

convertible into or exchangeable or exercisable for Common Stock held by the 
undersigned except in compliance with the foregoing restrictions.

      This agreement is irrevocable and will be binding on the
undersigned and the respective successors, heirs, personal representatives,
and assigns of the undersigned.

                                        Very truly yours,

          Re:  Rubio's Restaurants, Inc. Registration Statement on Form S-1 
               for 3,622,500 Shares of Common Stock

Ladies and Gentlemen:

          We have acted as counsel to Rubio's Restaurants, Inc., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of up to 3,622,500 shares of the Company's Common Stock (the
"Shares"), including 472,000 Shares which the underwriters have the option to
purchase to cover overallotments, if any, pursuant to the Company's Registration
Statement on Form S-1 (the "Registration Statement") filed with the Securities
and Exchange Commission under the Securities Act of 1933, as amended (the
"Act").

          This opinion is being furnished in accordance with the requirements of
Item 16(a) of Form S-1 and Item 601(b)(5)(i) of Regulation S-K.

          We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares.  Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and the related prospectus (as amended and supplemented through the
date of issuance) will be legally issued, fully paid and nonassessable.

          We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement. 
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
Item 509 of Regulation S-K.

per share, subject to adjustment as provided herein.

     3.   METHOD OF EXERCISE.

          3.1  EXERCISE OF WARRANT; PARTIAL EXERCISE.  This Warrant may be
exercised in full or in part by FSC Corp. by surrender of this Warrant, together
with the form of subscription attached hereto as EXHIBIT A duly executed by FSC
Corp., to the Company at its principal office, accompanied by payment, in cash
or by certified or official bank check payable to the order of the Company, of
the Exercise Price of the Warrant Shares to be purchased hereunder.  For any
partial exercise hereof, FSC Corp. shall designate in a subscription in the form
of EXHIBIT A attached hereto delivered to the Company the number of Warrant
Shares that it wishes to purchase.  On any such partial exercise, the Company at
its expense shall forthwith issue and deliver to FSC Corp. a new warrant of like
tenor, in the name of FSC Corp., which shall be exercisable for such number of
Warrant Shares represented by this Warrant which have not been purchased upon
such exercise.

          3.2  NET ISSUANCE.  

               3.2.1     RIGHT TO CONVERT.  In addition to and without limiting
the rights of FSC Corp. under the terms of this Warrant, FSC Corp. shall have
the right to convert this Warrant or any portion thereof (the "Conversion
Right") into shares of Series D Preferred Stock as provided in this Section 3.2
at any time or from time to time prior to the Expiration Date.

Upon exercise of the Conversion Right with respect to a particular number of
shares subject to the Warrant (the "Converted Warrant Shares"), the Company
shall deliver to FSC Corp. (without payment by FSC Corp. of any exercise price
or any cash or other consideration) that number of shares of fully paid and
nonassessable Series D Preferred Stock computed using the following formula:

                    X = Y (A - B)
                          -------
                             A

     Where:    X   =     the number of shares of Series D Preferred Stock to
                         be delivered to FSC Corp.

                Y   =     the number of Converted Warrant Shares

                                     3


<PAGE>

                A   =     the per share fair market value of the Series D
                          Preferred Stock on the Conversion Date (as defined
                          below)

                B   =     the Exercise Price of the Warrant (as adjusted to
                          the Conversion Date)

The Conversion Right may only be exercised with respect to a whole number of
shares subject to the Warrant.  No fractional shares shall be issuable upon
exercise of the Conversion Right, and if the number of shares to be issued
determined in accordance with the foregoing formula is other than a whole
number, the Company shall pay to FSC Corp. an amount in cash equal to the fair
market value of the resulting fractional share on the Conversion Date (as
defined below).  Shares issued pursuant to the Conversion Right shall be treated
as if they were issued upon the exercise of the Warrant.

               3.2.2     METHOD OF EXERCISE.  The Conversion Right may be
exercised by FSC Corp. by the surrender of the Warrant at the principal office
of the Company together with a written statement specifying that FSC Corp.
thereby intends to exercise the Conversion Right and indicating the total number
of shares under the Warrant that FSC Corp. is exercising through the Conversion
Right.  Such conversion shall be effective upon receipt by the Company of the
Warrant together with the aforesaid written statement, or on such later date as
is specified therein (the "Conversion Date").  Certificates for the shares
issuable upon exercise of the Conversion Right and, if applicable, a new warrant
evidencing the balance of the shares remaining subject to the Warrant, shall be
issued as of the Conversion Date and shall be delivered to FSC Corp. promptly
following the Conversion Date.

               3.2.3     DETERMINATION OF FAIR MARKET VALUE.  For purposes of
this Section 3.2, fair market value of a share of Series D Preferred Stock on
the Conversion Date shall mean:

          (i)   If the Conversion Right is exercised in connection with the
          Company's initial public offering pursuant to a registration statement
          (a "Public Offering"), and if the Company's Registration Statement
          relating to such Public Offering has been declared effective by the
          Securities and Exchange Commission, the initial "Price to Public"
          specified in the final prospectus with respect to such offering times
          the number of shares of Common Stock into which each Converted Warrant
          Share is then convertible.
          
          (ii)  If the Conversion Right is exercised in connection with an
          Acquisition, the effective per share consideration to be received in
          an Acquisition by holders of the Common Stock, which price shall be as
          specified in the agreement entered into with respect to such
          Acquisition and determined assuming receipt of the aggregate exercise
          price of all outstanding warrants to purchase equity securities of the
          Company (the "Outstanding Warrants"), or if no such price is set forth
          in the agreement concerning the Acquisition, than as determined in
          good faith by the Company's Board of Directors upon a review of
          relevant factors, including the aggregate exercise price of all
          Outstanding Warrants.

                                     4


<PAGE>

          (iii) If the Conversion Right is not exercised in connection with an
          Acquisition or in connection with and contingent upon a Public
          Offering, then as follows:

                (A)  If such type of security is traded on a securities
          exchange, the fair market value shall be deemed to be the average of
          the closing prices of such type of security on such exchange over the
          30-day period ending five business days prior to the Conversion Date;
     
                (B) If such type of security is traded over-the-counter,
          the fair market value shall be deemed to be the average of the closing
          bid prices of such type of security over the 30-day period ending five
          business days prior to the Conversion Date; and
     
                (C) If there is no public market for such type of security,
          then fair market value shall be determined by mutual agreement of FSC
          Corp. and the Company, and if FSC Corp. and the Company are unable to
          so agree, by an investment banker of national reputation selected by
          the Company and reasonably acceptable to FSC Corp..  All fees and
          expenses for such investment banker shall be paid for by FSC Corp..

          3.3   WHEN EXERCISE EFFECTIVE.  The exercise of this Warrant shall be
deemed to have been effected immediately prior to the close of business on the
business day on which this Warrant and any other items necessary for the
effective exercise of this Warrant are surrendered to the Company as provided in
this Section 3, and at such time the person in whose name any certificate for
shares of Series D Preferred Stock are issuable upon such exercise, as provided
in Section 3.3, shall be deemed to be the record holder of such Series D
Preferred Stock for all purposes.

          3.4   DELIVERY ON EXERCISE.  As soon as practicable after the
exercise of this Warrant in full or in part, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to FSC Corp., or as FSC Corp. may direct, a
certificate or certificates for the number of fully paid and nonassessable full
shares of Series D Preferred Stock to which FSC Corp. shall be entitled on such
exercise.

          4.    ADJUSTMENTS TO SERIES D PREFERRED STOCK AND EXERCISE PRICE. 
The number of shares of Series D Preferred Stock (or any shares of stock or
other securities which may be) issuable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time upon the
happening of certain events, as follows:  

          4.1   SPLITS AND SUBDIVISIONS.  In the event the Company should at
any time or from time to time fix a record date for the effectuation of a split
or subdivision of the outstanding shares of Series D Preferred Stock or the
determination of the holders of Series D Preferred Stock entitled to receive a
dividend or other distribution payable in additional shares of Series D
Preferred Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Series D
Preferred Stock ("SERIES D PREFERRED STOCK EQUIVALENTS") without payment of any
consideration by such holder for the additional shares of Series D Preferred
Stock or Series D Preferred Stock Equivalents (including the 

                                     5


<PAGE>

additional shares of Series D Preferred Stock issuable upon conversion or 
exercise thereof), then, as of such record date (or the date of such split, 
subdivision, dividend or other distribution if no record date is fixed), the 
Exercise Price shall be appropriately decreased and the number of shares of 
Series D Preferred Stock issuable upon exercise of this Warrant shall be 
appropriately increased in proportion to such increase in outstanding shares 
of Series D Preferred Stock.

          4.2   COMBINATION OF SHARES.  If the number of shares of Series D
Preferred Stock outstanding at any time after the date hereof is decreased by a
combination of the outstanding shares of Series D Preferred Stock, the Exercise
Price shall be appropriately increased and the number of shares of Series D
Preferred Stock issuable upon exercise of this Warrant shall be appropriately
decreased in proportion to such decrease in outstanding shares of Series D
Preferred Stock.

          4.3   ADJUSTMENTS FOR OTHER DISTRIBUTIONS.  In the event the Company
shall declare a distribution payable to the holders of Series D Preferred Stock
in securities of other persons, evidences of indebtedness issued by the Company
or other persons, assets (excluding cash dividends) or options or rights not
referred to in Section 4.1, then, in each such case for the purpose of this
Section 4.3, upon exercise of this Warrant FSC Corp. shall be entitled to a
proportionate share of any such distribution as though FSC Corp. was the holder
of the number of shares of Series D Preferred Stock of the Company issuable upon
exercise of this Warrant as of the record date fixed for the determination of
the holders of Series D Preferred Stock entitled to receive such distribution.

          4.4   RECLASSIFICATION OR REORGANIZATION.  If the Series D Preferred
Stock (or any shares of stock or other securities which may be) issuable upon
exercise of this Warrant shall be changed into the same or different number of
shares of any class or classes of stock, whether by capital reorganization,
reclassification or otherwise (other than a subdivision or combination of shares
or stock dividend provided for in Sections 4.1, 4.2 or 4.3 above, or an
acquisition of all or substantially all of the Company's outstanding stock or
assets by an unrelated entity, by merger or otherwise, prior to which this
Warrant shall cease to be exercisable as provided above), then and in each such
event FSC Corp. shall be entitled to receive upon the exercise of this Warrant
the kind and amount of shares of stock and other securities and property
receivable upon such reorganization, reclassification or other change, to which
a holder of the number of shares of Series D Preferred Stock (or any shares of
stock or other securities which may be) issuable upon exercise of this Warrant
would have received if this Warrant had been exercised immediately prior to such
reorganization, reclassification or other change.

          4.5   NOTICE OF ADJUSTMENTS AND RECORD DATES.  The Company shall
promptly notify FSC Corp. in writing of each adjustment or readjustment of the
Exercise Price and the number of shares of Series D Preferred Stock (or any
shares of stock or other securities which may be) issuable upon exercise of this
Warrant.  Such notice shall state the adjustment or readjustment and show in
reasonable detail the facts on which the adjustment or readjustment is based. 
In the event of any taking by the Company of a record of (a) the holders of
Series D Preferred Stock for the purpose of determining the holders thereof who
are entitled to receive any dividend or other distribution, or (b) the holders
of the Company's outstanding capital stock for the purpose of approving any
acquisition of all or substantially all of the Company's outstanding stock or
assets by an unrelated entity, by merger or otherwise, the Company shall 

                                     6


<PAGE>


notify FSC Corp. in writing of such record date at least twenty (20) days 
prior to such record date.

          4.6   NO IMPAIRMENT.  The Company will not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Warrant.

5.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby 
represents and warrants that:

          5.1  STOCK TO BE RESERVED.  The Company will at all times reserve and
keep available out of its authorized Series D Preferred Stock and Common Stock,
solely for the purpose of issuance upon the exercise of this Warrant as herein
provided, such number of shares of Series D Preferred Stock as shall then be
issuable upon the exercise of this Warrant and such number of shares of Common
Stock as shall be issuable upon conversion of such Series D Preferred Stock. 
The Company shall from time to time in accordance with applicable law increase
the authorized amount of its Series D Preferred Stock and/or Common Stock if at
any time the number of shares of Series D Preferred Stock and/or Common Stock
remaining unissued and available for issuance shall not be sufficient to permit
exercise of this Warrant and the conversion of such shares of Series D Preferred
Stock to Common Stock.  The Company covenants that, upon issuance in accordance
with the terms of this Warrant, all shares of Series D Preferred Stock which
shall be so issued and any Common Stock issued upon the conversion of such
Series D Preferred Stock, shall be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and, without limiting the generality of the foregoing, the
Company will take all such action as may be necessary to assure that all such
shares of Series D Preferred Stock and Common Stock may be so issued without
violation of any applicable law or regulation, or of any requirements of any
national securities exchange upon which shares of capital stock of the Company
may be listed.

          5.2  ISSUE TAX.  The issuance of certificates for shares of Series D
Preferred Stock upon exercise of this Warrant shall be made without charge to
FSC Corp. for any issue tax in respect thereof provided that the Company shall
not be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any certificate in a name other than
that of FSC Corp. of this Warrant.

          5.3  CLOSING OF BOOKS.  The Company will at no time close its transfer
books against the transfer of the shares of Series D Preferred Stock issued or
issuable upon the exercise of this Warrant in any manner which interferes with
the timely exercise of this Warrant.

                                     7

6.   REPRESENTATIONS AND WARRANTIES OF FSC CORP. FSC Corp. hereby represents 
and warrants that:

6.1  AUTHORIZATION. FSC Corp. represents that it has full power and authority 
to enter into this Warrant and that this Warrant constitutes a valid and 
legally binding obligation of FSC Corp..

6.2  PURCHASE ENTIRELY FOR OWN ACCOUNT.  This Warrant is issued and sold to 
FSC Corp. in reliance upon FSC Corp.'s representation to the Company, which 
by FSC Corp.'s execution of this Warrant FSC Corp. hereby confirms, that this 
Warrant, the Series D Preferred Stock issuable upon exercise hereof and the 
Common Stock issuable upon conversion of such Series D Preferred Stock 
(collectively, the "Securities") will be acquired for investment for FSC 
Corp.'s own account, not as a nominee or agent, and not with a view to the 
resale or distribution of any part thereof, and that FSC Corp. has no present 
intention of selling, granting any participation in, or otherwise 
distributing the same.  By executing this Warrant, FSC Corp. further 
represents that FSC Corp. does not have any contract, undertaking, agreement 
or arrangement with any person to sell, transfer or grant participations to 
such person or to any third person, with respect to any of the Securities.

6.3  RELIANCE UPON FSC CORP.'S REPRESENTATIONS. FSC Corp. understands that 
this Warrant is not, and any Series D Preferred Stock acquired upon the 
exercise hereof and any Common Stock acquired upon the conversion of any such 
Series D Preferred Stock at time of issuance may not be, registered under the 
Securities Act on the ground that the sale provided for in this Warrant and 
the issuance of the Series D Preferred Stock hereunder is exempt from 
registration under the Securities Act pursuant to Section 4(2) thereof or 
Regulation D promulgated by the Securities and Exchange Commission under the 
Securities Act, and that the Company's reliance on such exemption is 
predicated on FSC Corp.'s representations set forth herein.  FSC Corp. 
realizes that the basis for the exemption may not be present if, 
notwithstanding such representations, FSC Corp. has in mind merely acquiring 
any of the Securities for a fixed or determinable period in the future, or 
for a market rise, or for sale if the market does not rise.  FSC Corp. has no 
such intention.

6.4  RECEIPT OF INFORMATION. FSC Corp. believes it has received all the 
information it considers necessary or appropriate for deciding whether to 
purchase this Warrant.  FSC Corp. further represents that it has had an 
opportunity to ask questions and receive answers from the Company regarding 
the terms and conditions of the offering of this Warrant and the business, 
properties, prospects and financial condition of the Company and to obtain 
additional information (to the extent the Company possessed such information 
or could acquire it without unreasonable effort or expense) necessary to 
verify the accuracy of any information furnished to it or to which it had 
access.

6.5  INVESTMENT EXPERIENCE. FSC Corp. represents that it is experienced in 
evaluating and investing in securities of companies in the development stage 
and acknowledges that it is able to fend for itself, can bear the economic 
risk of its investment, and has such knowledge and experience in financial or 
business matters that it is capable of evaluating the merits and risks of the 
investment in this Warrant.  FSC Corp. also represents it has not been 
organized for the purpose of acquiring this Warrant.

                                     8

<PAGE>

6.6  RESTRICTED SECURITIES. FSC Corp. understands that this Warrant and the 
Securities are characterized as "restricted securities" under the federal 
securities laws inasmuch as they are being acquired from the Company in a 
transaction not involving a public offering and that under such laws and 
applicable regulations this Warrant and the Securities may be resold without 
registration under the Securities Act only in certain limited circumstances.  
FSC Corp. has no need for liquidity of its investment in this Warrant or the 
Securities.  In this connection, FSC Corp. represents that it is familiar 
with Securities and Exchange Commission Rule 144, as presently in effect, and 
understands the resale limitations imposed thereby and by the Securities Act.

6.7  LEGENDS. To the extent applicable, any certificates for the shares of 
Series D Preferred Stock issued upon exercise of this Warrant and the shares 
of Common Stock issued upon conversion of such Series D Preferred Stock shall 
be endorsed with the legends set forth below, and FSC Corp. covenants that, 
except to the extent such restrictions are waived by the Company, FSC Corp. 
shall not dispose of any interest in any of the shares of Series D Preferred 
Stock issued upon exercise of this Warrant or the shares of Common Stock 
issued upon conversion of such Series D Preferred Stock without complying 
with the restrictions on transfer described in the legends endorsed on such 
certificates:

                6.7.1  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE

UNDER SUCH ACT, OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL,
SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
REQUIRED.

                6.7.2    Any legend required by (i) any other agreement with the
Company to which FSC Corp. is a party or (ii) the securities laws of any state
or other governmental or regulatory agency having authority over the issuance of
the shares of Series D Preferred Stock issued upon exercise of this Warrant or
the shares of Common Stock issued upon conversion of such Series D Preferred
Stock.

          7.    REPLACEMENT OF WARRANT.  On receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of any such loss, theft or
destruction of this Warrant, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver to FSC Corp., in lieu thereof, a new Warrant of
like tenor.

          8.    NO RIGHTS OR LIABILITY AS A STOCKHOLDER.  This Warrant does not
entitle FSC Corp. hereof to any voting rights or other rights as a stockholder
of the Company.  No provisions hereof, in the absence of affirmative action by
FSC Corp. to purchase the Series D Preferred Stock of the Company, and no
enumeration herein of the rights or privileges of FSC Corp., shall give rise to
any liability of FSC Corp. as a stockholder of the Company.

Revolving Credit Loan in an equivalent amount and, to the extent so financed,
the Borrower's obligation to make such payment shall be discharged and replaced

degree with requirements of the Letter of Credit.

     (ii)  The Bank shall have no liability or responsibility by reason of or
in connection with the issuance or transfer of any Letter of Credit by the Bank
or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in clause (e)(i) above), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Bank; PROVIDED that the foregoing shall not be construed to excuse the Bank from
liability to the Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the
Borrower to the extent permitted by applicable law) suffered by the Borrower
that are caused by the Bank's gross negligence or wilful misconduct when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof.  Subject in all respects to the foregoing,
the parties hereto expressly agree that:

          (A)    the Bank may accept documents that appear on their face to be
     in substantial compliance with the terms of a Letter of Credit without
     responsibility for further investigation, regardless of any notice or
     information to the contrary, and may make payment upon presentation of
     documents that appear on their face to be in substantial compliance with
     the terms of such Letter of Credit;

          (B)    the Bank shall have the right, in its sole discretion, to
     decline to accept such documents and to make such payment if such documents
     are not in strict compliance with the terms of such Letter of Credit; and

          (C)    this clause (e)(ii) shall establish the standard of care to be
     exercised by the Bank when determining whether drafts and other documents
     presented under a Letter of Credit comply with the terms thereof (and the
     parties hereto hereby waive, to the extent permitted by applicable law, any
     standard of care inconsistent with the foregoing).

     (f)   DISBURSEMENT PROCEDURES.  The Bank shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for
payment under any Letter of Credit.  The Bank shall promptly notify the Borrower
by telephone (confirmed by telecopy) of such demand for payment and whether the
Bank has made or will make an LC Disbursement thereunder; PROVIDED that any
failure to give or delay in giving such notice shall not relieve the Borrower of
its obligation to reimburse the Bank with respect to any such LC Disbursement.

     (g)   INTERIM INTEREST.  If the Bank shall make any LC Disbursement in
respect of any Letter of Credit, then, unless the Borrower shall reimburse such
LC Disbursement in full on the date such LC Disbursement is made, the unpaid
amount thereof shall bear interest, for each day from and including the date
such LC Disbursement is made to but excluding the date that the Borrower
reimburses such LC Disbursement, at the rate per annum then applicable to Base
Rate Revolving Credit Loans; PROVIDED that, if the Borrower fails to reimburse
such LC Disbursement 

                                    -20-

<PAGE>

when due pursuant to paragraph (d) of this Section 2.7, then interest at the 
Post-Default Rate shall accrue on the unpaid amount thereof.

     (h)   CASH COLLATERALIZATION.  If an Event of Default shall occur and be
continuing and the Borrower receives notice from the Bank demanding the deposit
of cash collateral pursuant to this paragraph, or the Borrower shall immediately
deposit with the Bank an amount in cash equal to the LC Exposure as of such date
plus any accrued and unpaid interest thereon; PROVIDED that the obligation to
deposit such cash collateral shall become effective immediately, and such
deposit shall become immediately due and payable, without demand or other notice
of any kind, upon the occurrence of any Event of Default.  Such deposit shall be
held by the Bank as collateral in the first instance for the LC Exposure under
this Agreement and thereafter for the payment of any other obligations of the
Borrower hereunder.

     2.8   FEES.

     (a)   The Borrower agrees to pay to the Bank on the daily average unused
amount of the respective Revolving Credit Commitment, during each fiscal quarter
from and including the Closing Date any unused commitment fees equal to .50% per
annum.  Accrued commitment fees shall be payable in arrears on each Quarterly
Date commencing on the first such date occurring after the date hereof.  All
commitment fees shall be computed on the basis of a year of 360 days and shall
be payable for the actual number of days elapsed (including the first day but
excluding the last day).

     (b)   The Borrower agrees to pay an additional fee of $100,000 which is
due on the Closing Date but payable $50,000 at closing and an additional $25,000
on the first anniversary of the Closing Date and $25,000 on the second
anniversary of the Closing Date; provided that the entire remaining amount of
the additional fee shall be due and payable upon the repayment of the
Commitments.

     (c)   The Borrower agrees to pay to the Bank an additional fee (the
"Prepayment Penalty") as follows: (i) 3% of the amount prepaid if the Term Loan
is paid by the first anniversary of the Closing Date, (ii) 2% of the amount
prepaid if the Term Loan is paid on and after the first anniversary of the
Closing Date and prior to the second anniversary of the Closing Date and (iii)
1% of the amount prepaid if paid on or after the second anniversary of the
Closing Date.

     (d)   The Borrower agrees to pay the Bank with respect to Letters of
Credit a fee per annum equal 2.00% of the average daily amount of the Bank's LC
Exposure (excluding any portion thereof attributable to unreimbursed LC
Disbursements).  Accrued fees shall be payable in arrears on each Quarterly Date
and on the date the Revolving Credit Commitment terminates, commencing on the
first such date to occur after the date hereof, PROVIDED that any such fees
accruing after the date on which the Revolving Credit Commitment terminates
shall be payable on demand.

     (e)   All fees payable hereunder shall be paid on the dates due, in
immediately available funds.  Fees paid shall not be refundable under any
circumstances, absent manifest error in the determination thereof.

                                    -21-

     2.9   INTEREST.

     (a)   The Loans comprising Revolving Credit Loans and Term Loans at the
Base Rate shall bear interest at a rate per annum equal to the Adjusted Base
Rate plus 1.00% per annum or the Adjusted Base Rate plus 1.50% for all Revolving
Credit Loans  if there is no pledge of the stock of the Borrower to the Bank.

     (b)   The Loans comprising Revolving Credit Loans and Term Loans at the
LIBO Rate shall bear interest of a rate per annum equal to the Adjusted LIBO
Rate plus 3.50% per annum; provided that, if there is no pledge of the stock of
the Borrower to the Bank, Revolving Credit Loans which are at the LIBO Rate
shall bear interest at a rate per annum equal to the Adjusted LIBO Rate plus
4.00% per annum.

     (c)   Notwithstanding the foregoing all obligations shall bear interest 
until paid in full at the Adjusted Base Rate plus 3.00% per annum (the 
"Post-Default Rate") when any Event of Default shall have occurred and be 
continuing after as well as before judgment.

     (d)   The Borrower shall pay the Bank a late payment fee equal to 5% of
the amount of any payment of principal or interest or any mandatory prepayment
not received by the Bank within ten (10) days of the date required for such
payment under this Agreement.

     (e)   Accrued interest on each Loan shall be payable quarterly in arrears
on each Interest Payment Date for such Loan; PROVIDED that (i) interest accrued
at the Post-Default Rate and any late payment fee shall be payable on demand,
(ii) in the event of any repayment or prepayment of any LIBOR Loan (or the
repayment or prepayment in full of the Term Loans), accrued interest on the
principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment, (iii) in the event of any conversion of any LIBOR Loan
prior to the end of the current Interest Period therefor, accrued interest on
such Loan shall be payable on the effective date of such conversion and (iv) all
accrued interest on Revolving Credit Loans shall be payable upon expiration of
the Revolving Credit Availability Period.

     (f)   All interest hereunder shall be computed on the basis of a year of
360 days, and in each case shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).  The applicable
Adjusted Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the
Bank, and such determination shall be conclusive absent manifest error.

     2.10  ALTERNATIVE RATE OF INTEREST.

     (a)   if the Bank determines (which determination shall be conclusive
absent manifest error) that adequate and reasonable means do not exist for
ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such
Interest Period; or

     (b)   if the Bank determines that the Adjusted LIBO Rate or the LIBO Rate,
as applicable, will not adequately and fairly reflect the cost to the Bank of
making or maintaining Loans of a Class included in a Borrowing for any Interest
Period; 

                                    -22-

<PAGE>

     (c)   then the Bank shall give notice thereof to the Borrower by telephone
or telecopy as promptly as practicable thereafter and, until the Bank notifies
the Borrower that the circumstances giving rise to such notice no longer exist,
(i) any Interest Election Request that request the conversion of any Borrowing
to, or continuation of any Borrowing as, a LIBOR Borrowing shall be ineffective
and (ii) if any Borrowing Request requests a LIBOR Borrowing, such Borrowing
shall be made as a Base Rate Borrowing.

     2.11  INCREASED COSTS. 

     (a)   If any Change in Law shall:

          (i)    impose, modify or deem applicable any reserve, special deposit
     or similar requirement against assets of, deposits with or for the account
     of, or credit extended by, the Bank (except any such reserve requirement
     reflected in the Adjusted LIBO Rate); or

          (ii)   impose on the Bank or the London interbank market any other
     condition affecting this Agreement or LIBOR Loans made by the Bank or any
     Letter of Credit;

and the result of any of the foregoing shall be to increase the cost to the Bank
of making or maintaining any LIBOR Loan (or of maintaining its obligation to
make any such Loan) or to increase the cost to the Bank, issuing or maintaining
any Letter of Credit or to reduce the amount of any sum received or receivable
by the Bank (whether of principal, interest or otherwise), then the Borrower
will pay to the Bank, such additional amount or amounts as will compensate the
Bank for such additional costs incurred or reduction suffered.

     (b)   If the Bank reasonably determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such the Bank's capital or on the capital of the Bank holding company, if
any, as a consequence of this Agreement or the Loans made by, or participations
in Letters of Credit held by, the Bank or the Letters of Credit issued to a
level below that which such the Bank's holding company could have achieved but
for such Change in Law (taking into consideration the Bank's policies and the
policies of the Bank's  holding company with respect to capital adequacy), then
from time to time the Borrower will pay to the Bank, such additional amount or
amounts as will compensate the Bank, or such the Bank's  holding company, for
any such reduction suffered.

     (c)   A certificate of the Bank setting forth the amount or amounts
necessary to compensate the Bank or its holding company, as the case may be, as
specified in paragraph (a) or (b) of this Section 2.11 and setting forth in
reasonable detail the basis for such claim and a calculation of the amount
payable to the Bank shall be delivered to the Borrower and shall be conclusive
so long as it reflects a reasonable basis for the calculation of the amounts set
forth therein and does not contain any manifest error.  The Borrower shall pay
the Bank the amount shown as due on any such certificate within 10 days after
receipt thereof.

     (d)   Failure or delay on the part of the Bank to demand compensation
pursuant to this Section 2.11 shall not constitute a waiver of the Bank's right
to demand such compensation; PROVIDED that the Borrower shall not be required to
compensate pursuant to this Section 2.11 for 

                                    -23-

<PAGE>

any increased costs or reductions incurred more than six months prior to the
date that the Bank, notifies the Borrower of the Change in Law giving rise to
such increased costs or reductions and of the Bank's intention to claim
compensation therefor; PROVIDED FURTHER that, if the Change in Law giving rise
to such increased costs or reductions is (i) retroactive and (ii) occurred
within such six-month period, then the six-month period referred to above may be
extended to include the period of retroactive effect thereof, but in no event
any period prior to the Closing Date.

     2.12  BREAK FUNDING PAYMENTS.

     (a)   In the event of (i) the payment of any principal of any LIBOR Loan
other than on the last day of an Interest Period applicable thereto (including
as a result of an Event of Default), (ii) the conversion of any LIBOR Loan other
than on the last day of the Interest Period applicable thereto or, (iii) the
failure to borrow, convert, continue or prepay any LIBOR Loan on the date
specified in any notice delivered pursuant hereto (regardless of whether such
notice is permitted to be revocable and is revoked in accordance herewith) in
any such event, the Borrower shall compensate the Bank for the loss, cost and
expense attributable to such event.

     (b)   In the case of a LIBOR Loan, the loss to the Bank attributable to
any such event shall be deemed to include an amount determined by the Bank to be
equal to the excess, if any, of

          (i)    the amount of interest that the Bank would pay for a deposit
     equal to the principal amount of such Loan for the period from the date of
     such payment, conversion, failure or assignment to the last day of the then
     current Interest Period for such Loan (or, in the case of a failure to
     borrow, convert or continue, the duration of the Interest Period that would
     have resulted from such borrowing, conversion or continuation) if the
     interest rate payable on such deposit were equal to the Adjusted LIBO Rate
     for such Interest Period,

     OVER

          (iv) the amount of interest that such Lender would earn on such 
     principal amount for such period if the Bank were to invest such 
     principal amount for such period at the interest rate that would be bid 
     by the Bank (or an affiliate of the Bank) for U.S. dollar deposits from 
     other banks in the eurodollar market at the commencement of such period.

     (c)   A certificate of the Bank setting forth any amount or amounts that
such Lender is entitled to receive pursuant to this Section 2.12 and setting
forth in reasonable detail the basis for such claim and a calculation of the
amount payable to such Lender shall be delivered to the Borrower and shall be
conclusive absent manifest error.  The Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

     2.13  TAXES.

     (a)   Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Taxes; PROVIDED that if the Borrower shall be required to deduct any Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions the Bank 

                                    -24-

<PAGE>

receives an amount equal to the sum it would have received had no such 
deductions been made, (ii) the Borrower shall make such deductions and (iii) 
the Borrower shall pay the full amount deducted to the relevant Governmental 
Authority in accordance with applicable law.

     (b)   In addition, the Borrower shall pay any Taxes to the relevant
Governmental Authority in accordance with applicable law.

     (c)   The Borrower shall indemnify the Bank, within 30 days after 
written demand therefor, for the full amount of any Taxes which may become 
payable as described in this Section 2.13(a) (other than taxes on income of 
the Bank) paid by the Bank (and any penalties, interest and reasonable 
expenses arising therefrom or with respect thereto during the period prior to 
the Borrower making the payment demanded under this paragraph (c)), whether 
or not such Taxes were correctly or legally imposed or asserted by the 
relevant Governmental Authority. A certificate as to the amount of such 
payment or liability delivered to the Borrower by the Bank shall be 
conclusive absent manifest error.

     (d)   As soon as practicable after any payment of such Taxes by the
Borrower to a Governmental Authority, the Borrower shall deliver to the Bank the
original or a certified copy of a receipt issued by such Governmental Authority
evidencing such payment under Section 2.13(a), a copy of the return reporting
such payment or other evidence of such payment reasonably satisfactory to the
Bank.

     2.14  PAYMENTS GENERALLY.

     (a)   The Borrower shall make each payment required to be made by them
hereunder prior to 4:00 p.m., Boston, Massachusetts time, on the date when due,
in immediately available funds, without set-off or counterclaim.  Any amounts
received after such time on any date may, in the discretion of the Bank, be
deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon.  All such payments shall be made to the Bank at
such of its offices in Boston, Massachusetts as shall be notified to the
Borrower from time to time.  If any payment hereunder shall be due on a day that
is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension.  All
payments hereunder shall be made in U.S. dollars.

     (b)   If at any time insufficient funds are received by and available to
the Bank to pay fully all amounts of principal, interest and fees then due
hereunder under any circumstances, including, without limitation during, or as a
result of the exercise by the Bank of remedies under the Collateral Documents
and applicable law, such funds shall be applied (i) first, to pay interest and
fees then due hereunder and (ii) second, to pay principal.

     (c)   The Borrower authorizes the Bank to charge its deposit accounts
maintained by the Borrower with the Bank any Obligation due hereunder when due.

                                   ARTICLE III

                           REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Bank, as to itself, that:

     3.1   ORGANIZATION; POWERS.  The Borrower is duly organized, validly
existing and in good standing under the laws of its jurisdiction of
organization.  The Borrower has all requisite power and authority under its
organizational documents to carry on its business as now conducted and, except
where the failure to be so qualified or in good standing, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect, is qualified to do business in, and is in good standing in, every
jurisdiction where such qualification is required.

     3.2   AUTHORIZATION; ENFORCEABILITY.  The Transactions are within the
corporate power of the Borrower and have been duly authorized by all necessary
corporate and, if required, stockholder action on the part of the Borrower. 
This Agreement has been duly executed and delivered by the Borrower and
constitutes a legal, valid and binding obligation of such Borrower, enforceable
in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally
and subject to general principles of equity, regardless of whether considered in
a proceeding in equity or at law.

     3.3   GOVERNMENTAL APPROVALS; NO CONFLICTS.  Except as set forth on
SCHEDULE 3.3, the Transactions (a) do not require any consent or approval of,
registration or filing with, or any other action by, any Governmental Authority
that has not been obtained, (b) will not violate any applicable law, policy or
regulation or the charter, by-laws or other organizational documents of the
Borrower or any order of any Governmental Authority, (c) will not violate or
result in a default under any indenture, agreement or other instrument binding
upon the Borrower, or any of its assets, or give rise to a right thereunder to
require any payment to be made by the Borrower, and (d) except for the Liens
created by the Collateral Documents, will not result in the creation or
imposition of any Lien on any asset of the Borrower.

     3.4   FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE.

     (a)   The Borrower has heretofore delivered to the Bank the following
financial statements:

          (i)    The audited balance sheet and statement of earnings (loss),
     stockholder's deficit and cash flows of the Borrower, as of and for fiscal
     years ending December 28, 1997 and December 29, 1996, respectively,
     accompanied by an opinion of Deloitte, Touche LLP, independent public
     accountants;

          (ii)   the unaudited balance sheet and statements of earnings (loss),
     stockholders' deficit and cash flows of the Borrower as of and for the
     three months ending four-week periods ended March 29, 1998, certified by a
     Senior Officer that such financial statements fairly present (subject to
     normal year-end audit adjustments) the financial condition of the Borrower
     as at such dates and the results of the operations of 

                                    -26-

<PAGE>


     the Borrower for the periods ended on such dates and that all such 
     financial statements, including the related schedules and notes thereto 
     have been prepared in accordance with GAAP applied consistently throughout
     the periods involved; and 

Such financial statements present fairly, in all material respects, the
respective actual or pro forma combined financial position and results of
operations and cash flows of the respective entities as of such respective dates
and for such periods in accordance with GAAP, subject to year-end audit
adjustments and the absence of footnotes in the case of such unaudited or pro
forma statements and are accurate and complete in all respects.

     (b)   Since the last day of the Borrower's most recent audited period,
there has been no material adverse change in the business, assets, operations,
prospects or condition, financial or otherwise, of the Borrower.

     (c)   The Borrower has furnished to the Bank annual combined financial
projections dated as of August  1997 and covering fiscal years 1998 through
2001.  Such financial projections are based on good faith estimates and
assumptions made by the Borrower and its management, and on the Closing Date,
such parties believed that the projections were reasonable and attainable, it
being recognized by the Bank, however, that projections as to future events are
not to be viewed as facts and that actual results during the period or periods
covered by the projections may differ from the projected results and that the
differences may be material.

     (d)   The Borrower does not have on the date hereof any contingent
liabilities, liabilities for taxes, unusual forward or long-term commitments or
unrealized or anticipated losses from any unfavorable commitments in each case
that are material, except as referred to or reflected or provided for in the
balance sheets referred to above or as provided for in SCHEDULE 3.4 annexed
hereto, or as otherwise expressly provided in this Agreement, or as referred to
or reflected or provided for in the financial statements described in this
Section 3.4.

     3.5   PROPERTIES.

     (a)   Except as set forth on SCHEDULE 3.5, the Borrower has good title to,
or valid, subsisting and enforceable leasehold interests in, all of its Property
material to its business.

     (b)   Except as set forth on Schedule 3.5, the Borrower owns, or is
licensed to use, all trademarks, service marks, tradenames, copyrights, patents
and other intellectual property ("PROPRIETARY RIGHTS") material to its business
and the use thereof by the Borrower does not infringe upon the rights of any
other Person, except for any such infringements that, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect.  All such trademark applications and registrations, trademarks,
registered copyrights, patents and patent applications which are owned by or
licensed to the Borrower are listed on SCHEDULE 3.5 annexed hereto ("REGISTERED
RIGHTS").

                                    -27-

<PAGE>

     3.6   LITIGATION AND ENVIRONMENTAL MATTERS.

     (a)   There are no actions, suits or proceedings by or before any
arbitrator or Governmental Authority pending against or, to the knowledge of any
of the Borrower, threatened against or affecting the Borrower (i) as to which
there is a reasonable possibility of an adverse determination and that, if
adversely determined, could reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Effect (other than the Disclosed
Matters) or (ii) that involve any of the Loan Documents or the Transactions.

     (b)   Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, the Borrower (i) has not failed
to comply with any Environmental Law or to obtain, maintain or comply with any
permit, license or other approval required under any Environmental Law, (ii) has
not become subject to any Environmental Liability, (iii) has not received notice
of any claim with respect to any Environmental Liability or any inquiry,
allegation, notice or other communication from any Governmental Authority
concerning its compliance with any Environmental Law or (iv) does not know of
any basis for any Environmental Liability.

     (c)   Since the date of this Agreement, there has been no change in the
status of the Disclosed Matters that, individually or in the aggregate, has
resulted in, or materially increased the likelihood of, a Material Adverse
Effect.

     3.7   COMPLIANCE WITH LAWS AND AGREEMENTS.  The Borrower is in compliance
with all laws, regulations, policies and orders of any Governmental Authority
applicable to it or its property and all indentures, agreements and other
instruments binding upon it or its property, except where the failure to do so,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect.

     3.8   INVESTMENT AND HOLDING COMPANY STATUS.  Neither the Borrower nor any
of its Affiliates is (a) an "investment company" as defined in, or subject to
regulation under, the Investment Company Act of 1940, as amended, (b) a "holding
company" as defined in, or subject to regulation under, the Public Utility
Holding Company Act of 1935, as amended or (c) a "bank holding company" as
defined in, or subject to regulation under, the Bank Holding Company Act of
1956, as amended.

     3.9   TAXES.  The Borrower has timely filed or caused to be filed all Tax
returns and reports required to have been filed and has paid or caused to be
paid all Taxes required to have been paid by it, except (a) Taxes that are being
contested in good faith by appropriate proceedings and for which such Borrower
has set aside on its books adequate reserves with respect thereto in accordance
with GAAP or (b) to the extent that the failure to do so could not reasonably be
expected to result in a Material Adverse Effect.

     3.10  ERISA.  No ERISA Event has occurred or is reasonably expected to 
occur that, when taken together with all other such ERISA Events for which 
liability is reasonably expected to occur, could reasonably be expected to 
result in a Material Adverse Effect.  The present value of all accumulated 
benefit obligations under each Plan (based on the assumptions used for 
purposes of Statement of Financial Accounting Standards No. 87) did not, as 
of the date of the 

                                    -28-

<PAGE>

most recent financial statements reflecting such amounts, exceed the fair 
market value of the assets of such Plan.

     3.11  DISCLOSURE.  As of the Closing Date, the Borrower has disclosed to
the Bank all agreements, instruments and corporate or other restrictions to
which the Borrower is subject after the Closing Date, and all other matters
known to the Borrower, that, individually or in the aggregate, could reasonably
be expected to result in a Material Adverse Effect.  A list of the senior
management of the Borrower  is set forth on SCHEDULE 3.11 annexed hereto.  The
information, reports, financial statements, exhibits and schedules furnished in
writing by or on behalf of the Borrower to the Bank on or prior to the Closing
Date in connection with the negotiation, preparation or delivery of this
Agreement and the other Loan Documents or included herein or therein or
delivered pursuant hereto or thereto, when taken as a whole do not contain any
untrue statement of material fact or omit to state any material fact necessary
to make the statements herein or therein, in light of the circumstances under
which they were made, not misleading.  All written information furnished after
the Closing Date by the Borrower to the Bank in connection with this Agreement
and the other Loan Documents and the transactions contemplated hereby and
thereby will be true, complete and accurate in every material respect, or (in
the case of projections) based on reasonable estimates, on the date as of which
such information is stated or certified.  There is no fact known to the Borrower

including the reasonable fees, charges and disbursements of any counsel for the
Bank, in connection with the enforcement or protection of its rights in

charges and disbursements of any counsel for any Indemnitee and settlement
costs, incurred by or asserted against any Indemnitee arising out of, in

investigation or proceeding relating to any of the foregoing, whether based 
on contract, tort or any other theory and regardless of whether any 
Indemnitee is a party thereto; provided that such indemnity shall not, as to 
any Indemnitee, be available to the extent that such losses, claims, damages, 
liabilities or related expenses (are determined by a court of competent 
jurisdiction by final and non-appealable judgment to have) resulted from the 
gross negligence or wilful misconduct of such Indemnitee.

     (c)   To the extent permitted by applicable law, the Borrower shall not
assert, and the Borrower hereby waives, any claim against any Indemnitee, on any
theory of liability, for special, indirect, consequential or punitive damages

instrument contemplated hereby or thereby, the Transactions, any Loan or Letter
of Credit or the use of the proceeds thereof.

consent shall be null and void).  Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

     (b)   The Bank may assign all of its rights and obligations under this
Agreement (including its Commitments and the Loans at the time owing to it),
subject to the consent of the Borrower (so long as no Default exists), which
consent shall not be unreasonably withheld.

     (c)   Upon acceptance of an assignment and from and after the effective
date specified in such assignment, the assignee thereunder shall be a party
hereto and, to the extent of the interest assigned by such assignment, have the
rights and obligations of the Bank under this Agreement, and the Bank shall, to
the extent of the interest assigned by such assignment, be released from its
obligations under this Agreement (and, in the case of an assignment covering all
of the Bank's rights and obligations under this Agreement, the Bank shall cease
to be a party hereto but shall continue to be entitled to the benefits of
Sections 2.10, 2.12 and 8.3).

     (d)   The Bank may sell participations to one or more banks or other
entities (a "PARTICIPANT") in all or a portion of the Bank's rights and

                                    -47-

<PAGE>

the Bank's obligations under this Agreement shall remain unchanged, (ii) the 
Bank shall remain solely responsible to the other parties hereto for the 
performance of such obligations and (iii) the Borrower shall continue to deal 
solely and directly with the Bank in connection with the Bank's rights and 
obligations under this Agreement. The Borrower agrees that each Participant 
shall be entitled to the benefits of Sections 2.8, 2.9 and 2.10 to the same 
extent as if it were the Bank and had acquired its interest by assignment 
pursuant to paragraph (b) of this Section 8.4.

     (e)   The Bank may at any time  pledge or assign a security interest in
all or any portion of its rights under this agreement to secure obligations of
the Bank, including any such pledge or assignment to a Federal Reserve Bank and
this Section shall not apply to any such pledge or assignment of a security
interest.

     8.5   SURVIVAL.  All covenants, agreements, representations and warranties
made by the Borrower herein and in the other Loan Documents, and in the
certificates or other instruments delivered in connection with or pursuant to
this Agreement and the other Loan Documents, shall be considered to have been
relied upon by the other parties hereto and shall survive the execution and
delivery of this Agreement and the other Loan Documents and the making of any
Loans and shall continue in full force and effect so long as the principal of or
any accrued interest on any Loan or any fee or any other amount payable under
this Agreement or the other Loan Documents is outstanding and so long as the
Commitments have not expired or terminated.  The provisions of Sections 2.10,
2.12 and 8.3 shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the Loans
and the Commitments or the termination of this Agreement or any other Loan
Document or any provision hereof or thereof.

     8.6   COUNTERPARTS; INTEGRATION; REFERENCES TO AGREEMENT; EFFECTIVENESS. 
This Agreement may be executed in counterparts (and by different parties hereto
on different counterparts), each of which shall constitute an original, but all
of which when taken together shall constitute a single contract.  This Agreement
and the collateral Documents constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof.  Whenever there is a reference in any Collateral Document or UCC
Financing Statement to the "Credit Agreement" to which the Bank and the Borrower
are parties, such reference shall be deemed to be made to this Agreement among
the parties hereto.  Except as provided in Section 4.1, this Agreement shall
become effective when it shall have been executed by the Bank and when the Bank
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns.  Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

     8.7   SEVERABILITY.  Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability
without affecting the validity, legality and enforceability of the remaining
provisions hereof; and the invalidity of a particular provision in a particular
jurisdiction shall not invalidate such provision in any other jurisdiction.

     5.    SPECIAL WARRANTIES AND COVENANTS OF THE DEBTOR.  The Debtor hereby
warrants and covenants to the Bank:  

           (a)   The address shown at the beginning of this Agreement is the
current principal place of business of the Debtor, and all of the Debtor's
current additional places of business, if any, and the locations of all of the
Collateral currently are listed in SCHEDULE I.  The Debtor will not change its
principal or any other place of business, or the location of any Collateral from
the locations set forth in SCHEDULE I, or make any change in the Debtor's name
or conduct the Debtor's business operations under any fictitious business name
or trade name, without, in any such case, at least thirty (30) days' prior
written notice to the Bank.

           (b)   Except for the security interest created hereunder and as
otherwise expressly disclosed in or permitted by the Credit Agreement, the
Debtor is the owner of the Collateral free from any lien, security interest or
encumbrance and the Debtor will defend the Collateral against all claims and
demands of all persons at any time claiming the same or any interest therein.

           (c)   Except as permitted by the Credit Agreement or otherwise
consented to in writing by the Bank, the Debtor will not sell or otherwise
dispose of any of the Collateral or any interest therein other than in the
ordinary course of business nor will the Debtor create, incur or permit to exist
any mortgage, lien, charge, encumbrance or security interest whatsoever with
respect to the Collateral.

           (d)   Except for Collateral that is obsolete or no longer used in
the Debtor's business, the Debtor will keep the Collateral in good order and
repair (normal wear excepted) and adequately insured at all times in accordance
with the provisions of the Credit Agreement.  The Debtor will pay promptly when
due all taxes and assessments on the Collateral or for its use or operation,
except for taxes and assessments permitted to be contested as provided in
Section 5.4 of the Credit Agreement.  The Bank may at its option discharge any
taxes, liens, security interests or other encumbrances to which any Collateral
is at any time subject, and may, upon the failure of the Debtor to do so in
accordance with the Credit Agreement, purchase insurance on any Collateral and
pay for the repair, maintenance or preservation thereof, and the Debtor agrees
to reimburse the Bank on demand for any payments or expenses incurred by the
Bank pursuant to the foregoing authorization and any unreimbursed amounts shall
constitute Secured Obligations for all purposes hereof.

           (e)   The Debtor will promptly execute and deliver to the Bank such
financing statements, certificates and other documents or instruments as may be
necessary to enable the Bank to perfect or from time to time renew the security
interest granted hereby, including, without limitation, such financing
statements, certificates and other documents as may be necessary to perfect a
security interest in any additional Collateral hereafter acquired by the Debtor
or in any replacements or proceeds thereof.  The Debtor authorizes and appoints
the Bank 

                                      -3-

<PAGE>

to execute such financing statements, certificates and other documents 
pertaining to the Bank security interest in the Collateral in its stead, with 
full power of substitution, as the Debtor's attorney in fact.  The Debtor 
further agrees that a carbon, photographic or other reproduction of a 
security agreement or financing statement is sufficient as a financing 
statement under this Agreement.

           (f)   The Debtor will give the Bank notice of each office at which 
records of the Debtor pertaining to all intangible items of Collateral are 
kept. Except as may be provided in such notice, the records concerning all 
intangible Collateral are and will be kept at the address shown at the 
beginning of this Agreement as the principal place of business of the Debtor.

     6.    FIXTURES, ETC.  Debtor will take all such reasonable action or
actions as may be necessary consistent with past business practices to prevent
any of the Collateral from becoming fixtures and, in any event, subject to the
terms of real property leases.

Agreement upon the happening of any of the following events or conditions
(herein called "Events of Default"):

           (a)   Default shall be made in the due and punctual payment of any
principal of or premium, if any, or interest on any of the Secured Obligations

date fixed for any prepayment or installment or by declaration or acceleration
or otherwise) and such default shall continue beyond the expiration of the
applicable period of grace, if any; or

           (b)   The breach, violation or other non-performance of any term,
covenant, condition, agreement or obligation of the Debtor contained herein; or

           (c)   Any other Event of Default (as defined or provided in the
Credit Agreement) shall occur.

remedied or cured, the Bank shall have the following rights and remedies:

           (a)   All rights and remedies provided by law, including, without
limitation, those provided by the Uniform Commercial Code;

           (b)   All rights and remedies provided in this Agreement; and

document or instrument pertaining to the Secured Obligations.

                                      -4-

<PAGE>

     9.    RIGHT OF THE BANK TO DISPOSE OF COLLATERAL, ETC.  Upon the
occurrence of any Event of Default, such Event of Default not having previously
been waived, remedied or cured, but subject to the provisions of the Uniform
Commercial Code or other applicable law, the Bank shall have the right to take
possession of the Collateral and, in addition thereto, the right to enter upon
any premises on which the Collateral or any part thereof may be situated and
remove the same therefrom.  The Bank may require the Debtor to make the
Collateral (to the extent the same is moveable) available to the Bank at a place
to be designated by the Bank which is reasonably convenient to both parties or
transfer any information related to the Collateral to the Bank by electronic
medium.  Unless the Collateral is perishable or threatens to decline speedily in
value or is of a type customarily sold on a recognized market, the Bank will
give the Debtor at least ten (10) days' prior written notice at the address of
the Debtor set forth above (or to such other address or addresses as the Debtor
shall specify in writing to the Bank) of the time and place of any public sale
thereof or of the time after which any private sale or any other intended
disposition thereof is to be made.  Any such notice shall be deemed to meet any
requirement hereunder or under any applicable law (including the Uniform
Commercial Code) that reasonable notification be given of the time and place of
such sale or other disposition.

     10.   CREDIT AGREEMENT.  Notwithstanding any other provision of this
Agreement, the rights of the parties hereunder are subject to the provisions of
the Credit Agreement, including the provisions thereof pertaining to the rights
and responsibilities of the Bank.

     11.   RIGHT OF THE BANK TO USE AND OPERATE COLLATERAL, ETC.  Upon the 
occurrence of any Event of Default, such Event of Default not having 
previously been waived, remedied or cured, but subject to the provisions of 
the Uniform Commercial Code or other applicable law, the Bank shall have the 
right and power to take possession of all or any part of the Collateral, and 
to exclude the Debtor and all persons claiming under the Debtor wholly or 
partly therefrom, and thereafter to hold, store, and/or use, operate, manage 
and control the same. Upon any such taking of possession, the Bank may, from 
time to time, at the expense of the Debtor, make all such repairs, 
replacements, alterations, additions and improvements to and of the 
Collateral as the Bank may deem proper. In any such case the Bank shall have 
the right to manage and control the Collateral and to carry on the business 
and to exercise all rights and powers of the Debtor in respect thereto as the 
Bank shall deem best, including the right to enter into any and all such 
agreements with respect to the operation of the Collateral or any part 
thereof as the Bank may see fit; and the Bank shall be entitled to collect 
and receive all rents, issues, profits, fees, revenues and other income of 
the same and every part thereof.  Such rents, issues, profits, fees, revenues 
and other income shall be applied to pay the expenses of holding and 
operating the Collateral and of conducting the business thereof, and of all 
maintenance, repairs, replacements, alterations, additions and improvements, 
and to make all payments which the Bank may be required or may elect to make, 
if any, for taxes, assessments, insurance and other charges upon the 
Collateral or any part thereof, and all other payments which the Bank may be 
required or authorized to make under any provision of this Agreement 
(including reasonable legal costs and attorneys' fees).  The remainder of 
such rents, issues, profits, fees, revenues and other income shall be applied 
as provided in Section 13.

     12.   COLLECTION OF ACCOUNTS RECEIVABLE, ETC.  At any time after an Event
of Default, upon notice to the Debtor from the Bank, all of the proceeds of the
Debtor's accounts receivable 

                                      -5-

<PAGE>

and all other proceeds of Collateral of any nature, whether now existing or 
hereafter arising, and domestic cash receipts in the Debtor's possession 
shall be paid into a lock box account with the Bank or under an agency 
agreement with other institutions, and after an Event of Default, the Bank 
may take any other steps which the Bank deems necessary or advisable to 
collect any or all such accounts receivable or other Collateral or proceeds 
thereof.

     13.   PROCEEDS OF COLLATERAL.  After deducting all costs and expenses of
collection, storage, custody, sale or other disposition and delivery (including
reasonable legal costs and attorneys' fees) and all other charges against the
Collateral, the residue of the proceeds of any such sale or disposition shall be
applied to the payment of the Secured Obligations in such order of priority as
the Bank shall determine and any surplus shall be returned to the Debtor or to
any person or party lawfully entitled thereto.  By way of enlargement and not by
way of limitation of the rights of the Bank under applicable law or the Loans,
Credit Agreement or Collateral Documents, but notwithstanding any provision of
the Loans, Credit Agreement or Collateral Documents to the contrary, the Bank
shall be entitled to allocate its application of the Collateral, and the
proceeds thereof, to the Secured Obligations (including without limitation
either or both of the Loans) in such proportions and in such order as the Bank,
in its sole discretion, shall decide.  In the event the proceeds of any sale,
lease or other disposition of the Collateral hereunder are insufficient to pay
all of the Secured Obligations in full, the Debtor will be liable for the
deficiency, together with interest thereon at the maximum rate provided in the
Credit Agreement, and the cost and expenses of collection of such deficiency,
including (to the extent permitted by law), without limitation, reasonable
attorneys' fees, expenses and disbursements.

     14.   WAIVERS, ETC.  The Debtor hereby waives presentment, demand, notice,
protest and, except as is otherwise provided herein, all other demands and
notices in connection with this Agreement or the enforcement of the Bank's
rights hereunder or in connection with any Secured Obligations or any
Collateral; consents to and waives notice of the granting of renewals,
extensions of time for payment or other indulgences to the Debtor or to any
account debtor in respect of any account receivable or to any other third party,
or substitution, release or surrender of any Collateral, the addition or release
of persons primarily or secondarily liable on any Secured Obligation or on any
account receivable or other Collateral, the acceptance of partial payments on
any Secured Obligation or on any account receivable or other Collateral and/or
the settlement or compromise thereof.  No delay or omission on the part of the
Bank in exercising any right hereunder shall operate as a waiver of such right
or of any other right hereunder.  Any waiver of any such right on any one
occasion shall not be construed as a bar to or waiver of any such right on any
future occasion.  THE DEBTOR FURTHER WAIVES ANY RIGHT IT MAY HAVE UNDER THE
CONSTITUTION OF THE COMMONWEALTH OF MASSACHUSETTS, UNDER THE CONSTITUTION OF ANY
STATE IN WHICH ANY OF THE COLLATERAL MAY BE LOCATED, OR UNDER THE CONSTITUTION
OF THE UNITED STATES OF AMERICA, TO NOTICE (OTHER THAN ANY REQUIREMENT OF NOTICE
PROVIDED HEREIN) OR TO A JUDICIAL HEARING PRIOR TO THE EXERCISE OF ANY RIGHT OR
REMEDY PROVIDED BY THIS AGREEMENT TO THE BANK AND WAIVES ITS RIGHTS, IF ANY, TO
SET ASIDE OR INVALIDATE ANY SALE DULY CONSUMMATED IN ACCORDANCE WITH THE
FOREGOING PROVISIONS HEREOF ON THE GROUNDS (IF SUCH BE THE CASE) THAT THE SALE
WAS CONSUMMATED WITHOUT A PRIOR JUDICIAL HEARING.  The Debtor's waivers under
this section have 

                                      -6-

<PAGE>

been made voluntarily, intelligently and knowingly and after the Debtor has 
been apprised and counseled by its attorneys as to the nature thereof and its 
possible alternative rights.

     15.   TERMINATION; ASSIGNMENT, ETC.  This Agreement and the security
interest in the Collateral created hereby shall terminate when all of the
Secured Obligations have been paid and finally discharged in full.  In such
event, the Bank agrees to execute appropriate releases of liens on the
Collateral.  No waiver by the Bank or by any other holder of Secured Obligations
of any Default shall be effective unless in writing nor operate as a waiver of
any other Default or of the same Default on a future occasion.  In the event of
a sale or assignment of part or all of the Secured Obligations by the Bank, the
Bank may assign or transfer its rights and interest under this Agreement in
whole or in part to the purchaser or purchasers of such Secured Obligations,
whereupon such purchaser or purchasers shall become vested with all of the
powers and rights of the Bank hereunder.

     16.   REINSTATEMENT.  Notwithstanding the provisions of Section 15, this
Agreement shall continue to be effective or be reinstated, as the case may be,
if at any time any amount received by the Bank in respect of the Secured
Obligations is rescinded or must otherwise be restored or returned by the Bank
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Debtor or upon the appointment of any intervener or conservator of, or
trustee or similar official for, the Debtor or any substantial part of its
properties, or otherwise, all as though such payments had not been made.

     17.   GOVERNMENTAL APPROVAL.  Prior to or, where permitted, upon the
exercise by the Bank of any power, right, privilege or remedy pursuant to this
Agreement which requires any consent, approval, registration, qualification or
authorization of any governmental authority or instrumentality, the Debtor at
the request of the Bank will execute and deliver, or will cause the execution
and delivery of, all applications, certificates, instruments and other documents
and papers that the Debtor may be reasonably required to obtain for such
governmental consent, approval, registration, qualification or authorization.

     18.   NOTICES.  All notices, consents, approvals, elections and other
communications hereunder shall be in writing (whether or not the other
provisions of this Agreement expressly so provide) and shall be deemed to have
been duly given if delivered in accordance with the terms of the Credit
Agreement.

     19.   MISCELLANEOUS.  This Agreement shall inure to the benefit of and be
binding upon the Bank and the Debtor and their respective successors and
assigns.  In case any provision in this Agreement shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining provisions hereof shall not in any way be affected or impaired
thereby.  This Agreement may be executed in any number of counterparts and by
the different parties hereto on separate counterparts, each of which shall be an
original, but all of which together shall constitute one instrument.

     20.   GOVERNING LAW; JURISDICTION; WAIVER OF JURY TRIAL.  This Agreement,
including the validity hereof and the rights and obligations of the parties
hereunder, shall be construed in 

                                      -7-

<PAGE>

accordance with and governed by the laws of the Commonwealth of Massachusetts 
(excluding its conflicts of laws principles).  The Debtor, to the extent that 
it may lawfully do so, hereby consents to service of process, and to be sued, 
in the Commonwealth of Massachusetts and consents to the jurisdiction of the 
courts of the Commonwealth of Massachusetts and the United States District 
Court for the District of Massachusetts, as well as to the jurisdiction of 
all courts to which an appeal may be taken from such courts, for the purpose 
of any suit, action or other proceeding arising out of any of the Secured 
Obligations or with respect to the transactions contemplated hereby, and 
expressly waives any and all objections it may have as to venue in any such 
courts.  The Debtor further agrees that a summons and complaint commencing an 
action or proceeding in any of such courts shall be properly served and shall 
confer personal jurisdiction if served personally or by certified mail to it 
at its address provided in Section 18 hereof or as otherwise provided under 
the laws of the Commonwealth of Massachusetts.

     THE DEBTOR IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY
PROCEEDING HEREAFTER INSTITUTED BY OR AGAINST THE DEBTOR IN RESPECT OF ITS
OBLIGATIONS HEREUNDER OR THE TRANSACTIONS CONTEMPLATED HEREBY.

                                      -8-

<PAGE>

Pledgor where permitted by law and agrees to do such further acts and things, 
and to execute and deliver to the Secured Party such additional assignments, 
agreements, powers and instruments, as the Secured Party may reasonably 
require to carry into effect the purposes of this Agreement or better to

remedies hereunder.  Pledgor shall, upon the reasonable request of the

the sole cost and expense of Pledgor. 

     Section 5.  REPRESENTATIONS AND WARRANTIES OF PLEDGOR.  Pledgor hereby
represents and warrants to the Secured Party as follows: 

          (a)  Pledgor is, and, as to Pledged Collateral acquired by it from
     time to time after the date hereof, Pledgor will be, the sole and exclusive
     owner or, as applicable, licensee of all Pledged Collateral (except insofar
     as another pledgor of such collateral to Secured Party is an owner or
     licensee of such Pledged Collateral).  The pledge and security interest
     created by this Agreement shall not at any time be subject to any prior
     lien, pledge, security interest, encumbrance, license, assignment,
     collateral assignment or charge of any kind, including, without limitation,
     any filing or agreement to file a financing statement as debtor under the
     UCC or any similar statute or any subordination arrangement in favor of any
     party other than Pledgor (collectively, "LIENS") and except as expressly
     permitted hereunder and under the Credit Agreement ("Credit Agreement
     Liens").  Pledgor further represents and warrants to the Secured Party that
     SCHEDULE A hereto, respectively, are true, correct and complete lists as of
     the date hereof.

          (b)  Pledgor has full corporate power, authority and legal right to
     pledge and grant a security interest in the Pledged Collateral in
     accordance with the terms of this Agreement and this Agreement constitutes
     the legal, valid and binding obligation of Pledgor, enforceable against
     Pledgor in accordance with its terms. 

          (c)  Except for filings with the United States Patent and Trademark
     Office, the filing of financing statements with the Secretary of State
     under the UCC and under applicable foreign law, no authorization, consent,
     approval, license, qualification or formal exemption from, nor any filing,
     declaration or registration with, any court (other than in connection with
     the exercise of judicial remedies), governmental agency or regulatory
     authority, or with any securities exchange or any other Person is required
     in connection with (1) the pledge by Pledgor of the Pledged Collateral
     pursuant to this Agreement, or the execution, delivery or performance by
     Pledgor of this Agreement, (2) the grant, and of a security interest
     (including the priority thereof when the appropriate filings have been made
     and accepted) in, the Pledged Collateral by Pledgor in the manner and for
     the purpose contemplated by this Agreement or the Credit Agreement; or (3)
     the exercise of the rights and remedies of the Secured Party created
     hereby. 

                                       4

<PAGE>

          (d)  Pledgor has made and will continue to make all necessary filings
     and recordations from time to time and use appropriate statutory notice to
     protect its interests in the Pledged Collateral, including, without
     limitation, recordations of all its interests in the Trademarks in the
     United States Patent and Trademark Office and in corresponding offices
     throughout the world and its claims to Copyrights in the United States
     Copyright Office, in each case including exclusive licenses and as
     otherwise requested from time to time by the Secured Party and in a manner
     consistent with prudent business practices. 

          (e)  Pledgor owns or has rights to use all the Pledged Collateral and
     all rights with respect to any of the foregoing used in, necessary for or
     material to Pledgor's business as currently conducted and as contemplated
     to be conducted pursuant to the Loan Documents.  To Pledgor's best
     knowledge after due inquiry, the use of such Pledged Collateral and all
     rights with respect to the foregoing by Pledgor does not infringe on the
     rights of any Person and no material claim has been made and remains
     outstanding that Pledgor's use of the Pledged Collateral does or may
     violate the rights of any third person. 

          (f)  Upon filings and the acceptance thereof in the appropriate
     offices under the UCC and in the United States Patent and Trademark Office
     and the United States Copyright Office, this Agreement will create a valid
     and duly perfected first priority lien and security interest in the United
     States in the Pledged Collateral on such property and to the extent that a
     lien can be perfected by such filings, subject to no liens other than
     Credit Agreement Liens.  This Agreement has been duly and validly executed
     and delivered by Pledgor, constitutes the legal, valid and binding
     obligation of Pledgor and is enforceable against Pledgor in accordance with
     its terms. 

          (g)  Pledgor has used and will continue to use proper statutory notice
     in connection with each of the trademarks.

     Section 6.  COVENANTS.  

          (a)   On a continuing basis, Pledgor will, at the expense of Pledgor,
subject to any prior licenses, Liens and restrictions make, execute, acknowledge
and deliver, and file and record in the proper filing and recording offices, all
such instruments or documents, including, without limitation, appropriate
financing and continuation statements, exclusive licenses and collateral
agreements, and take all such action (limited, as aforesaid, if applicable) as
may reasonably be deemed necessary or appropriate by the Secured Party (1) to
carry out the intent and purposes of this Agreement, (2) to assure and confirm
to the Secured Party the grant or perfection of a security interest in the
Pledged Collateral for the benefit of the Secured Party, and (3) during the
continuation of an Event of Default, to enable the Secured Party to exercise and
enforce their rights and remedies hereunder with respect to any Pledged
Collateral.  Without limiting the generality of the foregoing, Pledgor:

                                       5

<PAGE>

          (A)  will not enter into any agreement that would impair or conflict
     with Pledgor's obligations hereunder;

          (B)  will, from time to time, upon the Secured Party's request, cause
     its books and records to be marked with such legends or segregated in such
     manner as the Secured Party may specify and take or cause to be taken such
     other action and adopt such procedures as the Secured Party may specify to
     give notice or to perfect the security interest in the Pledged Collateral
     intended to be conveyed hereby; 

          (C)  will, promptly following its becoming aware thereof, notify the
     Secured Party of 

               (i)  any materially adverse determination in any proceeding in
          the United States Patent and Trademark Office or United States
          Copyright Office with respect to any Trademark or Copyright material
          to Pledgor's business; or 

               (ii) the institution of any proceeding or any materially adverse
          determination in any federal, state, local or foreign court or
          administrative bodies regarding Pledgor's claim of ownership in or
          right to use any of the Pledged Collateral, its right to register the
          Pledged Collateral, or its right to keep and maintain such
          registration in full force and effect;

          (D)  will properly maintain and protect the Pledged Collateral to the
     extent necessary or appropriate for the conduct of Pledgor's business (as
     presently conducted and as contemplated by the Loan Documents) and
     consistent with Pledgor's current practice,  in accordance with applicable
     statutory requirements;

          (E)  will not grant or permit to exist any Lien upon or with respect
     to the Pledged Collateral or any portion thereof except Liens in favor of
     the Secured Party for itself and the Secured Party or as permitted under
     this Agreement and Liens permitted by Section 7 hereof or with the express
     consent of the Secured Parties, and will not execute any security agreement
     or financing statement covering any of the Pledged Collateral except in the
     name of the Secured Party for itself and the Secured Party or as permitted
     under this Agreement; 

          (F)  except in accordance with prudent business practices, will not
     permit to lapse or become abandoned, settle or compromise any pending or
     future litigation or administrative proceeding with respect to the Pledged
     Collateral without the consent of the Secured Party, or contract for sale
     or otherwise dispose of the Pledged Collateral or any portion thereof
     except pursuant to Section 7 hereof;

          (G)  upon Pledgor obtaining knowledge thereof, will promptly notify
     the Secured Party in writing of any event which may reasonably be expected
     to materially affect the value or utility of the Pledged Collateral or any
     portion thereof, the ability of 

                                       6

<PAGE>

     Pledgor or the Secured Party to dispose of the Pledged Collateral or any 
     portion thereof or the rights and remedies of the Secured Party in 
     relation thereto including, without limitation, a levy or threat of levy 
     or any legal process against the Pledged Collateral or any portion 
     thereof;

          (H)  until the Secured Party exercises its rights to make collection,
     will diligently keep adequate records respecting the Pledged Collateral;

          (I)  subject to the first sentence of this Section 6(a), hereby
     authorizes the Secured Party, in its sole discretion, to file one or more
     financing or continuation statements and amendments thereto, relative to
     all or any part of the Pledged Collateral without the signature of Pledgor
     where permitted by law;

          (J)  will furnish to the Secured Party from time to time statements
     and amended schedules further identifying and describing the Pledged
     Collateral and such other materials evidencing or reports pertaining to the
     Pledged Collateral as the Secured Party may from time to time request, all
     in reasonable detail;

          (K)  will pay when due any and all taxes, levies, maintenance fees,
     charges, assessments, licenses fees and similar taxes or impositions
     payable in respect of the Pledged Collateral unless contesting in good
     faith pursuant to Section 5.4 of the Credit Agreement; and

          (L)  will comply in all material respects with all laws, rules and
     regulations applicable to the Pledged Collateral.

     (b)  If, before the Secured Obligations shall have been paid and satisfied
in full in cash or cash equivalents, Pledgor shall, (1) obtain any rights to any
additional Pledged Collateral as identified in SCHEDULE A hereto and as from
time to time amended, or (2) become entitled to the benefit of any additional
Pledged Collateral or any renewal or extension thereof, the provisions of this
Agreement shall automatically apply thereto and any item enumerated in clause
6(b)(1) or clause 6(b)(2) with respect to Pledgor shall automatically constitute
Pledged Collateral if such would have constituted Pledged Collateral at the time
of execution of this Agreement, and be subject to the assignment, Lien and
security interest created by this Agreement without further action by any party
to this agreement.  Pledgor shall promptly provide to the Secured Party written
notice of any of the foregoing.  Pledgor shall, at least once in each calendar
quarter, provide written notice to the Secured Party of all applications for
registration of Trademarks or Copyrights made during the preceding calendar
quarter.  Pledgor agrees, promptly following the written request by the Secured
Party, to confirm the attachment of the Lien and security interest created by
this Agreement to any rights described in clause 6(b)(1) or clause 6(b)(2) above
if such would have constituted Pledged Collateral at the time of execution of
this Agreement by execution of an instrument in form acceptable to the Secured
Party.

     (c)  Pledgor authorizes the Secured Party to modify this Agreement by
amending SCHEDULE A annexed hereto as appropriate to include any future Pledged
Collateral of Pledgor.  The provisions of this Agreement shall automatically
apply to any future Pledged Collateral.

     (d)  Pledgor shall commence and prosecute diligently in its own name, as
the real party in interest, for its own benefit, all applications for Trademarks
or Copyrights now or hereafter pending that would be useful or beneficial to the
business of Pledgor to which any such applications pertain, and to do all acts
necessary to preserve and maintain all rights in the Pledged Collateral unless
such Pledged Collateral has become obsolete to Pledgor's business, as reasonably
determined by Pledgor consistent with prudent business practices.  Pledger shall
bear any expenses incurred in connection with future applications for trademark
registrations.  Any and all costs and expenses incurred in connection with any
such actions shall be borne by Pledgor.  Except in accordance with prudent
business practices, Pledgor shall not abandon any right to file a Trademark or
Copyright application or any pending Trademark or Copyright application or any
Trademark or Copyright without the consent of the Secured Party. 

     Section 7.  TRANSFERS AND OTHER LIENS.  Pledgor will not (a) sell, convey,
assign or otherwise dispose of, or grant any option with respect to, any of the
Pledged Collateral except for licensing in the ordinary course of business and
such other transactions as may be permitted under the Credit Agreement or (b)
create or permit to exist any Lien upon or with respect to any of the Pledged
Collateral, except for Liens for taxes, assessments or government charges or
claims the payment of which is not at the time required and inchoate Liens
imposed by law (each of which shall, except to the extent otherwise required by
law, be subordinate to the lien created by this Agreement) and the lien granted
to the Secured Party under this Agreement.

     Section 8.  REMEDIES UPON DEFAULT.

     (a)  If any Event of Default shall have occurred and be continuing, the
Secured Party may to the full extent permitted by law, (1) exercise any and all
rights as beneficial and legal owner of the Pledged Collateral, including,
without limitation, perfecting assignment of any and all consensual rights and
powers with respect to the Pledged Collateral and (2) sell or assign or grant a
license to use, or cause to be sold or assigned or a license granted to use any
or all of the Pledged Collateral (in the case of Trademarks, along with the
goodwill associated therewith) or any part thereof, in each case, free of all
rights and claims of Pledgor therein and thereto.  In accordance with such
rights, the Secured Party shall have the (A) right to cause any or all of the
Pledged Collateral to be transferred of record into the name of the Secured
Party or its nominee and (B) the right to impose (i) such limitations and
restrictions on the sale or assignment of the Pledged Collateral as the Secured
Party may deem to be necessary or appropriate to comply with any law, rule or
regulation (federal, state or local) having applicability to the sale or
assignment, and (ii) any necessary or appropriate requirements for any required
governmental approvals or consents. 

     (b)  Except as provided in this Section 8 and other express notice
provisions of the Loan Documents, Pledgor hereby expressly waives, to the
fullest extent permitted by applicable 

                                       8

<PAGE>

law, any and all notices, advertisements, hearings or process of law in 
connection with the exercise by the Secured Party of any of their rights and 
remedies hereunder.

     (c)  Pledgor agrees that, to the extent notice of sale shall be required by
law, ten (10) days' written notice from the Secured Party of the time and place
of any public sale or of the time after which a private sale or other intended
disposition is to take place shall be commercially reasonable notification of
such matters.  In addition to the rights and remedies provided in this Agreement
and in the other Loan Documents, the Secured Party shall have all the rights and
remedies of a secured party under the UCC. 

     (d)  Any sale of, or the grant of options to purchase, or any other
realization upon, any Pledged Collateral shall operate to divest all right,
title, interest, claim and demand, either at law or in equity, of Pledgor
therein and thereto, and shall be a perpetual bar both at law and in equity
against Pledgor and against any and all Persons claiming or attempting to claim
the Pledged Collateral so sold, optioned or realized upon, or any part thereof,
from, through or under Pledgor. 

     Section 9.  APPLICATION OF PROCEEDS.  The proceeds of any Pledged
Collateral obtained pursuant to the exercise of any remedy set forth in Section
8 shall be applied, together with any other sums then held by the Secured Party
pursuant to this Agreement, promptly by the Secured Party: 

          FIRST, to the payment of all reasonable costs and expenses, fees,
     commissions and taxes of such sale, collection or other realization,
     including, without limitation, reasonable reimbursement to the Secured
     Party, the Secured Party and its agents and counsel for all expenses, fees,
     liabilities and advances made or incurred by them in connection therewith
     and all expenses, liabilities and advances made or incurred by the Secured
     Party in connection therewith, together with interest on each such amount
     at the highest rate then in effect under the Credit Agreement; 

          SECOND, to the payment of all other reasonable costs and expenses of
     such sale, collection or other realization, including, without limitation,
     reasonable reimbursement to the Secured Party and its agents and counsel
     for all expenses, fees, liabilities and advances made or incurred by them
     in connection therewith and all costs, liabilities and indebtedness made or
     incurred by the Secured Party in connection therewith together with
     interest on each such amount at the highest rate then in effect under the
     Credit Agreement; 

                                       9

<PAGE>

          THIRD, to the indefeasible payment in full in cash of the Secured
     Obligations, ratably according to the unpaid amounts thereof, without
     preference or priority of any kind among amounts so due and payable; and 

          FOURTH, to Pledgor, or its successors or assigns, or to whomsoever may
     be lawfully entitled to receive the same or as a court of competent
     jurisdiction may direct, of any surplus then remaining from such Proceeds.

          Section 10.  NO WAIVER; CUMULATIVE REMEDIES.  (a)  No failure on 
the part of the Secured Party to exercise, no course of dealing with respect 
to, and no delay on the part of the Secured Party in exercising, any right, 
power or remedy hereunder shall operate as a waiver thereof; nor shall any 
single or partial exercise of any such right, power or remedy hereunder 
preclude any other or further exercise thereof or the exercise of any other 
right, power or remedy. The remedies herein provided are cumulative and are 
not exclusive of any remedies provided by law. 

     (b)  In the event the Secured Party shall have instituted any proceeding to
enforce any right, power or remedy under this instrument by foreclosure, sale,
entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to the Secured
Party, then and in every such case, Pledgor and the Secured Party shall, to the
extent permitted by applicable law, be restored to their respective former
positions and rights hereunder with respect to the Pledged Collateral, and all
rights, remedies and powers of the Secured Party shall continue as if no such
proceeding had been instituted. 

     Section 11.  THE SECURED PARTY MAY PERFORM; THE SECURED PARTY APPOINTED
ATTORNEY-IN-FACT.  If Pledgor shall fail to do any act or thing that it has
covenanted to do hereunder or any warranty on the part of Pledgor contained
herein shall be breached, the Secured Party may (but shall not be obligated to)
do the same or cause it to be done or remedy any such breach, and may expend
funds for such purpose.  Any and all amounts so expended by the Secured Party
shall be paid by Pledgor promptly upon demand therefor, with interest at the
highest rate then in effect under the Credit Agreement during the period from
and including the date on which such funds were so expended to the date of
repayment.  Pledgor's obligations under this Section 11 shall survive the
termination of this Agreement and the discharge of Pledgor's other obligations
hereunder.  Pledgor hereby appoints the Secured Party, its attorney-in-fact with
an interest, with full authority in the place and stead of Pledgor and in the
name of Pledgor, or otherwise, from time to time in the Secured Party's
reasonable discretion to take any action and to execute any instruments
consistent with the terms of this Agreement and the other Loan Documents which
the Secured Party may deem necessary or advisable to accomplish the purposes of
this Agreement.  The foregoing grant of authority is a power of attorney coupled
with an interest and such appointment shall be irrevocable for the term of this
Agreement.  Pledgor hereby ratifies all that such attorney shall lawfully do or
cause to be done by virtue hereof. 

                                       10

     Section 12.  INDEMNITY.

     (a)  INDEMNITY.  Pledgor agrees to indemnify, reimburse and hold the
Secured Party and its successors, assigns, employees, agents and servants
(collectively, "Indemnities") harmless from and against any and all liabilities,
obligations, damages, injuries, penalties, claims, demands, actions, suits,
judgments and any and all reasonable costs and expenses (including, without
limitation, attorneys' fees and expenses and the allocated costs of internal
counsel) of what  ever kind and nature imposed on, asserted against or incurred
by any of the Indemnities in any way relating to or arising out of this
Agreement or in any other way connected with the administration of the
transactions contemplated hereby or the enforcement of any of the terms hereof,
or the preservation of any rights hereunder, or in any way relating to or
arising out of the manufacture, processing, ownership, ordering, purchase,
delivery, control, acceptance, lease, financing, possession, operation,
condition, sale, return or other disposition, or use of the Pledged Collateral
(including, without limitation, latent or other defects, whether or not
discoverable, any claim for trademark, trade secret or copyright infringement),
the violation of the laws of any country, state or other governmental body or
unit, any tort (including, without limitation, claims arising or imposed under
the doctrine of strict liability, or for or on account of injury to or the death
of any Person (including any Indemnitee)), or property damage, or contract
claim; provided that Pledgor shall have no obligation to an Indemnitee hereunder
to the extent it is finally judicially determined that such indemnified
liabilities arise solely from the gross negligence or willful misconduct of that
Indemnitee.  Upon written notice by any Indemnitee of the assertion of such a
liability, obligation, damage, injury, penalty, claim, demand, action, judgment
or suit, Pledgor shall assume full responsibility for the defense thereof.   If
any action, suit or proceeding arising from any of the foregoing is bought
against any Indemnitee, Pledgor shall, if requested by such Indemnitee, resist
and defend such action, suit or proceeding or cause the same to be resisted and
defended by counsel reasonably satisfactory to such Indemnitee.  Each Indemnitee
shall, unless any other Indemnitee has made the request described in the
preceding sentence and such request has been complied with, have the right to
employ its own counsel (or internal counsel) to investigate and control the
defense of any matter covered by the indemnity set forth in this Section 12 and
the reasonable fees and expenses of such counsel shall be paid by Pledgor;
provided that, only to the extent that no conflict exists between or among the
Indemnities as reasonably determined by the Indemnitee, Pledgor shall not be
obligated to pay the fees and expenses of more than one counsel for all
Indemnitees as a group with respect to any such matter, action, suit or
proceeding.

     (b)  MISREPRESENTATIONS.  Without limiting the application of subsection
12(a), Pledgor agrees to pay, indemnify and hold each Indemnitee harmless from
and against any loss, costs, damages and expenses which such Indemnitee may
suffer, expend or incur in consequence of or growing out of any material
misrepresentation by Pledgor in this Agreement or any of the other Loan
Documents or in any statement or writing contemplated by or made or delivered
pursuant to or in connection with this Agreement or any of the other Loan
Documents.

                                       11

<PAGE>

     (c)  CONTRIBUTION.  If and to the extent that the obligations of Pledgor
under this Section 12 are unenforceable for any reason, Pledgor hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations that is permissible under applicable law. 

     (d)  SURVIVAL.  The obligations of Pledgor contained in this Section 12
shall survive the termination of this Agreement and the discharge of Pledgor's
other obligations hereunder and under the other Loan Documents. 

     (e)  REIMBURSEMENT.  Any amounts paid by any Indemnitee as to which such
Indemnitee has the right to reimbursement shall constitute Secured Obligations
secured by the Pledged Collateral.

     Section 13.  LITIGATION.  (a) Pledgor shall have the right to commence and
diligently prosecute in its own name, as real party in interest, for its own
benefit and at its own expense, such applications for protection of Pledged
Collateral, suits, administrative proceedings or other actions for infringement,
counterfeiting, unfair competition, dilution or other damage as are in its
reasonable business judgment necessary to protect the Pledged Collateral. 
Pledgor shall promptly notify the Secured Party in writing as to the
commencement and prosecution of any such actions, or threat thereof relating to
the Pledged Collateral and shall provide to the Secured Party such information
with respect thereto as may be reasonably requested.  The Secured Party shall
provide all reasonable and necessary cooperation in connection with any such
suit, proceeding or action, including, without limitation, joining as a
necessary party.  

     (b)  Upon the occurrence and during the continuation of an Event of
Default, the Secured Party shall have the right but shall in no way be obligated
to file applications for protection of the Pledged Collateral and/or bring suit
in the name of Pledgor, the Secured Party or the Secured Party to enforce the
Pledged Collateral and any license thereunder; in the event of such suit,
Pledgor shall, at the request of the Secured Party, do any and all lawful acts
and execute any and all documents required by the Secured Party in aid of such
enforcement and Pledgor shall promptly, upon demand, reimburse and indemnify the
Secured Party, as the case may be, for all reasonable costs and expenses
incurred by the Secured Party in the exercise of its rights under this Section
13.  In the event that the Secured Party shall elect not to bring suit to
enforce the Pledged Collateral, Pledgor agrees to use all measures, whether by
action, suit, proceeding or otherwise, to prevent the infringement,
counterfeiting or other diminution in value of any of the Pledged Collateral by
others and for that purpose agrees to diligently maintain any action, suit or
proceeding against any person so infringing necessary to prevent such
infringement as is in the reasonable business judgment of Pledgor necessary to
protect the Pledged Collateral and the Secured Party shall provide, at Pledgor's
expense, all necessary and reasonable assistance to Pledgor to maintain such
action.

     Section 14.  MODIFICATIONS IN WRITING.  No amendment, modification,
supplement, termination or waiver of or to any provision of this Agreement, nor
consent to any departure by Pledgor therefrom, shall be effective unless the
same shall be in writing and signed by the Secured Party.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement, and any consent to any departure by Pledgor
from the terms of any provision of this Agreement, shall be effective only in
the specific instance and for the specific purpose for which made or given.

(other than Secured Obligations in the nature of continuing Indemnitee or 
expense reimbursement obligations not yet due and payable) have been paid in 
full and have been terminated and the Revolving Credit Loan Commitments of 
the Secured Party to make any Loan under the Credit Agreement have expired, 
this Agreement shall terminate.  Upon termination of this Agreement or any 
release of Pledged Collateral in accordance with the provisions of the Credit 
Agreement, the Secured Party shall, upon the request and at the expense of 
Pledgor, forthwith assign, transfer and deliver to Pledgor against receipt 
and without recourse to or warranty by the Secured Party, such of the Pledged 
Collateral to be released (in the case of a release) as may be in the 
possession of the Secured Party and as shall not have been sold or otherwise 
applied pursuant to the terms hereof, on the order of and at the expense of 
Pledgor, and proper instruments (including UCC termination statements on Form 
UCC-2 and documents suitable for recordation in the United States Patent and 
Trademark Office, the United States Copyright Office or similar domestic or 
foreign authority) acknowledging the termination of this Agreement or the 
release of such Pledged Collateral, as the case may be. 

     Section 16.  REINSTATEMENT.  Notwithstanding the provisions of Section 15,
this Agreement shall continue to be effective or be reinstated, as the case may
be, if at any time any amount received by the Secured Party in respect of the
Secured Obligations is rescinded or must otherwise be restored or returned by
the Secured Party upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of Pledgor or upon the appointment of any intervenor or
conservator of, or trustee or similar official for, Pledgor or any substantial
part of its properties, or otherwise, all as though such payments had not been
made.

     Section 17.  CREDIT AGREEMENT.  Notwithstanding any other provision of this
Agreement, the rights of the parties hereunder are subject to the provisions of
the Credit Agreement, including the provisions thereof pertaining to the rights
and responsibilities of the Secured Party.

     Section 19.  CONTINUING SECURITY INTEREST; ASSIGNMENT.  This Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(a) remain in full force and effect until the payment in full in cash of all
Secured Obligations, and release in accordance with section 15 of this Agreement
if in accordance with the provisions of the Credit Agreement, (b) be binding
upon Pledgor, its successors and assigns, and (c) inure, together with the
rights and remedies of the Secured Party hereunder, to the benefit of the
Secured Party and its successors, transferees and assigns; no other Persons
(including, without limitation, any other creditor of Pledgor) shall have any
interest herein or any right or benefit with respect hereto.  Without limiting
the generality of the foregoing clause 19(c), any the Secured Party may assign
or otherwise transfer any indebtedness held by it secured by this Agreement to
any other Person, and such other Person shall thereupon become vested with all
the benefits in respect thereof granted to the Secured Party, herein or
otherwise, subject however, to the provisions of the Credit Agreement.

AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE
COMMONWEALTH OF MASSACHUSETTS, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF

IRREVOCABLY AGREES IN WRITING TO SO SERVE AS PLEDGOR'S AGENT TO RECEIVE ON
PLEDGOR'S BEHALF, SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDINGS IN ANY SUCH
COURT, SUCH SERVICE IS HEREBY ACKNOWLEDGED BY PLEDGOR TO BE EFFECTIVE AND
BINDING SERVICE IN EVERY RESPECT.  A COPY OF SUCH PROCESS SO SERVED SHALL BE

HEREOF.  IF ANY AGENT APPOINTED BY PLEDGOR REFUSES TO ACCEPT SERVICE, PLEDGOR
HEREBY AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE. 
NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF THE SECURED PARTY TO BRING

                                  LANDLORD WAIVER

     The undersigned, ____________, under  ____________, dated ____________,,
recorded in  ____________, Registry of Deeds in Book ____________, Page
____________, ("the Landlord"), with a principal office ____________, is the
Landlord under the certain lease, dated  ____________, as amended  ____________,
which, expires  ____________,(the "Lease") with  ____________,(the "Borrower")
covering certain property (the "Leased Premises") located at  ____________, and
more fully described in the Lease.  The Landlord represents that the Lease in
the form attached hereto as EXHIBIT A, is in full force and effect and has not
been assigned, modified, supplemented or amended in any way, [except], that no
lien exists on the property, and that it is unaware of any current condition
constituting a default under the Lease or which would permit Landlord to
terminate the Lease.

     It is understood and acknowledged that BANKBOSTON, N.A. (the "Bank") has
entered into an Revolving Credit and Term Loan Agreement (the  ____________
"Credit Agreement") and related documents and instruments (collectively, the
"Loan Documents") with the Borrower, secured, INTER ALIA, by all of the
Borrower's tangible and intangible personal property, now owned or hereafter
acquired, as set forth on Schedule A hereto (collectively, the "Collateral").

     For valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Landlord does hereby waive any and all rights in the
Collateral which the Landlord may have under statute, case law or by contract
and hereby agrees that the Collateral shall remain personal property of the
Borrower at all times, notwithstanding that the Collateral, or any part thereof,
may now be or hereafter become in any manner affixed or attached to, or embedded
in, or permanently resting on, real property or any building thereon, or
attached in any manner to that which is permanent by any means.

     The Landlord at all times during the term of the Lease shall permit the
Bank and its agents and representatives to come on to the Leased Premises to
dispose of, remove or conduct the sale of the Collateral, and further agrees
that if the Landlord shall commence any action to gain possession of the Leased
Premises or to terminate the Lease, that it shall notify the Bank of such action
and shall permit the Bank and its agents and representatives to come on the
Leased Premises after the Landlord has regained possession of the Leased
Premises to dispose of, remove or conduct the sale of the Collateral for up to
sixty (60) days upon payment of the basic rent due under the Lease (as in effect
immediately prior to such repossession by the Landlord) on a per diem basis for
the number of days the Bank is in possession, unless the Borrower has already
paid for such period.  The Bank shall use due care during any such period in
which it is on the Leased Premises and shall, in a workman like manner, repair
any damage caused to the Leased Premises by the Bank's removal of the Collateral
from the Leased Premises.

     The Landlord further agrees that it will notify the Bank if the Borrower
defaults on its obligations under the Lease and allow the Bank ten (10) days
from the Bank's receipt of such 

<PAGE>

notice to cure or cause the Borrower to cure any payment default and thirty 
(30) days from its receipt of notice to cure or cause the Borrower to cure 
any other such defaults.

     Without limiting the foregoing, nothing contained herein shall limit or
modify the current or future obligations of any nature due from the Borrower to
the Lender.

     IN WITNESS WHEREOF, the Landlord has executed these presents this __ day of
_____________, 1998.

Ladies and Gentlemen:

     As required by Section 5.1(d) of the Revolving Credit and Term Loan
Agreement dated as of May   , 1998 (the "Credit Agreement") among Rubio's
Restaurants, Inc and Rubio's Restaurants of Nevada, Inc. and BankBoston, N.A., a
review of the activities of the Borrower for the fiscal year and/or fiscal
quarter and/or calendar month ending ___________, _____ (the "FISCAL PERIOD")
has been made under my supervision to determine whether the Borrower has
performed and/or maintained all of its obligations under the Credit Agreement. 
Based upon such review, I hereby certify to you, as a Senior Officer, that the
Borrower has performed and maintained all such Obligations under the Credit
Agreement for the Fiscal Period and, to the best of my knowledge, no event has
occurred that constitutes a Default or an Event of Default as defined in the
Credit Agreement.

     As required by Section [5.1(a)][5.1(b)][5.1 (c)] of the Credit Agreement,
financial statements of the Company (the "FINANCIAL STATEMENTS") for the Fiscal
Period and other information required by such sections accompany this
certificate.  The Financial Statements present fairly the financial position of
the Credit Parties as of the date thereof and the statements of operation of the
Credit Parties for the Fiscal Period covered thereby.  No change in GAAP or in
the application thereof has occurred since the date of the financial statements
delivered pursuant to Section 3.4 (a)(ii) of the Credit Agreement.

     I further certify to you, as a Senior Officer, that the figures set forth

                          RUBIO'S RESTAURANTS, INC.

                     RESTRICTED STOCK ISSUANCE AGREEMENT


              AGREEMENT made as of this ____ day of _____________, 199__, by
and among Rubio's Restaurants, Inc., a California corporation (the
"Corporation"), ____________________________, a participant ("Participant") in
the Corporation's 1995 Stock Option/Stock Issuance Plan (the "Plan") and
____________________________, the Participant's spouse.

     I.       PURCHASE OF SHARES

              1.1    PURCHASE.  The Participant hereby purchases, and the
Corporation hereby sells to Participant, __________ shares (the "Shares") of the
Corporation's common stock ("Common Stock") at a purchase price of $_________
per share (the "Purchase Price") pursuant to the provisions of the Plan.  

              1.2    PAYMENT.  Concurrently with the execution of this
Agreement, the Participant shall deliver to the Corporate Secretary of the
Corporation (i) the aggregate Purchase Price payable for the Shares in cash or
cash equivalent and (ii) a duly-executed blank Assignment Separate from
Certificate (in the form attached hereto as Exhibit A). 

              1.3    DELIVERY OF CERTIFICATES.  The certificates representing
the Shares hereunder shall be held in escrow by the Secretary of the Corporation
as provided in Article VII hereof.

              1.4    SHAREHOLDER RIGHTS.  Until such time as the Corporation
actually exercises its repurchase right, rights of first refusal or special
purchase right under this Agreement, Participant (or any successor in interest)
shall have all the rights of a shareholder (including voting and dividend
rights) with respect to the Shares, including the Shares held in escrow under
Article VII, subject, however, to the transfer restrictions of Article IV.

    II.       SECURITIES LAW COMPLIANCE

              2.1    EXEMPTION FROM REGISTRATION.  The Shares have not been
registered under the Securities Act of 1933, as amended (the "1933 Act"), and
are accordingly being issued to Participant in reliance upon the exemption from
such registration provided by Rule 701 of the Securities and Exchange Commission
for stock issuances under compensatory benefit plans such as the Plan. 
Participant hereby acknowledges receipt of a copy of the documentation for such
Plan in the form of Exhibit B attached hereto. 


<PAGE>

              2.2    RESTRICTED SECURITIES.  

                     A.     Participant hereby confirms that Participant has
been informed that the Shares are restricted securities under the 1933 Act and
may not be resold or transferred unless the Shares are first registered under
the Federal securities laws or unless an exemption from such registration is
available.  Accordingly, Participant hereby acknowledges that Participant is
prepared to hold the Shares for an indefinite period and that Participant is
aware that Rule 144 of the Securities and Exchange Commission issued under the
1933 Act is not presently available to exempt the sale of the Shares from the
registration requirements of the 1933 Act.  

                     B.     Upon the expiration of the ninety (90)-day period
immediately following the date on which the Corporation first becomes subject to
the reporting requirements of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), the Shares, to the extent vested under Article V, may be
sold (without registration) pursuant to the applicable requirements of Rule 144.
If Participant is at the time of such sale an affiliate of the Corporation for
purposes of Rule 144 or was such an affiliate during the preceding three (3)
months, then the sale must comply with all the requirements of Rule 144
(including the volume limitation on the number of shares sold, the
broker/market-maker sale requirement and the requisite notice to the Securities
and Exchange Commission); however, the two-year holding period requirement of
the Rule will not be applicable.  If Participant is not at the time of the sale
an affiliate of the Corporation nor was such an affiliate during the preceding
three (3) months, then none of the requirements of Rule 144 (other than the
broker/market-maker sale requirement for Shares held for less than three (3)
years following payment in cash of the Purchase Price therefor) will be
applicable to the sale.

                     C.     Should the Corporation not become subject to the
reporting requirements of the Exchange Act, then Participant may, provided
he/she is not at the time an affiliate of the Corporation (nor was such an
affiliate during the preceding three (3) months), sell the Shares (without
registration) pursuant to paragraph (k) of Rule 144 after the Shares have been
held for a period of three (3) years following the payment in cash of the
Purchase Price for such shares.


              2.3    DISPOSITION OF SHARES.  Participant hereby agrees that
Participant shall make no disposition of the Shares (other than a permitted
transfer under paragraph 4.1) unless and until there is compliance with all of
the following requirements:


                                     -2-

<PAGE>

              (a)    Participant shall have notified the Corporation of the
       proposed disposition and provided a written summary of the terms and
       conditions of the proposed disposition.

              (b)    Participant shall have complied with all requirements of
       this Agreement applicable to the disposition of the Shares.

              (c)    Participant shall have provided the Corporation with
       written assurances, in form and substance satisfactory to the
       Corporation, that (i) the proposed disposition does not require
       registration of the Shares under the 1933 Act or (ii) all appropriate
       action necessary for compliance with the registration requirements of the
       1933 Act or of any exemption from registration available under the 1933
       Act (including Rule 144) has been taken.

              (d)    Participant shall have provided the Corporation with
       written assurances, in form and substance satisfactory to the
       Corporation, that the proposed disposition will not result in the
       contravention of any transfer restrictions applicable to the Shares
       pursuant to the provisions of the Commissioner Rules identified in
       paragraph 2.5.

              The Corporation shall NOT be required (i) to transfer on its books
any Shares which have been sold or transferred in violation of the provisions of
this Article II NOR (ii) to treat as the owner of the Shares, or otherwise to
accord voting or dividend rights to, any transferee to whom the Shares have been
transferred in contravention of this Agreement.

              2.4    RESTRICTIVE LEGENDS.  In order to reflect the restrictions
on disposition of the Shares, the stock certificates for the Shares will be
endorsed with restrictive legends, including one or more of the following
legends:

                   (i)      "The shares represented by this certificate have not
       been registered under the Securities Act of 1933.  The shares may not be
       sold or offered for sale in the absence of (a) an effective registration
       statement for the shares under such Act, (b) a 'no action' letter of the
       Securities and Exchange Commission with respect to such sale or offer, or
       (c) satisfactory assurances to the Corporation that registration under
       such Act is not required with respect to such sale or offer."


                                     -3-

<PAGE>

                  (ii)      "It is unlawful to consummate a sale or transfer of
       this security, or any interest therein, or to receive any consideration
       therefor, without the prior written consent of the Commissioner of
       Corporations of the State of California, except as permitted in the
       Commissioner's Rules."

                 (iii)      "The shares represented by this certificate are
       unvested and accordingly may not be sold, assigned, transferred,
       encumbered, or in any manner disposed of except in conformity with the
       terms of a written agreement dated ____________, 19__, between the
       Corporation and the registered holder of the shares (or the predecessor
       in interest to the shares).  Such agreement grants certain repurchase
       rights and rights of first refusal to the Corporation (or its assignees)
       upon the sale, assignment, transfer, encumbrance or other disposition of
       the Corporation's shares or upon termination of service with the
       Corporation.  The Corporation will upon written request furnish a copy of
       such agreement to the holder hereof without charge."

              2.5    RECEIPT OF COMMISSIONER RULES.  Participant hereby
acknowledges receipt of a copy of Section 260.141.11 of the Rules of the
California Corporations Commissioner, a copy of which is attached as Exhibit C
to this Agreement.

   III.       SPECIAL TAX PROVISIONS

              3.1    SECTION 83(B) ELECTION.  The Participant understands that
under Section 83 of the Code, the excess of the fair market value of the Shares
on the date any forfeiture restrictions applicable to such shares lapse over the
Purchase Price for such Shares will be reportable as ordinary income on such
lapse date.  For this purpose, the term "forfeiture restrictions" includes the
right of the Corporation to repurchase the Shares pursuant to the Repurchase
Right provided under Article V of this Agreement.  Participant understands that
he/she may elect under Section 83(b) of the Internal Revenue Code of 1986, as
amended (the "Code") to be taxed at the time the Shares are acquired hereunder,
rather than when and as such Shares cease to be subject to such forfeiture
restrictions.  Such election must be filed with the Internal Revenue Service
within thirty (30) days after the date of this Agreement.  Even if the fair
market value of the Shares on the date of this Agreement equals the Purchase
Price paid (and thus no tax is payable), the election must be made to avoid
adverse tax consequences in the future.  The form for making this election is
attached as Exhibit D hereto.  Participant understands that failure to make this
filing within the thirty (30)-day period will result in the 


                                     -4-

<PAGE>

recognition of ordinary income by the Participant as the forfeiture 
restrictions lapse.

              3.2    PARTICIPANT ACKNOWLEDGES THAT IT IS PARTICIPANT'S SOLE
RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER
SECTION 83(b), EVEN IF PARTICIPANT REQUESTS THE CORPORATION OR ITS
REPRESENTATIVES TO MAKE THIS FILING ON HIS/HER BEHALF.  This filing should be
made by registered or certified mail, return receipt requested, and Participant
must retain two (2) copies of the completed form for filing with his/her State
and Federal tax returns for the current tax year and an additional copy for
his/her personal records.

    IV.       TRANSFER RESTRICTIONS

              4.1    RESTRICTION ON TRANSFER.  Participant shall not 
transfer, assign, encumber or otherwise dispose of any of the Shares which 
are subject to the Corporation's Repurchase Right under Article V.  In 
addition, Shares which are released from the Repurchase Right shall not be 
transferred, assigned, encumbered or otherwise made the subject of 
disposition in contravention of the Corporation's First Refusal Right under 
Article VI.  Such restrictions on transfer, however, shall NOT be applicable 
to (i) a gratuitous transfer of the Shares made to the Participant's spouse 
or issue, including adopted children, or to a trust for the exclusive benefit 
of the Participant or the Participant's spouse or issue, PROVIDED AND ONLY IF 
the Participant obtains the Corporation's prior written consent to such 
transfer, (ii) a transfer of title to the Shares effected pursuant to the 
Participant's will or the laws of intestate succession or (iii) a transfer to 
the Corporation in pledge as security for any purchase-money indebtedness 
incurred by the Participant in connection with the acquisition of the Shares.

              4.2    TRANSFEREE OBLIGATIONS.  Each person (other than the 
Corporation) to whom the Shares are transferred by means of one of the 
permitted transfers specified in paragraph 4.1 must, as a condition precedent 
to the validity of such transfer, acknowledge in writing to the Corporation 
that such person is bound by the provisions of this Agreement and that the 
transferred shares are subject to (i) both the Corporation's Repurchase Right 
and the Corporation's First Refusal Right granted hereunder and (ii) the 
market stand-off provisions of paragraph 4.4, to the same extent such Shares 
would be so subject if retained by the Participant.

              4.3    DEFINITION OF OWNER.  For purposes of Articles IV, V, VI
and VII of this Agreement, the term "Owner" shall include the Participant and
all subsequent holders of the Shares who derive their chain of ownership through
a permitted transfer from the Participant in accordance with paragraph 4.1.

              4.4    MARKET STAND-OFF PROVISIONS.

              A.     In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Shares without the prior written consent of the Corporation or
its underwriters.  Such limitations shall be in effect for such period of time
from and after the effective date of such registration statement as may be
requested by the Corporation or such underwriters; PROVIDED, however, that in no
event shall such period exceed one hundred-eighty (180) days.  The limitations
of this paragraph 4.4 shall remain in effect for the two-year period immediately
following the effective date of the Corporation's initial public offering and
shall thereafter terminate and cease to have any force or effect.

              B.     Owner shall be subject to the market stand-off provisions
of this paragraph 4.4 PROVIDED AND ONLY IF the officers and directors of the
Corporation are also subject to similar arrangements.

              C.     In the event of any stock dividend, stock split,
recapitalization or other change affecting the Corporation's outstanding Common
Stock effected without receipt of consideration, then any new, substituted or
additional securities distributed with respect to the Shares shall be
immediately subject to the provisions of this paragraph 4.4, to the same extent
the Shares are at such time covered by such provisions.

              D.     In order to enforce the limitations of this paragraph 4.4,
the Corporation may impose stop-transfer instructions with respect to the Shares
until the end of the applicable stand-off period.

     V.       REPURCHASE RIGHT

              5.1    GRANT.  The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date the Participant ceases for any reason to remain in Service or
(if later) during the sixty (60)-day period following the execution date of this
Agreement, to repurchase at the Purchase Price all or (at the discretion of the
Corporation and with the consent of the Participant) any portion of the Shares
in which the Participant has not acquired a vested interest in accordance with
the vesting provisions of paragraph 5.3 below (such shares to be hereinafter

called the "Unvested Shares").  For purposes of this Agreement, the Participant
shall be deemed to remain in Service for so long as the Participant continues to
render periodic services to the Corporation or any parent or subsidiary
corporation, whether as an employee, a non-employee member of the board of
directors, or an independent contractor or consultant.

              5.2    EXERCISE OF THE REPURCHASE RIGHT.  The Repurchase Right
shall be exercisable by written notice delivered to the Owner of the Unvested
Shares prior to the expiration of the applicable sixty (60)-day period specified
in paragraph 5.1.  The notice shall indicate the number of Unvested Shares to be
repurchased and the date on which the repurchase is to be effected, such date to
be not more than thirty (30) days after the date of notice.  To the extent one
or more certificates representing Unvested Shares may have been previously
delivered out of escrow to the Owner, then Owner shall, prior to the close of
business on the date specified for the repurchase, deliver to the Secretary of
the Corporation the certificates representing the Unvested Shares to be
repurchased, each certificate to be properly endorsed for transfer.  The
Corporation shall, concurrently with the receipt of such stock certificates
(either from escrow in accordance with paragraph 7.3 or from Owner as herein
provided), pay to Owner in cash or cash equivalents (including the cancellation
of any purchase-money indebtedness), an amount equal to the Purchase Price
previously paid for the Unvested Shares which are to be repurchased.

              5.3    TERMINATION OF THE REPURCHASE RIGHT.  The Repurchase Right
shall terminate with respect to any Unvested Shares for which it is not timely
exercised under paragraph 5.2.  In addition, the Repurchase Right shall
terminate, and cease to be exercisable, with respect to any and all Shares in
which the Participant vests in accordance with the schedule below.  Accordingly,
as the Participant continues in Service, the Participant shall acquire a vested
interest in, and the Repurchase Right shall lapse with respect to, the Shares in
installments in accordance with the following provisions:

                   (i)      The Participant shall not acquire any vested 
       interest in, nor shall the Repurchase Right lapse with respect to, any 
       Shares unless and until the Participant has completed twelve (12) 
       months of Service measured from _________________, 199__.

                  (ii)      Upon the completion of the twelve (12) month 
       Service period specified in subparagraph (i) above, the Participant 
       shall acquire a vested interest in, and the Repurchase Right shall 
       lapse with respect to, 25% of the Shares. 


                                     -7-

<PAGE>

                 (iii)      The Participant shall acquire a vested interest 
        in, and the Repurchase Right shall lapse with respect to, the 
        remaining Shares in a series of successive equal monthly installments 
        over each of the next thirty-six (36) months of Service completed by 
        the Participant after the initial vesting date under subparagraph 
        (ii) above.

              All Shares as to which the Repurchase Right lapses shall, 
however, continue to be subject to (i) the First Refusal Right and (ii) the 
market stand-off provisions of paragraph 4.4.

              5.4    FRACTIONAL SHARES.  No fractional shares shall be
repurchased by the Corporation.  Accordingly should the Repurchase Right extend
to a fractional share (in accordance with the vesting computation provisions of
paragraph 5.3) at the time the Participant ceases Service, then such fractional
share shall be added to any fractional share in which the Participant is at such
time vested in order to make one whole vested share no longer subject to the
Repurchase Right.

              5.5    ADDITIONAL SHARES OR SUBSTITUTED SECURITIES.  In the event
of any stock dividend, stock split, recapitalization or other change affecting
the Corporation's outstanding Common Stock as a class effected without receipt
of consideration, then any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which is
by reason of any such transaction distributed with respect to the Shares shall
be immediately subject to the Repurchase Right, but only to the extent the
Shares are at the time covered by such right.  Appropriate adjustments to
reflect the distribution of such securities or property shall be made to the
number of Shares at the time subject to the Repurchase Right hereunder and to
the price per share to be paid upon the exercise of the Repurchase Right in
order to reflect the effect of any such transaction upon the Corporation's
capital structure; PROVIDED, however, that the aggregate Purchase Price shall
remain the same.

              5.6    CORPORATE TRANSACTION.

              A.     Immediately prior to the consummation of any of the
following shareholder-approved transactions (a "Corporate Transaction"):

                   (i)      a merger or consolidation in which more than fifty 
        percent (50%) of the Corporation's outstanding voting stock is 
        transferred to a person or persons different from those who held the 
        stock immediately prior to such transaction, or 


                                     -8-

<PAGE>

                  (ii)      the sale, transfer or other disposition of all or
       substantially all of the Corporation's assets in complete liquidation or
       dissolution of the Corporation, 

                        the Repurchase Right shall automatically lapse in its
entirety, except to the extent the Repurchase Right is to be assigned to the
successor corporation (or its parent company) in connection with such Corporate
Transaction.

              B.     To the extent the Repurchase Right remains in effect
following such Corporate Transaction, it shall apply to the new capital stock or
other property (including cash) received in exchange for the Shares in
consummation of the Corporate Transaction, but only to the extent the Shares are
at the time covered by such right.  Appropriate adjustments shall be made to the
price per share payable upon exercise of the Repurchase Right to reflect the
effect of the Corporate Transaction upon the Corporation's capital structure;
PROVIDED, however, that the aggregate Purchase Price shall remain the same.

    VI.       RIGHT OF FIRST REFUSAL

              6.1    GRANT.  The Corporation is hereby granted the right of
first refusal (the "First Refusal Right"), exercisable in connection with any
proposed transfer of the Shares in which the Participant has vested in
accordance with the vesting provisions of Article V.  For purposes of this
Article VI, the term "transfer" shall include any sale, assignment, pledge,
encumbrance or other disposition for value of the Shares intended to be made by
the Owner, but shall not include any of the permitted transfers under paragraph
4.1.

              6.2    NOTICE OF INTENDED DISPOSITION.  In the event the Owner
desires to accept a bona fide third-party offer for any or all of the Shares
(the shares subject to such offer to be hereinafter called the "Target Shares"),
Owner shall promptly (i) deliver to the Corporate Secretary of the Corporation
written notice (the "Disposition Notice") of the terms and conditions of the
offer, including the purchase price and the identity of the third-party offeror
and (ii) provide satisfactory proof that the disposition of the Target Shares to
such third-party offeror would not be in contravention of the provisions set
forth in Articles II and IV of this Agreement.

              6.3    EXERCISE OF RIGHT.  The Corporation (or its assignees)
shall, for a period of twenty-five (25) days following receipt of the
Disposition Notice, have the right to repurchase any or all of the Target Shares
specified in the Disposition Notice upon substantially the same terms and
conditions specified therein or upon terms and conditions which do not
materially vary 


                                     -9-

<PAGE>

from those specified therein.  Such right shall be exercisable by delivery of 
written notice (the "Exercise Notice") to Owner prior to the expiration of 
the twenty-five (25)-day exercise period.  If such right is exercised with 
respect to all the Target Shares specified in the Disposition Notice, then 
the Corporation (or its assignees) shall effect the repurchase of the Target 
Shares, including payment of the purchase price, not more than five (5) 
business days after delivery of the Exercise Notice; and at such time Owner 
shall deliver to the Corporation the certificates representing the Target 
Shares to be repurchased, each certificate to be properly endorsed for 
transfer.  To the extent any of the Target Shares are at the time held in 
escrow under Article VII, the certificates for such shares shall 
automatically be released from escrow and delivered to the Corporation for 
purchase.

              6.4    NON-EXERCISE OF RIGHT.  In the event the Exercise Notice is
not given to Owner within twenty-five (25) days following the date of the
Corporation's receipt of the Disposition Notice, Owner shall have a period of
thirty (30) days thereafter in which to sell or otherwise dispose of the Target
Shares to the third-party offeror identified in the Disposition Notice upon
terms and conditions (including the purchase price) no more favorable to such
third-party offeror than those specified in the Disposition Notice; PROVIDED,
however, that any such sale or disposition must not be effected in contravention
of the provisions of Article II of this Agreement.  To the extent any of the
Target Shares are at the time held in escrow under Article VII, the certificates
for such shares shall automatically be released from escrow and surrendered to
the Owner.  The third-party offeror shall acquire the Target Shares free and
clear of the Corporation's Repurchase Right under Article V and the
Corporation's First Refusal Right hereunder, but the acquired shares shall
remain subject to (i) the securities law restrictions of paragraph 2.2(a) and
(ii) the market stand-off provisions of paragraph 4.4.  In the event Owner does
not effect such sale or disposition of the Target Shares within the specified
thirty (30) day period, the Corporation's First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses in accordance with paragraph 6.7.

              6.5    PARTIAL EXERCISE OF RIGHT.  In the event the Corporation
(or its assignees) makes a timely exercise of the First Refusal Right with
respect to a portion, but not all, of the Target Shares specified in the
Disposition Notice, Owner shall have the option, exercisable by written notice
to the Corporation delivered within thirty (30) days after the date of the
Disposition Notice, to effect the sale of the Target Shares pursuant to one of
the following alternatives:


                                    -10-

<PAGE>

                   (i)      sale or other disposition of all the Target Shares 
        to the third-party offeror identified in the Disposition Notice, but 
        in full compliance with the requirements of paragraph 6.4, as if the 
        Corporation did not exercise the First Refusal Right hereunder; or

                  (ii)      sale to the Corporation (or its assignees) of the 
        portion of the Target Shares which the Corporation (or its assignees) 
        has elected to purchase, such sale to be effected in substantial 
        conformity with the provisions of paragraph 6.3.

              Failure of Owner to deliver timely notification to the Corporation
under this paragraph 6.5 shall be deemed to be an election by Owner to sell the
Target Shares pursuant to alternative (i) above.

              6.6    RECAPITALIZATION/MERGER.

              (a)    In the event of any stock dividend, stock split,
recapitalization or other transaction affecting the Corporation's outstanding
Common Stock as a class effected without receipt of consideration, then any new,
substituted or additional securities or other property which is by reason of
such transaction distributed with respect to the Purchased Shares shall be
immediately subject to the Corporation's First Refusal Right hereunder, but only
to the extent the Purchased Shares are at the time covered by such right.

              (b)    In the event of any of the following transactions:

                          (i)      a merger or consolidation in which the
       Corporation is not the surviving entity, 

                         (ii)      a sale, transfer or other disposition of all
       or substantially all of the Corporation's assets, 

                        (iii)      a reverse merger in which the Corporation is
       the surviving entity but in which the Corporation's outstanding voting
       securities are transferred in whole or in part to person or persons other
       than those who held such securities immediately prior to the merger, or

                         (iv)      any transaction effected primarily to change
       the State in which the Corporation is incorporated, or to create a
       holding company structure, 


                                    -11-


<PAGE>

                     the Corporation's First Refusal Right shall remain in full
force and effect and shall apply to the new capital stock or other property
received in exchange for the Purchased Shares in consummation of the transaction
but only to the extent the Purchased Shares are at the time covered by such
right.

              6.7    LAPSE.  The First Refusal Right under this Article VI shall
lapse and cease to have effect upon the EARLIEST to occur of (i) the first date
on which shares of the Corporation's Common Stock are held of record by more
than five hundred (500) persons, (ii) a determination is made by the
Corporation's Board of Directors that a public market exists for the outstanding
shares of the Corporation's Common Stock, or (iii) a firm commitment
underwritten public offering pursuant to an effective registration statement
under the 1933 Act, covering the offer and sale of the Corporation's Common
Stock in the aggregate amount of at least $5,000,000.  However, the market
stand-off provisions of paragraph 4.4 shall continue to remain in full force and
effect following the lapse of the First Refusal Right hereunder.

   VII.       ESCROW

              7.1    DEPOSIT.  Upon issuance, the certificates for any Unvested
Shares purchased hereunder shall be deposited in escrow with the Corporation to
be held in accordance with the provisions of this Article VII.  Each deposited
certificate shall be accompanied by a duly executed Assignment Separate from
Certificate in the form of Exhibit A.  The deposited certificates, together with
any other assets or securities from time to time deposited with the Corporation
pursuant to the requirements of this Agreement, shall remain in escrow until
such time or times as the certificates (or other assets and securities) are to
be released or otherwise surrendered for cancellation in accordance with
paragraph 7.3.  Upon delivery of the certificates (or other assets and
securities) to the Corporation, the Owner shall be issued an instrument of
deposit acknowledging the number of Unvested Shares (or other assets and
securities) delivered in escrow to the Corporation.

              7.2    RECAPITALIZATION.  All regular cash dividends on the
Unvested Shares (or other securities at the time held in escrow) shall be paid
directly to the Owner and shall not be held in escrow.  However, in the event of
any stock dividend, stock split, recapitalization or other change affecting the
Corporation's outstanding Common Stock as a class effected without receipt of
consideration or in the event of a Corporate Transaction, any new, substituted
or additional securities or other property which is by reason of such
transaction distributed with respect to the Unvested Shares shall be immediately
delivered to the Corporation to be held in escrow under this 


                                    -12-

<PAGE>

Article VII, but only to the extent the Unvested Shares are at the time subject 
to the escrow requirements of paragraph 7.1.

              7.3    RELEASE/SURRENDER.  The Unvested Shares, together with any
other assets or securities held in escrow hereunder, shall be subject to the
following terms and conditions relating to their release from escrow or their
surrender to the Corporation for repurchase and cancellation:

                   (i)      Should the Corporation (or its assignees) elect to
       exercise the Repurchase Right under Article V with respect to any
       Unvested Shares, then the escrowed certificates for such Unvested Shares
       (together with any other assets or securities issued with respect
       thereto) shall be delivered to the Corporation, concurrently with the
       payment to the Owner, in cash or cash equivalent (including the
       cancellation of any purchase-money indebtedness), of an amount equal to
       the aggregate Purchase Price for such Unvested Shares, and the Owner
       shall cease to have any further rights or claims with respect to such
       Unvested Shares (or other assets or securities attributable to such
       Unvested Shares).

                  (ii)      Should the Corporation (or its assignees) elect to
       exercise its First Refusal Right under Article VI with respect to any
       vested Target Shares held at the time in escrow hereunder, then the
       escrowed certificates for such Target Shares (together with any other
       assets or securities attributable thereto) shall, concurrently with the
       payment of the paragraph 6.3 purchase price for such Target Shares to the
       Owner, be surrendered to the Corporation, and the Owner shall cease to
       have any further rights or claims with respect to such Target Shares (or
       other assets or securities).

                 (iii)      Should the Corporation (or its assignees) elect NOT
       to exercise its First Refusal Right under Article VI with respect to any
       Target Shares held at the time in escrow hereunder, then the escrowed
       certificates for such Target Shares (together with any other assets or
       securities attributable thereto) shall be surrendered to the Owner for
       disposition in accordance with the provisions of paragraph 6.4.

                  (iv)      As the interest of the Participant in the Unvested
       Shares (or any other assets or securities attributable thereto) vests in
       accordance with the provisions of Article V, the certificates for such


                                    -13-

<PAGE>

       vested shares (as well as all other vested assets and securities) shall
       be released from escrow and delivered to the Owner in accordance with the
       following schedule:

                     a.     The initial release of vested shares (or
              other vested assets and securities) from escrow shall be
              effected within thirty (30) days following the expiration
              of the initial twelve (12)-month period measured from the
              initial vesting date under paragraph 5.3.

                     b.     Subsequent releases of vested shares (or
              other vested assets and securities) from escrow shall be
              effected at semi-annual intervals thereafter, with the
              first such semi-annual release to occur six (6) months
              after the initial paragraph 5.3 vesting date.

                     c.     Upon the Participant's cessation of Service,
              any escrowed Shares (or other assets or securities) in
              which the Participant is at the time vested shall be
              promptly released from escrow.

                     d.     Upon any earlier termination of the
              Corporation's Repurchase Right in accordance with the
              applicable provisions of Article V, the Shares (or other
              assets or securities) at the time held in escrow hereunder
              shall promptly be released to the Owner as fully-vested
              shares or other property.

                   (v)      All Shares (or other assets or securities) released
       from escrow in accordance with the provisions of subparagraph (iv) above
       shall nevertheless remain subject to (I) the Corporation's First Refusal
       Right under Article VI until such right lapses pursuant to paragraph 6.7,
       (II) the market stand-off provisions of paragraph 4.4 until such
       provisions terminate in accordance therewith and (III) the Special
       Purchase Right under Article VIII.

  VIII.       MARITAL DISSOLUTION OR LEGAL SEPARATION

              8.1    GRANT.  In connection with the dissolution of the
Participant's marriage or the legal separation of the Participant and the
Participant's spouse, the Corporation shall have the right (the "Special
Purchase Right"), exercisable at any time 


                                    -14-

<PAGE>

during the thirty (30)-day period following the Corporation's receipt of the 
required Dissolution Notice under paragraph 8.2, to purchase from the 
Participant's spouse, in accordance with the provisions of paragraph 8.3, all 
or any portion of the Shares which would otherwise be awarded to such spouse 
in settlement of any community property or other marital property rights such 
spouse may have in such shares.

              8.2    NOTICE OF DECREE OR AGREEMENT.  The Participant shall
promptly provide the Secretary of the Corporation with written notice (the
"Dissolution Notice") of (i) the entry of any judicial decree or order resolving
the property rights of the Participant and the Participant's spouse in
connection with their marital dissolution or legal separation or (ii) the
execution of any contract or agreement relating to the distribution or division
of such property rights.  The Dissolution Notice shall be accompanied by a copy
of the actual decree of dissolution or settlement agreement between the
Participant and the Participant's spouse which provides for the award to the
spouse of one or more Shares in settlement of any community property or other
marital property rights such spouse may have in such shares.

              8.3    EXERCISE OF SPECIAL PURCHASE RIGHT.  The Special Purchase
Right shall be exercisable by delivery of the Purchase Notice to the Participant
and the Participant's spouse within thirty (30) days after the Corporation's
receipt of the Dissolution Notice.  The Purchase Notice shall indicate the
number of shares to be purchased by the Corporation, the date such purchase is
to be effected (such date to be not less than five (5) business days, nor more
than ten (10) business days, after the date of the Purchase Notice), and the
fair market value to be paid for such Shares.  The Participant (or the
Participant's spouse, to the extent such spouse has physical possession of the
Shares) shall, prior to the close of business on the date specified for the
purchase, deliver to the Corporate Secretary of the Corporation the certificates
representing the shares to be purchased, each certificate to be properly
endorsed for transfer.  To the extent any of the shares to be purchased by the
Corporation are at the time held in escrow under Article VII, the certificates
for such shares shall be promptly delivered out of escrow to the Corporation. 
The Corporation shall, concurrently with the receipt of the stock certificates,
pay to the Participant's spouse (in cash or cash equivalents) an amount equal to
the fair market value specified for such shares in the Purchase Notice.

              If the Participant's spouse does not agree with the fair market
value specified for the shares in the Purchase Notice, then the spouse shall
promptly notify the Corporation in writing of such disagreement and the fair
market value of such 


                                    -15-

<PAGE>

shares shall thereupon be determined by an appraiser of recognized standing 
selected by the Corporation and the spouse.  If they cannot agree on an 
appraiser within twenty (20) days after the date of the Purchase Notice, each 
shall select an appraiser of recognized standing, and the two appraisers 
shall designate a third appraiser of recognized standing whose appraisal 
shall be determinative of such value.  The cost of the appraisal shall be 
shared equally by the Corporation and the Participant's spouse.  The closing 
shall then be held on the fifth business day following the completion of such 
appraisal; PROVIDED, however, that if the appraised value is more than 
fifteen percent (15%) greater than the fair market value specified for the 
shares in the Purchase Notice, the Corporation shall have the right, 
exercisable prior to the expiration of such five (5) business-day period, to 
rescind the exercise of the Special Purchase Right and thereby revoke its 
election to purchase the shares awarded to the spouse.

              8.4    LAPSE.  The Special Purchase Right under this Article VIII
shall lapse and cease to have effect upon the EARLIER to occur of (i) the first
date on which the First Refusal Right under Article VI lapses or (ii) the
expiration of the thirty (30)-day exercise period specified in paragraph 8.3, to
the extent the Special Purchase Right is not timely exercised in accordance with
such paragraph.

       IX.    GENERAL PROVISIONS

              9.1    ASSIGNMENT.  The Corporation may assign its Repurchase
Right under Article V, its First Refusal Right under Article VI and/or its
Special Purchase Right under Article VIII to any person or entity selected by
the Corporation's Board of Directors, including (without limitation) one or more
shareholders of the Corporation.

              If the assignee of the Repurchase Right is other than a one
hundred percent (100%) owned subsidiary corporation of the Corporation or the
parent corporation owning one hundred percent (100%) of the Corporation, then
such assignee must make a cash payment to the Corporation, upon the assignment
of the Repurchase Right, in an amount equal to the excess (if any) of (i) the
fair market value of the Unvested Shares at the time subject to the assigned
Repurchase Right over (ii) the aggregate repurchase price payable for Unvested
Shares thereunder.

              9.2    DEFINITIONS.  For purposes of this Agreement, the following
provisions shall be applicable in determining the parent and subsidiary
corporations of the Corporation:

                   (i)      Any corporation (other than the Corporation) in an
       unbroken chain of corporations 


                                    -16-


<PAGE>


       ending with the Corporation shall be considered to be a PARENT         
       corporation of the Corporation, provided each such corporation in the  
       unbroken chain (other than the Corporation) owns, at the time of the   
       determination, stock possessing fifty percent (50%) or more of the     
       total combined voting power of all classes of stock in one of the      
       other corporations in such chain.

                  (ii)      Each corporation (other than the Corporation) in an
       unbroken chain of corporations beginning with the Corporation shall be
       considered to be a SUBSIDIARY of the Corporation, provided each such

                                 GENERAL PROVISIONS


     I.   PURPOSE OF THE PLAN

          This 1999 Stock Incentive Plan is intended to promote the interests 
of Rubio's Restaurants, Inc., a Delaware corporation, by providing eligible 
persons in the Corporation's service with the opportunity to acquire a 
proprietary interest, or otherwise increase their proprietary interest, in 
the Corporation as an incentive for them to remain in such service.

          Capitalized terms shall have the meanings assigned to such terms in 
the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into five separate equity programs:

          -    the Discretionary Option Grant Program under which eligible 
persons may, at the discretion of the Plan Administrator, be granted options 
to purchase shares of Common Stock,

          -    the Salary Investment Option Grant Program under which 
eligible employees may elect to have a portion of their base salary invested 
each year in special option grants, 

          -    the Stock Issuance Program under which eligible persons may, 
at the discretion of the Plan Administrator, be issued shares of Common Stock 
directly, either through the immediate purchase of such shares or as a bonus 
for services rendered the Corporation (or any Parent or Subsidiary),

          -    the Automatic Option Grant Program under which eligible 
non-employee Board members shall automatically receive option grants at 
designated intervals over their period of continued Board service, and 

          -    the Director Fee Option Grant Program under which non-employee 
Board members may elect to have all or any portion of their annual retainer 
fee otherwise payable in cash applied to a special stock option grant.  

<PAGE>

          B.   The provisions of Articles One and Seven shall apply to all 
equity programs under the Plan and shall govern the interests of all persons 
under the Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   The Primary Committee shall have sole and exclusive authority 
to administer the Discretionary Option Grant and Stock Issuance Programs with 
respect to Section 16 Insiders. Administration of the Discretionary Option 
Grant and Stock Issuance Programs with respect to all other persons eligible 
to participate in those programs may, at the Board's discretion, be vested in 
the Primary Committee or a Secondary Committee, or the Board may retain the 
power to administer those programs with respect to all such persons.  
However, the Board acting by a disinterested majority shall have the 
exclusive authority to make any discretionary option grants or stock 
issuances to members of the Primary Committee. 

          B.   Members of the Primary Committee or any Secondary Committee 
shall serve for such period of time as the Board may determine and may be 
removed by the Board at any time.  The Board may also at any time terminate 
the functions of any Secondary Committee and reassume all powers and 
authority previously delegated to such committee.

          Each Plan Administrator shall, within the scope of its 
administrative functions under the Plan, have full power and authority 
(subject to the provisions of the Plan) to establish such rules and 
regulations as it may deem appropriate for proper administration of the 
Discretionary Option Grant and Stock Issuance Programs and to make such 
determinations under, and issue such interpretations of, the provisions of 
those programs and any outstanding options or stock issuances thereunder as 
it may deem necessary or advisable.  Decisions of the Plan Administrator 
within the scope of its administrative functions under the Plan shall be 
final and binding on all parties who have an interest in the Discretionary 
Option Grant and Stock Issuance Programs under its jurisdiction or any option 
or stock issuance thereunder.

          C.   The Primary Committee shall have the sole and exclusive 
authority to determine which Section 16 Insiders and other highly compensated 
Employees shall be eligible for participation in the Salary Investment Option 
Grant Program for one or more calendar years.  However, all option grants 
under the Salary Investment Option Grant Program shall be made in accordance 
with the express terms of that program, and the Primary Committee shall not 
exercise any discretionary functions with respect to the option grants made 
under that program.

          D.   Service on the Primary Committee or the Secondary Committee 
shall constitute service as a Board member, and members of each such 
committee shall accordingly be entitled to full indemnification and 
reimbursement as Board members for their service on such committee.  No 
member of the Primary Committee or the Secondary Committee shall be liable 
for any act or omission made in good faith with respect to the Plan or any 
option grants or stock issuances under the Plan.

          E.   Administration of the Automatic Option Grant and Director Fee 
Option Grant Programs shall be self-executing in accordance with the terms of 
those programs, and no Plan Administrator shall exercise any discretionary 
functions with respect to any option grants or stock issuances made under 
those programs.

                         (ii)  non-employee members of the Board or
          the board of directors of any Parent or Subsidiary, and

                         (iii) consultants and other independent
          advisors who provide services to the Corporation (or any
          Parent or Subsidiary).

          B.   Only Employees who are Section 16 Insiders or other highly 
compensated individuals shall be eligible to participate in the Salary 
Investment Option Grant Program.

          C.   Each Plan Administrator shall, within the scope of its 
administrative jurisdiction under the Plan, have full authority to determine, 
(i) with respect to the option grants under the Discretionary Option Grant 
Program, which eligible persons are to receive such grants, the time or times 
when those grants are to be made, the number of shares to be covered by each 
such grant, the status of the granted option as either an Incentive Option or 
a Non-Statutory Option, the time or times when each option is to become 
exercisable, the vesting schedule (if any) applicable to the option shares 
and the maximum term for which the option is to remain outstanding and (ii) 
with respect to stock issuances under the Stock Issuance Program, which 
eligible persons are to receive such issuances, the time or times when the 
issuances are to be made, the number of shares to be issued to each 
Participant, the vesting schedule (if any) applicable to the issued shares 
and the consideration for such shares.

          D.   The Plan Administrator shall have the absolute discretion 
either to grant options in accordance with the Discretionary Option Grant 
Program or to effect stock issuances in accordance with the Stock Issuance 
Program.

          E.   The individuals who shall be eligible to participate in the 
Automatic Option Grant Program shall be limited to (i) those individuals who 
first become non-employee Board members on or after the Underwriting Date, 
whether through appointment by the Board or election by the Corporation's 
stockholders, and (ii) those individuals who continue to serve as 
non-employee Board members at one or more Annual Stockholders Meetings held 
after the Underwriting Date.  A non-employee Board member who has previously 
been in the employ of the Corporation (or any Parent or Subsidiary) shall not 
be eligible to receive an option grant under the Automatic Option Grant 
Program at the time he or she first becomes a non-employee Board member, but 
shall be eligible to receive periodic option grants under the Automatic 
Option Grant Program while he or she continues to serve as a non-employee 
Board member. 

          F.   All non-employee Board members shall be eligible to 
participate in the Director Fee Option Grant Program.

Common Stock initially reserved for issuance over the term of the Plan shall

stockholders, including the shares subject to outstanding options under that 
Predecessor Plans, (ii) plus an additional increase of  approximately 500,000 
shares to be approved by the Corporation's stockholders prior to the 
Underwriting Date.

          B.   The number of shares of Common Stock available for issuance 
under the Plan shall automatically increase on the first trading day of 
January each calendar year during the term of the Plan, beginning with 
calendar year 2000, by an amount equal to three percent (3%) of the total 
number of shares of Common Stock outstanding on the last trading day in 
December of the immediately preceding calendar year, but in no event shall 
any such annual increase exceed 450,000 shares.

          C.   No one person participating in the Plan may receive options, 
separately exercisable stock appreciation rights and direct stock issuances 
for more than 500,000 shares of Common Stock in the aggregate per calendar 
year.

          D.   Shares of Common Stock subject to outstanding options 
(including options incorporated into this Plan from the Predecessor Plans) 
shall be available for subsequent issuance under the Plan to the extent (i) 
those options expire or terminate for any reason prior to exercise in full or 
(ii) the options are cancelled in accordance with the cancellation-regrant 
provisions of Article Two.  Unvested shares issued under the Plan and 
subsequently cancelled or repurchased by the Corporation at the original 
issue price paid per share, pursuant to the Corporation's repurchase rights 
under the Plan shall be added back to the number of shares of Common Stock 
reserved for issuance under the Plan and shall accordingly be available for 
reissuance through one or more subsequent option grants or direct stock 
issuances under the Plan.  However, should the exercise price of an option 
under the Plan be paid with shares of Common Stock or should shares of Common 
Stock otherwise issuable under the Plan be withheld by the Corporation in 
satisfaction of the withholding taxes incurred in connection with the 
exercise of an option or the vesting of a stock issuance under the Plan, then 
the number of shares of Common Stock available for issuance under the Plan 
shall be reduced by the gross number of shares for which the option is 
exercised or which vest under the stock issuance, and not by the net number 
of shares of Common Stock issued to the holder of such option or stock 
issuance. Shares of Common Stock underlying one or more stock appreciation 
rights exercised under Section IV of Article Two, Section III of Article 
Three, Section II of Article Five or Section III of Article Six of the Plan 
shall NOT be available for subsequent issuance under the Plan.

          E.   If any change is made to the Common Stock by reason of any 
stock split, stock dividend, recapitalization, combination of shares, 
exchange of shares or other change affecting the outstanding Common Stock as 
a class without the Corporation's receipt of 


                                      4.

consideration, appropriate adjustments shall be made by the Plan 
Administrator to (i) the maximum number and/or class of securities issuable 
under the Plan, (ii) the number and/or class of securities for which any one 
person may be granted stock options, separately exercisable stock 
appreciation rights and direct stock issuances under the Plan per calendar 
year, (iii) the number and/or class of securities for which grants are 
subsequently to be made under the Automatic Option Grant Program to new and 
continuing non-employee Board members, (iv) the number and/or class of 
securities and the exercise price per share in effect under each outstanding 
option under the Plan, (v) the number and/or class of securities and price 
per share in effect under each outstanding option incorporated into this Plan 
from the Predecessor Plans and (vi) the maximum number and/or class of 
securities by which the share reserve is to increase automatically each 
calendar year pursuant to the provisions of Section V.B of this Article One.  
Such adjustments to the outstanding options are to be effected in a manner 
which shall preclude the enlargement or dilution of rights and benefits under 
such options. The adjustments determined by the Plan Administrator shall be 
final, binding and conclusive.

                      DISCRETIONARY OPTION GRANT PROGRAM

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form 
approved by the Plan Administrator; PROVIDED, however, that each such 
document shall comply with the terms specified below.  Each document 
evidencing an Incentive Option shall, in addition, be subject to the 
provisions of the Plan applicable to such options.

          A.   EXERCISE PRICE.

               1.   The exercise price per share shall be fixed by the Plan 
Administrator but shall not be less than one hundred percent (100%) of the 
Fair Market Value per share of Common Stock on the option grant date. 

               2.   The exercise price shall become immediately due upon 
exercise of the option and shall, subject to the provisions of Section I of 
Article Seven and the documents evidencing the option, be payable in one or 
more of the forms specified below:

                    (i)   cash or check made payable to the
          Corporation,

                    (ii)  shares of Common Stock held for the
          requisite period necessary to avoid a charge to the
          Corporation's earnings for financial reporting purposes and
          valued at Fair Market Value on the Exercise Date, or

                    (iii) to the extent the option is exercised
          for vested shares, through a special sale and remittance
          procedure pursuant to which the Optionee shall concurrently
          provide irrevocable instructions to (a) a Corporation-
          designated brokerage firm to effect the immediate sale of
          the purchased shares and remit to the Corporation, out of
          the sale proceeds available on the settlement date,
          sufficient funds to cover the aggregate exercise price
          payable for the purchased shares plus all applicable
          Federal, state and local income and employment taxes
          required to be withheld by the Corporation by reason of such
          exercise and (b) the Corporation to deliver the certificates
          for the purchased shares directly to such brokerage firm in
          order to complete the sale. 

          Except to the extent such sale and remittance procedure is 
utilized, payment of the exercise price for the purchased shares must be made 
on the Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be 
exercisable at such time or times, during such period and for such number of 
shares as shall be determined by the Plan Administrator and set forth in the 
documents evidencing the option.  However, no option shall have a term in 
excess of ten (10) years measured from the option grant date.  


                                      6.

<PAGE>

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   The following provisions shall govern the exercise of any 
options held by the Optionee at the time of cessation of Service or death:

                    (i)   Any option outstanding at the time of
          the Optionee's cessation of Service for any reason shall
          remain exercisable for such period of time thereafter as
          shall be determined by the Plan Administrator and set forth
          in the documents evidencing the option, but no such option
          shall be exercisable after the expiration of the option
          term.

                    (ii)  Any option held by the Optionee at the
          time of death and exercisable in whole or in part at that
          time may be subsequently exercised by the personal
          representative of the Optionee's estate or by the person or
          persons to whom the option is transferred pursuant to the
          Optionee's will or in accordance with the laws of descent
          and distribution or by the Optionee's designated beneficiary
          or beneficiaries of that option.

                    (iii) Should the Optionee's Service be
          terminated for Misconduct, then all outstanding options held
          by the Optionee shall terminate immediately and cease to be
          outstanding.

                    (iv)  During the applicable post-Service
          exercise period, the option may not be exercised in the
          aggregate for more than the number of vested shares for
          which the option is exercisable on the date of the
          Optionee's cessation of Service.  Upon the expiration of the
          applicable exercise period or (if earlier) upon the
          expiration of the option term, the option shall terminate
          and cease to be outstanding for any vested shares for which
          the option has not been exercised.  However, the option
          shall, immediately upon the Optionee's cessation of Service,
          terminate and cease to be outstanding to the extent the
          option is not otherwise at that time exercisable for vested
          shares.

               2.   The Plan Administrator shall have complete discretion, 
exercisable either at the time an option is granted or at any time while the 
option remains outstanding, to:

                    (i)   extend the period of time for which
          the option is to remain exercisable following the Optionee's
          cessation of Service from the limited exercise period
          otherwise in effect for that option to such greater period
          of time as the Plan Administrator shall deem appropriate,
          but in no event beyond the expiration of the option term,
          and/or

                    (ii)  permit the option to be exercised,
          during the applicable post-Service exercise period, not only
          with respect to the number of vested shares of Common Stock
          for which such option is exercisable at the time of the
          Optionee's cessation of Service but also with respect to one
          or more additional installments in which the Optionee would
          have vested had the Optionee continued in Service.


                                      7.

<PAGE>

          D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no 
stockholder rights with respect to the shares subject to the option until 
such person shall have exercised the option, paid the exercise price and 
become a holder of record of the purchased shares.

          E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the 
discretion to grant options which are exercisable for unvested shares of 
Common Stock.  Should the Optionee cease Service while holding such unvested 
shares, the Corporation shall have the right to repurchase, at the exercise 
price paid per share, any or all of those unvested shares.  The terms upon 
which such repurchase right shall be exercisable (including the period and 
procedure for exercise and the appropriate vesting schedule for the purchased 
shares) shall be established by the Plan Administrator and set forth in the 
document evidencing such repurchase right.  

          F.   LIMITED TRANSFERABILITY OF OPTIONS.  

               1.   During the lifetime of the Optionee, Incentive Options 
shall be exercisable only by the Optionee and shall not be assignable or 
transferable other than by will or by the laws of descent and distribution 
following the Optionee's death.  However, a Non-Statutory Option may, in 
connection with the Optionee's estate plan, be assigned in whole or in part 
during the Optionee's lifetime to one or more members of the Optionee's 
immediate family or to a trust established exclusively for one or more such 
family members.  The assigned portion may only be exercised by the person or 
persons who acquire a proprietary interest in the option pursuant to the 
assignment. The terms applicable to the assigned portion shall be the same as 
those in effect for the option immediately prior to such assignment and shall 
be set forth in such documents issued to the assignee as the Plan 
Administrator may deem appropriate.  

               2.   The Optionee may also designate one or more persons as 
the beneficiary or beneficiaries of his or her outstanding options under this 
Article Two, and  those options shall, in accordance with such designation, 
automatically be transferred to such beneficiary or beneficiaries upon the 
Optionee's death while holding those options.  Such beneficiary or 
beneficiaries shall take the transferred options subject to all the terms and 
conditions of the applicable agreement evidencing each such transferred 
option, including (without limitation) the limited time period during which 
the option may be exercised following the Optionee's death.

          II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive 
Options.  Except as modified by the provisions of this Section II, all the 
provisions of Articles One, Two and Seven shall be applicable to Incentive 
Options.  Options which are specifically designated as Non-Statutory Options 
when issued under the Plan shall NOT be subject to the terms of this Section 
II.

          A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.


                                      8.

<PAGE>

          B.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the 
shares of Common Stock (determined as of the respective date or dates of 
grant) for which one or more options granted to any Employee under the Plan 
(or any other option plan of the Corporation or any Parent or Subsidiary) may 
for the first time become exercisable as Incentive Options during any one 
calendar year shall not exceed the sum of One Hundred Thousand Dollars 
($100,000).  To the extent the Employee holds two (2) or more such options 
which become exercisable for the first time in the same calendar year, the 
foregoing limitation on the exercisability of such options as Incentive 
Options shall be applied on the basis of the order in which such options are 
granted.

          C.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option 
is granted is a 10% Stockholder, then the exercise price per share shall not 
be less than one hundred ten percent (110%) of the Fair Market Value per 
share of Common Stock on the option grant date, and the option term shall not 
exceed five (5) years measured from the option grant date.

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding 
option shall automatically accelerate so that each such option shall, 
immediately prior to the effective date of the Corporate Transaction, become 
fully exercisable for the total number of shares of Common Stock at the time 
subject to such option and may be exercised for any or all of those shares as 
fully vested shares of Common Stock.  However, an outstanding option shall 
NOT become exercisable on such an accelerated basis if and to the extent:  
(i) such option is, in connection with the Corporate Transaction, to be 
assumed by the successor corporation (or parent thereof) or (ii) such option 
is to be replaced with a cash incentive program of the successor corporation 
which preserves the spread existing at the time of the Corporate Transaction 
on any shares for which the option is not otherwise at that time exercisable 
and provides for subsequent payout in accordance with the same 
exercise/vesting schedule applicable to those option shares or (iii) the 
acceleration of such option is subject to other limitations imposed by the 
Plan Administrator at the time of the option grant. 

          B.   All outstanding repurchase rights shall automatically 
terminate, and the shares of Common Stock subject to those terminated rights 
shall immediately vest in full, in the event of any Corporate Transaction, 
except to the extent: (i) those repurchase rights are to be assigned to the 
successor corporation (or parent thereof) in connection with such Corporate 
Transaction or (ii) such accelerated vesting is precluded by other 
limitations imposed by the Plan Administrator at the time the repurchase 
right is issued.  

          C.   Immediately following the consummation of the Corporate 
Transaction, all outstanding options shall terminate and cease to be 
outstanding, except to the extent assumed by the successor corporation (or 
parent thereof).

          D.   Each option which is assumed in connection with a Corporate 
Transaction shall be appropriately adjusted, immediately after such Corporate 
Transaction, to apply to the number and class of securities which would have 
been issuable to the Optionee in consummation of such Corporate Transaction 
had the option been exercised immediately prior to such Corporate 
Transaction. Appropriate adjustments to reflect such Corporate Transaction 
shall also


                                      9.

<PAGE>

be made to (i) the exercise price payable per share under each outstanding 
option, PROVIDED the aggregate exercise price payable for such securities 
shall remain the same, (ii) the maximum number and/or class of securities 
available for issuance over the remaining term of the Plan and (iii) the 
maximum number and/or class of securities for which any one person may be 
granted stock options, separately exercisable stock appreciation rights and 
direct stock issuances under the Plan per calendar year and (iv) the maximum 
number and/or class of securities by which the share reserve is to increase 
automatically each calendar year.

          E.   The Plan Administrator shall have the discretionary authority 
to structure one or more outstanding options under the Discretionary Option 
Grant Program so that those options shall, immediately prior to the effect 
date of such Corporate Transaction, become fully exercisable for the total 
number of shares of Common Stock at the time subject to those options and may 
be exercised for any or all of those shares as fully vested shares of Common 
Stock, whether or not those options are to be assumed in the Corporate 
Transaction.  In addition, the Plan Administrator shall have the 
discretionary authority to structure one or more of the Corporation's 
repurchase rights under the Discretionary Option Grant Program so that those 
rights shall not be assignable in connection with such Corporate Transaction 
and shall accordingly terminate upon the consummation of such Corporate 
Transaction, and the shares subject to those terminated rights shall 
thereupon vest in full.

          F.   The Plan Administrator shall have full power and authority to 
structure one or more outstanding options under the Discretionary Option 
Grant Program so that those  options shall become fully exercisable for the 
total number of shares of Common Stock at the time subject to those options 
in the event the Optionee's Service is subsequently terminated by reason of 
an Involuntary Termination within a designated period (not to exceed eighteen 
(18) months) following the effective date of any Corporate Transaction in 
which those options are assumed and do not otherwise accelerate.  Any options 
so accelerated shall remain exercisable for fully vested shares until the 
EARLIER of (i) the expiration of the option term or (ii) the expiration of 
the one (1) year period measured from the effective date of the Involuntary 
Termination.  In addition, the Plan Administrator may structure one or more 
of the Corporation's repurchase rights so that those rights shall immediately 
terminate with respect to any shares held by the Optionee at the time of his 
or her Involuntary Termination, and the shares subject to those terminated 
repurchase rights shall accordingly vest in full at that time. 

          G.   The Plan Administrator shall have the discretionary authority 
to structure one or more outstanding options under the Discretionary Option 
Grant Program so that those options shall, immediately prior to the effect 
date of a Change in Control, become fully exercisable for the total number of 
shares of Common Stock at the time subject to those options and may be 
exercised for any or all of those shares as fully vested shares of Common 
Stock. In addition, the Plan Administrator shall have the discretionary 
authority to structure one or more of the Corporation's repurchase rights 
under the Discretionary Option Grant Program so that those rights shall 
terminate automatically upon the consummation of such Change in Control, and 
the shares subject to those terminated rights shall thereupon vest in full.  
Alternatively, the Plan Administrator may condition the automatic 
acceleration of one or more outstanding options under the Discretionary 
Option Grant Program and the termination of one or more of the


                                      10.

<PAGE>

Corporation's outstanding repurchase rights under such program upon the 
subsequent termination of the Optionee's Service by reason of an Involuntary 
Termination within a designated period (not to exceed eighteen (18) months) 
following the effective date of such Change in Control.  Each option so 
accelerated shall remain exercisable for fully vested shares until the 
EARLIER of (i) the expiration of the option term or (ii) the expiration of 
the one (1) year period measured from the effective date of Optionee's 
cessation of Service. 

          H.   The portion of any Incentive Option accelerated in connection 
with a Corporate Transaction or Change in Control shall remain exercisable as 
an Incentive Option only to the extent the applicable One Hundred Thousand 
Dollar ($100,000) limitation is not exceeded.  To the extent such dollar 
limitation is exceeded, the accelerated portion of such option shall be 
exercisable as a Nonstatutory Option under the Federal tax laws.

          I.   The outstanding options shall in no way affect the right of 
the Corporation to adjust, reclassify, reorganize or otherwise change its 
capital or business structure or to merge, consolidate, dissolve, liquidate 
or sell or transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any 
time and from time to time, with the consent of the affected option holders, 
the cancellation of any or all outstanding options under the Discretionary 
Option Grant Program (including outstanding options incorporated from the 
Predecessor Plans) and to grant in substitution new options covering the same 
or different number of shares of Common Stock but with an exercise price per 
share based on the Fair Market Value per share of Common Stock on the new 
grant date.

     V.   STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to 
grant to selected Optionees tandem stock appreciation rights and/or limited 
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of 
tandem stock appreciation rights:

                         (i)   One or more Optionees may be granted
          the right, exercisable upon such terms as the Plan
          Administrator may establish, to elect between the exercise
          of the underlying option for shares of Common Stock and the
          surrender of that option in exchange for a distribution from
          the Corporation in an amount equal to the excess of (a) the
          Fair Market Value (on the option surrender date) of the
          number of shares in which the Optionee is at the time vested
          under the surrendered option (or surrendered portion
          thereof) over (b) the aggregate exercise price payable for
          such shares.

                         (ii)  No such option surrender shall be
          effective unless it is approved by the Plan Administrator,
          either at the time of the actual option surrender or at any
          earlier time.  If the surrender is so approved, then the
          distribution to which the Optionee shall be entitled may be
          made in shares of 


                                      11.

<PAGE>

          Common Stock valued at Fair Market Value on the option surrender date,
          in cash, or partly in shares and partly in cash, as the Plan 
          Administrator shall in its sole discretion deem appropriate.

                         (iii) If the surrender of an option is not
          approved by the Plan Administrator, then the Optionee shall
          retain whatever rights the Optionee had under the
          surrendered option (or surrendered portion thereof) on the
          option surrender date and may exercise such rights at any
          time prior to the LATER of (a) five (5) business days after
          the receipt of the rejection notice or (b) the last day on
          which the option is otherwise exercisable in accordance with
          the terms of the documents evidencing such option, but in no
          event may such rights be exercised more than ten (10) years
          after the option grant date.

          C.   The following terms shall govern the grant and exercise of 
limited stock appreciation rights:

                         (i)   One or more Section 16 Insiders may be
          granted limited stock appreciation rights with respect to
          their outstanding options.

                         (ii)  Upon the occurrence of a Hostile Take-
          Over, each individual holding one or more options with such
          a limited stock appreciation right shall have the
          unconditional right (exercisable for a thirty (30)-day
          period following such Hostile Take-Over) to surrender each
          such option to the Corporation.  In return for the
          surrendered option, the Optionee shall receive a cash
          distribution from the Corporation in an amount equal to the
          excess of (A) the Take-Over Price of the shares of Common
          Stock at the time subject to such option (whether or not the
          Optionee is otherwise vested in those shares) over (B) the
          aggregate exercise price payable for those shares.  Such
          cash distribution shall be paid within five (5) days
          following the option surrender date.

                         (iii) At the time such limited stock
          appreciation right is granted, the Plan Administrator shall
          pre-approve any subsequent exercise of that right in
          accordance with the terms of this Paragraph C.  Accordingly,
          no further approval of the Plan Administrator or the Board
          shall be required at the time of the actual option surrender
          and cash distribution. 


                                      12.

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years (if any) for which the Salary Investment
Option Grant Program is to be in effect and to select the Section 16 Insiders
and other highly compensated Employees eligible to participate in the Salary
Investment Option Grant Program for such calendar year or years.  Each selected
individual who elects to participate in the Salary Investment Option Grant
Program must, prior to the start of each calendar year of participation, file
with the Plan Administrator (or its designate) an irrevocable authorization
directing the Corporation to reduce his or her base salary for that calendar
year by an amount not less than Ten Thousand Dollars ($10,000.00) nor more than
Fifty Thousand Dollars ($50,000.00).   Each individual who files such a timely
authorization shall automatically be granted an option under the Salary
Investment Grant Program on the first trading day in January of the calendar
year for which the salary reduction is to be in effect.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; PROVIDED, however,
that each such document shall comply with the terms specified below.

          A.   EXERCISE PRICE.

                    1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

                    2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program.  Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   NUMBER OF OPTION SHARES.  The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A DIVIDED BY (B x 66-2/3%), where

               X is the number of option shares,

               A is the dollar amount of the reduction in the Optionee's base 
          salary for the calendar year to be in effect pursuant to this 
          program, and

                                      13.
<PAGE>

               B is the Fair Market Value per share of Common Stock on the 
          option grant date. 

          C.   EXERCISE AND TERM OF OPTIONS.  The option shall become
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect.  Each option shall have a
maximum term of ten (10) years measured from the option grant date.  

          D.   EFFECT OF TERMINATION OF SERVICE.  Should the Optionee cease
Service for any reason while holding one or more options under this Article
Three, then each such option shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the EARLIER of (i) the expiration of the ten (10)-year option
term or (ii) the expiration of the three (3)-year period measured from the date
of such cessation of Service.  Should the Optionee die while holding one or more
options under this Article Three, then each such option may be exercised, for
any or all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Service (less any shares subsequently purchased by
Optionee prior to death), by the personal representative of the Optionee's
estate or by the person or persons to whom the option is transferred pursuant to
the Optionee's will or in accordance with the laws of descent and distribution
or by the designated beneficiary or beneficiaries of such option.  Such right of
exercise shall lapse, and the option shall terminate, upon the EARLIER of (i)
the expiration of the ten (10)-year option term or (ii) the three (3)-year
period measured from the date of the Optionee's cessation of Service.  However,
the option shall, immediately upon the Optionee's cessation of Service for any
reason, terminate and cease to remain outstanding with respect to any and all
shares of Common Stock for which the option is not otherwise at that time
exercisable.

     III. CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee 
remains in Service, each outstanding option held by such Optionee under this 
Salary Investment Option Grant Program shall automatically accelerate so that 
each such option shall, immediately prior to the effective date of the 
Corporate Transaction, become fully exercisable for the total number of 
shares of Common Stock at the time subject to such option and may be 
exercised for any or all of those shares as fully-vested shares of Common 
Stock.  Each such outstanding option shall terminate immediately following 
the Corporate Transaction, except to the extent assumed by the successor 
corporation (or parent thereof) in such Corporate Transaction.  Any option so 
assumed and shall remain exercisable for the fully-vested shares until the 
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the 
expiration of the three (3)-year period measured from the date of the 
Optionee's cessation of Service.

          B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Salary
Investment Option Grant Program shall automatically accelerate so that each such
option shall immediately become fully exercisable for the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock.  The option shall
remain so exercisable until the EARLIEST to occur  of (i) the expiration of the
ten 

                                      14.
<PAGE>

(10)-year option term, (ii) the expiration of the three (3)-year period
measured from the date of the Optionee's cessation of Service, (iii) the
termination of the option in connection with a Corporate Transaction  or (iv)
the surrender of the option in connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Salary Investment Option Grant
Program.  The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Take-Over Price of
the shares of Common Stock at the time subject to the surrendered option
(whether or not the Optionee is otherwise at the time vested in those shares)
over (ii) the aggregate exercise price payable for such shares.  Such cash
distribution shall be paid within five (5) days following the surrender of the
option to the Corporation.  The Primary Committee shall, at the time the option
with such limited stock appreciation right is granted under the Salary
Investment Option Grant Program, pre-approve any subsequent exercise of that
right in accordance with the terms of this Paragraph C.  Accordingly, no further
approval of the Primary Committee or the Board shall be required at the time of
the actual option surrender and cash distribution. 

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction. 
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, PROVIDED the aggregate exercise price
payable for such securities shall remain the same.

          E.   The grant of options under the Salary Investment Option Grant
Program shall in no way affect the right of the Corporation to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

     IV.  REMAINING TERMS  

          The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

                               STOCK ISSUANCE PROGRAM
                                          
     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants. 
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.  Shares of Common Stock may also be
issued under the Stock Issuance Program pursuant to share right awards which
entitle the recipients to receive those shares upon the attainment of designated
performance goals.

          A.   PURCHASE PRICE.

                    1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

                    2.   Subject to the provisions of Section I of Article
Seven, shares of Common Stock may be issued under the Stock Issuance Program for
any of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

                         (i)   cash or check made payable to the
          Corporation, or

                         (ii)  past services rendered to the
          Corporation (or any Parent or Subsidiary).

          B.   VESTING PROVISIONS.

                    1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program shall be
determined by the Plan Administrator and incorporated into the Stock Issuance
Agreement.   Shares of Common Stock may also be issued under the Stock Issuance
Program pursuant to share right awards which entitle the recipients to receive
those shares upon the attainment of designated performance goals. 

                    2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to 

                                      16.
<PAGE>

the Participant's unvested shares of Common Stock and (ii) such escrow 
arrangements as the Plan Administrator shall deem appropriate.

                    3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested.  Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

                    4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

                    5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares.  Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares of Common Stock as to which the waiver applies.  Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

                    6.   Outstanding share right awards under the Stock Issuance
Program shall automatically terminate, and no shares of Common Stock shall
actually be issued in satisfaction of those awards, if the performance goals
established for such awards are not attained.  The Plan Administrator, however,
shall have the discretionary authority to issue shares of Common Stock under one
or more outstanding share right awards as to which the designated performance
goals have not been attained.

     II.  CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase rights under the
Stock Issuance Program shall terminate automatically, and all the shares of
Common Stock subject to those terminated rights shall immediately vest in full,
in the event of any Corporate Transaction, except to the extent (i) those
repurchase rights are to be assigned to the successor corporation (or parent
thereof) in connection with such Corporate Transaction or (ii) such accelerated
vesting is precluded by other limitations imposed in the Stock Issuance
Agreement.

          B.   The Plan Administrator shall have the discretionary authority to
structure one or more of the Corporation's repurchase rights under the Stock
Issuance Program so that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock 

                                      17.
<PAGE>

subject to those terminated rights shall immediately vest, in the event the 
Participant's Service should subsequently terminate by reason of an 
Involuntary Termination within a designated period (not to exceed eighteen 
(18) months) following the effective date of any Corporate Transaction in 
which those repurchase rights are assigned to the successor corporation (or 
parent thereof).

          C.   The Plan Administrator shall also have the discretionary
authority to structure one or more of the Corporation's repurchase rights under
the Stock Issuance Program so that those rights shall automatically terminate in
whole or in part, and the shares of Common Stock subject to those terminated
rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                           AUTOMATIC OPTION GRANT PROGRAM

     I.   OPTION TERMS

          A.   GRANT DATES.  Option grants shall be made on the dates specified
below:

                    1.   Each individual who is first elected or appointed as a
non-employee Board member at any time on or after the Underwriting Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase 25,000 shares of Common Stock, provided that
individual has not previously been in the employ of the Corporation or any
Parent or Subsidiary.

                    2.   On the date of each Annual Stockholders Meeting held
after the Underwriting Date, each individual who is to continue to serve as an
Eligible Director, whether or not that individual is standing for re-election to
the Board at that particular Annual Meeting, shall automatically be granted a
Non-Statutory Option to purchase 5,000 shares of Common Stock, provided such
individual has served as a non-employee Board member for at least six (6)
months.  There shall be no limit on the number of such 5,000 share option grants
any one Eligible Director may receive over his or her period of Board service,
and non-employee Board members who have previously been in the employ of the
Corporation (or any Parent or Subsidiary) or who have otherwise received one or
more stock option grants from the Corporation prior to the Underwriting Date
shall be eligible to receive such annual option grants over their period of
continued Board service.

          B.   EXERCISE PRICE.

                    1.   The exercise price per share shall be equal to one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.

                    2.   The exercise price shall be payable in one or more of
the alternative forms authorized under the Discretionary Option Grant Program. 
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   OPTION TERM.  Each option shall have a term of ten (10) years
measured from the option grant date.

          D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be
immediately exercisable for any or all of the option shares as fully-vested
shares.

          E.   LIMITED TRANSFERABILITY OF OPTIONS.  Each option under this
Article Five may, in connection with the Optionee's estate plan, be assigned in
whole or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust established exclusively for one or
more such family members.  The assigned portion may only be 

                                      19.
<PAGE>

exercised by the person or persons who acquire a proprietary interest in the 
option pursuant to the assignment. The terms applicable to the assigned 
portion shall be the same as those in effect for the option immediately prior 
to such assignment and shall be set forth in such documents issued to the 
assignee as the Plan Administrator may deem appropriate.  The Optionee may 
also designate one or more persons as the beneficiary or beneficiaries of his 
or her outstanding options under this Article Three, and  those options 
shall, in accordance with such designation, automatically be transferred to 
such beneficiary or beneficiaries upon the Optionee's death while holding 
those options.  Such beneficiary or beneficiaries shall take the transferred 
options subject to all the terms and conditions of the applicable agreement 
evidencing each such transferred option, including (without limitation) the 
limited time period during which the option may be exercised following the 
Optionee's death.  

          F.   TERMINATION OF BOARD SERVICE.  The Optionee (or, in the event of
Optionee's death, the personal representative of the Optionee's estate or the
person or persons to whom the option is transferred pursuant to the Optionee's
will or in accordance with the laws of descent and distribution or the
designated beneficiary or beneficiaries of such option) shall have a twelve
(12)-month period following the date the Optionee ceases to serve as a Board
member in which to exercise each option the Optionee holds at the time of such
cessation of Board service.  In no event shall the option remain exercisable
after the expiration of the option term.

     II.  CORPORATE TRANSACTION/ CHANGE IN CONTROL/ HOSTILE TAKE-OVER

          A.   Immediately following the consummation of any Corporate
Transaction, each automatic option grant shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          B.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding automatic option grants.  The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option over (ii) the aggregate exercise price
payable for such shares.  Such cash distribution shall be paid within five (5)
days following the surrender of the option to the Corporation.  Stockholder
approval of the Plan shall constitute pre-approval of the grant of each such
limited cash-out right and the subsequent exercise of that right in accordance
with the terms of this Paragraph D.  Accordingly, no approval or consent of the
Board or any Plan Administrator shall be required at the time of the actual
option surrender and cash distribution.

          C.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction. 
Appropriate adjustments shall also be made to the exercise price payable per
share under each outstanding option, PROVIDED the aggregate exercise price
payable for such securities shall remain the same.

                                      20.
<PAGE>

          D.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     III. REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

     I.   OPTION GRANTS

          The Primary Committee shall have the sole and exclusive authority to
determine the calendar year or years for which the Director Fee Option Grant
Program is to be in effect.  For each such calendar year the program is in
effect, each non-employee Board member may elect to apply all or any portion of
the annual retainer fee otherwise payable in cash for his or her service on the
Board for that year to the acquisition of a special option grant under this
Director Fee Option Grant Program.  Such election must be filed with the
Corporation's Chief Financial Officer prior to first day of the calendar year
for which the annual retainer fee which is the subject of that election is
otherwise payable.  Each non-employee Board member who files such a timely
election shall automatically be granted an option under this Director Fee Option
Grant Program on the first trading day in January in the calendar year for which
the annual retainer fee which is the subject of that election would otherwise be
payable in cash. 

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option governed by the terms and
conditions specified below.

          A.   EXERCISE PRICE.

                    1.   The exercise price per share shall be thirty-three and
one-third percent (33-1/3%) of the Fair Market Value per share of Common Stock
on the option grant date.

                    2.   The exercise price shall become immediately due upon
exercise of the option and shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program.  Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   NUMBER OF OPTION SHARES.  The number of shares of Common Stock
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A DIVIDED BY (B x 66-2/3%), where

               X is the number of option shares,

               A is the portion of the annual retainer fee subject to the 
          non-employee Board member's election, and 

                                      22.
<PAGE>

               B is the Fair Market Value per share of Common Stock on the 
          option grant date. 

          C.   EXERCISE AND TERM OF OPTIONS.  The option shall become
exercisable in a series of twelve (12) equal monthly installments upon the
Optionee's completion of each month of Board service over the twelve (12)-month
period measured from the grant date.  Each option shall have a maximum term of
ten (10) years measured from the option grant date.  

          D.   LIMITED TRANSFERABILITY OF OPTIONS.  Each option under this
Article Six may, in connection with the Optionee's estate plan, be assigned in
whole or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust established exclusively for one or
more such family members.  The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.  The Optionee may also designate one or more persons as
the beneficiary or beneficiaries of his or her outstanding options under this
Article Three, and  those options shall, in accordance with such designation,
automatically be transferred to such beneficiary or beneficiaries upon the
Optionee's death while holding those options.  Such beneficiary or beneficiaries
shall take the transferred options subject to all the terms and conditions of
the applicable agreement evidencing each such transferred option, including
(without limitation) the limited time period during which the option may be
exercised following the Optionee's death.  

          E.   TERMINATION OF BOARD SERVICE.  Should the Optionee cease Board
service for any reason (other than death or Permanent Disability) while holding
one or more options under this Director Fee Option Grant Program, then each such
option shall remain exercisable, for any or all of the shares for which the
option is exercisable at the time of such cessation of Board service, until the
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Board service.  However, each option held by the Optionee under this Director
Fee Option Grant Program at the time of his or her cessation of Board service
shall immediately terminate and cease to remain outstanding with respect to any
and all shares of Common Stock for which the option is not otherwise at that
time exercisable. 

          F.   DEATH OR PERMANENT DISABILITY.  Should the Optionee's service as
a Board member cease by reason of death or Permanent Disability, then each
option held by such Optionee under this Director Fee Option Grant Program shall
immediately become exercisable for all the shares of Common Stock at the time
subject to that option, and the option may be exercised for any or all of those
shares as fully-vested shares until the EARLIER of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Board service.

          Should the Optionee die after cessation of Board service but while
holding one or more options under this Director Fee Option Grant Program, then
each such option may be exercised, for any or all of the shares for which the
option is exercisable at the time of the Optionee's cessation of Board service
(less any shares subsequently purchased by Optionee prior 

                                      23.

to death), by the personal representative of the Optionee's estate or by the 
person or persons to whom the option is transferred pursuant to the 
Optionee's will or in accordance with the laws of descent and distribution or 
by the designated beneficiary or beneficiaries of such option.  Such right of 
exercise shall lapse, and the option shall terminate, upon the EARLIER of (i) 
the expiration of the ten (10)-year option term or (ii) the three (3)-year 
period measured from the date of the Optionee's cessation of Board service. 

     III. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction while the Optionee 
remains a Board member, each outstanding option held by such Optionee under 
this Director Fee Option Grant Program shall automatically accelerate so that 
each such option shall, immediately prior to the effective date of the 
Corporate Transaction, become fully exercisable for the total number of 
shares of Common Stock at the time subject to such option and may be 
exercised for any or all of those shares as fully-vested shares of Common 
Stock.  Each such outstanding option shall terminate immediately following 
the Corporate Transaction, except to the extent assumed by the successor 
corporation (or parent thereof) in such Corporate Transaction.  Any option so 
assumed and shall remain exercisable for the fully-vested shares until the 
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the 
expiration of the three (3)-year period measured from the date of the 
Optionee's cessation of Board service.

          B.   In the event of a Change in Control while the Optionee remains in
Service, each outstanding option held by such Optionee under this Director Fee
Option Grant Program shall automatically accelerate so that each such option
shall immediately become fully exercisable for the total number of shares of
Common Stock at the time subject to such option and may be exercised for any or
all of those shares as fully-vested shares of Common Stock.  The option shall
remain so exercisable until the EARLIEST to occur of (i) the expiration of the
ten (10)-year option term, (ii) the expiration of the three (3)-year period
measured from the date of the Optionee's cessation of Board service, (iii) the
termination of the option in connection with a Corporate Transaction  or (iv)
the surrender of the option in connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each
outstanding option granted him or her under the Director Fee Option Grant
Program.  The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Take-Over Price of
the shares of Common Stock at the time subject to each surrendered option
(whether or not the Optionee is otherwise at the time vested in those shares)
over (ii) the aggregate exercise price payable for such shares.  Such cash
distribution shall be paid within five (5) days following the surrender of the
option to the Corporation.  Stockholder approval of the Plan shall constitute
pre-approval of the grant of each such limited cash-out right and the subsequent
exercise of that right in accordance with the terms of this Paragraph C. 
Accordingly, no approval or consent of the Board or any Plan Administrator shall
be required at the time of the actual option surrender and cash distribution.

                                      24.
<PAGE>

          D.   The grant of options under the Director Fee Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

     IV.  REMAINING TERMS  

          The remaining terms of each option granted under this Director Fee
Option Grant Program shall be the same as the terms in effect for option grants
made under the Discretionary Option Grant Program.

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

     II.  TAX WITHHOLDING 

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant or Director Fee Option Grant Program) with the right to use shares
of Common Stock in satisfaction of all or part of the Withholding Taxes to which
such holders may become subject in connection with the exercise of their options
or the vesting of their shares.  Such right may be provided to any such holder
in either or both of the following formats:

               STOCK WITHHOLDING:  The election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

               STOCK DELIVERY:  The election to deliver to the Corporation, at
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

                                      26.
<PAGE>

     III. EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately on the Plan Effective
Date.  However, the Salary Investment Option Grant Program and the Director Fee
Option Grant Program shall not be implemented until such time as the Primary
Committee may deem appropriate.  Options may be granted under the Discretionary
Option Grant at any time on or after the Plan Effective Date.  However, no
options granted under the Plan may be exercised, and no shares shall be issued
under the Plan, until the Plan is approved by the Corporation's stockholders. 
If such stockholder approval is not obtained within twelve (12) months after the
Plan Effective Date, then all options previously granted under this Plan shall
terminate and cease to be outstanding, and no further options shall be granted
and no shares shall be issued under the Plan. 

          B.   The Plan shall serve as the successor to the Predecessor Plans,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plans after the Plan Effective Date.  All options outstanding under
the Predecessor Plans on the Plan Effective Date shall be incorporated into the
Plan at that time and shall be treated as outstanding options under the Plan.
However, each outstanding option so incorporated shall continue to be governed
solely by the terms of the documents evidencing such option, and no provision of
the Plan shall be deemed to affect or otherwise modify the rights or obligations
of the holders of such incorporated options with respect to their acquisition of
shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plans which do not otherwise contain such provisions.

          D.   The Plan shall terminate upon the EARLIEST to occur of (i) March
17, 2009, (ii) the date on which all shares available for issuance under the
Plan shall have been issued as fully-vested shares or (iii) the termination of
all outstanding options in connection with a Corporate Transaction.  Should the
Plan terminate on March 17, 2009, then all option grants and unvested stock
issuances outstanding at that time shall continue to have force and effect in
accordance with the provisions of the documents evidencing such grants or
issuances.

     IV.  AMENDMENT OF THE PLAN 

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification.  In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs
and shares of Common Stock may be issued under the Stock Issuance Program that
are in each instance in excess of the number of shares then available for
issuance under the Plan, provided any excess 

                                      27.
<PAGE>

shares actually issued under those programs shall be held in escrow until 
there is obtained stockholder approval of an amendment sufficiently 
increasing the number of shares of Common Stock available for issuance under 
the Plan.  If such stockholder approval is not obtained within twelve (12) 
months after the date the first such excess issuances are made, then (i) any 
unexercised options granted on the basis of such excess shares shall 
terminate and cease to be outstanding and (ii) the Corporation shall promptly 
refund to the Optionees and the Participants the exercise or purchase price 
paid for any excess shares issued under the Plan and held in escrow, together 
with interest (at the applicable Short Term Federal Rate) for the period the 
shares were held in escrow, and such shares shall thereupon be automatically 
cancelled and cease to be outstanding.

     V.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VI.  REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading. 

     VII. NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

          OO.  WITHHOLDING TAXES shall mean the Federal, state and local income
and employment withholding taxes to which the holder of Non-Statutory Options or
unvested shares of Common Stock may become subject in connection with the
exercise of those options or the vesting of those shares.

                             RUBIO'S RESTAURANTS, INC.
                         1999 EMPLOYEE STOCK PURCHASE PLAN


     I.     PURPOSE OF THE PLAN

            This Employee Stock Purchase Plan is intended to promote the
interests of  Rubio's Restaurants, Inc., a Delaware Corporation, by providing
eligible employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.

            Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.    ADMINISTRATION OF THE PLAN

            The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III.   STOCK SUBJECT TO PLAN

            A. The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market.  The number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall be limited to
Two Hundred Thousand (200,000) shares.

            B. Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and class of securities
issuable under the Plan, (ii) the maximum number and class of securities
purchasable per Participant on any one Purchase Date, (iii) the maximum number
and class of securities purchasable by all Participants in the aggregate on any
one Purchase Date, and (iv) the number and class of securities and the price per
share in effect under each outstanding purchase right in order to prevent the
dilution or enlargement of benefits thereunder.

     IV.    OFFERING PERIODS

            A. Shares of Common Stock shall be offered for purchase under
the Plan through a series of successive offering periods until such time as (i)
the maximum number of shares of Common Stock available for issuance under the
Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated.

                                      
<PAGE>

            B. Each offering period shall be of such duration (not to
exceed twenty-four (24) months) as determined by the Plan Administrator prior to
the start date of such offering period.  However, the initial offering period
shall commence at the Effective Time and terminate on the last business day in
July 2001.  The next offering period shall commence on the first business day in
August 2001, and subsequent offering periods shall commence as designated by the
Plan Administrator.

            C. Each offering period shall be comprised of a series of one
or more successive Purchase Intervals.  Purchase Intervals shall run from the
first business day in February each year to the last business day in July of the
same year and from the first business day in August each year to the last
business day in January of the following year.  However, the first Purchase
Interval in effect under the initial offering period shall commence at the
Effective Time and terminate on the last business day in January 2000.

            D. Should the Fair Market Value per share of Common Stock on
any Purchase Date within an offering period be less than the Fair Market Value
per share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date.  The new
offering period shall have a duration of twenty (24) months, unless a shorter
duration is established by the Plan Administrator within five (5) business days
following the start date of that offering period.

     V.     ELIGIBILITY

            A. Each individual who is an Eligible Employee on the start
date of any offering period under the Plan may enter that offering period on
such start date or on any subsequent Semi-Annual Entry Date within that offering
period, provided he or she qualifies as an Eligible Employee at that time.

            B. Each individual who first becomes an Eligible Employee after
the start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
qualifies as an Eligible Employee.

            C. The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

            D. To participate in the Plan for a particular offering period,
the Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

                                      2.

     VI.    PAYROLL DEDUCTIONS

            A. The payroll deduction authorized by the Participant for
purposes of acquiring shares of Common Stock during an offering period may be
any multiple of one percent (1%) of the Cash Earnings paid to the Participant
during each Purchase Interval within that offering period, up to a maximum of
ten percent (10%).  The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                    (i)   The Participant may, at any time during the
     offering period, reduce his or her rate of payroll deduction to become
     effective as soon as possible after filing the appropriate form with
     the Plan Administrator.  The Participant may not, however, effect more
     than one (1) such reduction per Purchase Interval.

                    (ii)  The Participant may, prior to the commencement
     of any new Purchase Interval within the offering period, increase the
     rate of his or her payroll deduction by filing the appropriate form
     with the Plan Administrator.  The new rate (which may not exceed the
     fifteen percent (10%) maximum) shall become effective on the start
     date of the first Purchase Interval following the filing of such form.

            B. Payroll deductions shall begin on the first pay day
administratively feasible following the Participant's Entry Date into the
offering period and shall (unless sooner terminated by the Participant) continue
through the pay day ending with or immediately prior to the last day of that
offering period.  The amounts so collected shall be credited to the
Participant's book account under the Plan, but no interest shall be paid on the
balance from time to time outstanding in such account.  The amounts collected
from the Participant shall not be required to be held in any segregated account
or trust fund and may be commingled with the general assets of the Corporation
and used for general corporate purposes.

            C. Payroll deductions shall automatically cease upon the
termination of the Participant's purchase right in accordance with the
provisions of the Plan.

            D. The Participant's acquisition of Common Stock under the Plan
on any Purchase Date shall neither limit nor require the Participant's
acquisition of Common Stock on any subsequent Purchase Date, whether within the
same or a different offering period.

     VII.   PURCHASE RIGHTS

            A. GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
separate purchase right for each offering period in which he or she
participates.  The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below.  The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

                                      3.
<PAGE>

            Under no circumstances shall purchase rights be granted under the
Plan to any Eligible Employee if such individual would, immediately after the
grant, own (within the meaning of Code Section 424(d)) or hold outstanding
options or other rights to purchase, stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Corporation or any Corporate Affiliate.

            B. EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall
be automatically exercised in installments on each successive Purchase Date
within the offering period, and shares of Common Stock shall accordingly be
purchased on behalf of each Participant on each such Purchase Date.  The
purchase shall be effected by applying the Participant's payroll deductions for
the Purchase Interval ending on such Purchase Date to the purchase of whole
shares of Common Stock at the purchase price in effect for the Participant for
that Purchase Date.

            C. PURCHASE PRICE.  The purchase price per share at which
Common Stock will be purchased on the Participant's behalf on each Purchase Date
within the offering period shall be equal to eighty-five percent (85%) of the
LOWER of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.

            D. NUMBER OF PURCHASABLE SHARES.  The number of shares of
Common Stock purchasable by a Participant on each Purchase Date during the
offering period shall be the number of whole shares obtained by dividing the
amount collected from the Participant through payroll deductions during the
Purchase Interval ending with that Purchase Date by the purchase price in effect
for the Participant for that Purchase Date.  However, the maximum number of
shares of Common Stock purchasable per Participant on any one Purchase Date
shall not exceed One Thousand Five Hundred (1,500) shares, subject to periodic
adjustments in the event of certain changes in the Corporation's capitalization.
In addition, the maximum aggregate number of shares of Common Stock purchasable
by all Participants on any one Purchase Date shall not exceed Fifty Thousand
(50,000) shares, subject to periodic adjustments in the event of certain changes
in the Corporation's capitalization.  However, the Plan Administrator shall have
the discretionary authority, exercisable prior to the start of any offering
period under the Plan, to increase or decrease the limitations to be in effect
for the number of shares purchasable per Participant and in the aggregate by all
Participants on each Purchase Date during that offering period.

            E. EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not
applied to the  purchase of shares of Common Stock on any Purchase Date because
they are not sufficient to purchase a whole share of Common Stock shall be held
for the purchase of Common Stock on the next Purchase Date.  However, any
payroll deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable per Participant or in the
aggregate on the Purchase Date shall be promptly refunded.
            
                                      4.
<PAGE>

            F. TERMINATION OF PURCHASE RIGHT.  The following provisions
shall govern the termination of outstanding purchase rights:

                    (i)   A Participant may, at any time prior to the
     next scheduled Purchase Date in the offering period, terminate his or
     her outstanding purchase right by filing the appropriate form with the
     Plan Administrator (or its designate), and no further payroll
     deductions shall be collected from the Participant with respect to the
     terminated purchase right.  Any payroll deductions collected during
     the Purchase Interval in which such termination occurs shall, at the
     Participant's election, be immediately refunded or held for the
     purchase of shares on the next Purchase Date.  If no such election is
     made at the time such purchase right is terminated, then the payroll
     deductions collected with respect to the terminated right shall be
     refunded as soon as possible.

                    (ii)  The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the
     offering period for which the terminated purchase right was granted. 
     In order to resume participation in any subsequent offering period,
     such individual must re-enroll in the Plan (by making a timely filing
     of the prescribed enrollment forms) on or before his or her scheduled
     Entry Date into that offering period.

                    (iii) Should the Participant cease to remain an
     Eligible Employee for any reason (including death, disability or
     change in status) while his or her purchase right remains outstanding,
     then that purchase right shall immediately terminate, and all of the
     Participant's payroll deductions for the Purchase Interval in which
     the purchase right so terminates shall be immediately refunded. 
     However, should the Participant cease to remain in active service by
     reason of an approved unpaid leave of absence, then the Participant
     shall have the right, exercisable up until the last business day of
     the Purchase Interval in which such leave commences, to (a) withdraw
     all the payroll deductions collected to date on his or her behalf for
     that Purchase Interval or (b) have such funds held for the purchase of
     shares on his or her behalf on the next scheduled Purchase Date.  In
     no event, however, shall any further payroll deductions be collected
     on the Participant's behalf during such leave.  Upon the Participant's
     return to active service (x) within ninety (90) days following the
     commencement of such leave or (y) prior to the expiration of any
     longer period for which such Participant's right to reemployment with
     the Corporation is guaranteed by either statute or contract, his or
     her payroll deductions under the Plan shall automatically resume at
     the rate in effect at the time the leave began, unless the Participant
     withdraws from the Plan prior to his or her return.  An individual who
     returns to active employment following a leave of absence which
     exceeds in duration the applicable (x) or (y) time period will be
     treated as a new Employee for purposes of subsequent participation in
     the Plan and must accordingly re-enroll in the Plan (by making a
     timely filing of the prescribed enrollment forms) on or before his or
     her scheduled Entry Date into the offering period. 

                                      5.
<PAGE>

            G. CHANGE IN CONTROL.  Each outstanding purchase right shall
automatically be exercised, immediately prior to the effective date of any
Change in Control, by applying the payroll deductions of each Participant for
the Purchase Interval in which such Change in Control occurs to the purchase of
whole shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the LOWER of (i) the Fair Market Value per share of Common
Stock on the Participant's Entry Date into the offering period in which such
Change in Control occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Change in Control.  However, the
applicable limitation on the number of shares of Common Stock purchasable per
Participant shall continue to apply to any such purchase, but not the limitation
applicable to the maximum number of shares of Common Stock purchasable in the
aggregate.

            The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Change in Control, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change in Control.

            H. PRORATION OF PURCHASE RIGHTS.  Should the total number of
shares of Common Stock to be purchased pursuant to outstanding purchase rights
on any particular date exceed the number of shares then available for issuance
under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

            I. ASSIGNABILITY.  The purchase right shall be exercisable only
by the Participant and shall not be assignable or transferable by the
Participant.

            J. STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

     VIII.  TRANSFER RESTRICTIONS
            
            A.   Unless the Plan Administrator determines otherwise prior to 
the start of any offering period, the shares of Common Stock purchased by a 
Participant on each purchase date within that offering period must be held by 
the Participant for at least a one year period following the purchase date.  
Accordingly, the Participant shall not sell, make any short sale of, loan, 
hypothecate, pledge, grant any option for the purchase of, or otherwise 
dispose or transfer for value or otherwise agree to engage in any of the 
foregoing transactions with respect to any shares purchased by the 
Participant under the Plan (the "Purchased Shares") until those shares have 
been held for at least a one year period measured from their applicable 
Purchase Date.  This transfer restriction shall hereafter be referred to as 
the "Holding Period Requirement."
            
                                      6.
<PAGE>

            B. Any new, substituted or additional securities which are, by
reason of any stock split, stock dividend, recapitalization, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration, distributed
with respect to the Purchased Shares shall be immediately subject to the Holding
Period Requirement applicable to those shares.

            C. In order to enforce the Holding Period Requirement, the
Corporation may impose stop-transfer instructions with respect to the Purchased
Shares until the end of the one (1) year period.

            D. The stock certificates for the Purchased Shares shall be
endorsed with the following restrictive legend:

               "The shares represented by this certificate are subject to
     certain transfer restrictions granted to the Corporation and
     accordingly may not be sold, assigned, transferred, encumbered, or in
     any manner disposed of except in conformity with the terms of a
     written agreement between the Corporation and the registered owner of
     the shares.  A copy of such agreement is maintained at the
     Corporation's principal corporate officers."

     IX.    ACCRUAL LIMITATIONS

            A. No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000.00) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

            B. For purposes of applying such accrual limitations to the
purchase rights granted under the Plan, the following provisions shall be in
effect:

                    (i)   The right to acquire Common Stock under each
     outstanding purchase right shall accrue in a series of installments on
     each successive Purchase Date during the offering period on which such
     right remains outstanding.

                    (ii)  No right to acquire Common Stock under any
     outstanding purchase right shall accrue to the extent the Participant
     has already accrued in the same calendar year the right to acquire
     Common Stock under one  or more other purchase rights at a rate equal
     to Twenty-Five Thousand Dollars  ($25,000.00) worth of Common Stock
     (determined on the basis of the Fair Market Value per share on the
     date or dates of grant) for each calendar year such rights were at any
     time outstanding.

                                      7.
<PAGE>

            C. If by reason of such accrual limitations, any purchase right
of a Participant does not accrue for a particular Purchase Interval, then the
payroll deductions which the Participant made during that Purchase Interval with
respect to such purchase right shall be promptly refunded.

            D. In the event there is any conflict between the provisions of
this Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

     X.     EFFECTIVE DATE AND TERM OF THE PLAN

            A. The Plan was adopted by the Board on March 18, 1999 and
shall become effective at the Effective Time, PROVIDED no purchase rights
granted under the Plan shall be exercised, and no shares of Common Stock shall
be issued hereunder, until (i) the Plan shall have been approved by the
stockholders of the Corporation and (ii) the Corporation shall have complied
with all applicable requirements of the 1933 Act (including the registration of
the shares of Common Stock issuable under the Plan on a Form S-8 registration
statement filed with the Securities and Exchange Commission), all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is listed for trading and all other
applicable requirements established by law or regulation.  In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall terminate and have no further force or effect, and all sums collected
from Participants during the initial offering period hereunder shall be
refunded.

            B. Unless sooner terminated by the Board, the Plan shall
terminate upon the EARLIEST of (i) the last business day in July, 2009, (ii) the
date on which all shares available for issuance under the Plan shall have been
sold pursuant to purchase rights exercised under the Plan or (iii) the date on
which all purchase rights are exercised in connection with a Corporate
Transaction.  No further purchase rights shall be granted or exercised, and no
further payroll deductions shall be collected, under the Plan following such
termination.

     XI.    AMENDMENT OF THE PLAN

            A. The Board may alter, amend, suspend or terminate the Plan at
any time to become effective immediately following the close of any Purchase
Interval.  However, the Plan may be amended or terminated immediately upon Board
action, if and to the extent necessary to assure that the Corporation will not
recognize, for financial reporting purposes, any compensation expense in
connection with the shares of Common Stock offered for purchase under the Plan,
should the financial accounting rules applicable to the Plan at the Effective
Time be subsequently revised so as to require the recognition of compensation
expense in the absence of such amendment or termination. 

            B.      In no event may the Board effect any of the following
amendments or revisions to the Plan without the approval of the Corporation's
stockholders: (i) increase the number of shares of Common Stock issuable under
the Plan, except for permissible adjustments in the event of certain changes in
the Corporation's capitalization, (ii) alter the purchase price 

                                      8.
<PAGE>

formula so as to reduce the purchase price payable for the shares of Common 
Stock purchasable under the Plan or (iii) modify the eligibility requirements 
for participation in the Plan.

     XII.   GENERAL PROVISIONS

            A. All costs and expenses incurred in the administration of the
Plan shall be paid by the Corporation; however, each Plan Participant shall bear
all costs and expenses incurred by such individual in the sale or other
disposition of any shares purchased under the Plan.

            B. Nothing in the Plan shall confer upon the Participant any
right to continue in the employ of the Corporation or any Corporate Affiliate
for any period of specific duration or interfere with or otherwise restrict in
any way the rights of the Corporation (or any Corporate Affiliate employing such
person) or of the Participant, which rights are hereby expressly reserved by
each, to terminate such person's employment  at any time for any reason, with or
without cause.

            C. The provisions of the Plan shall be governed by the laws of
the State of California without resort to that State's conflict-of-laws rules.

          The following definitions shall be in effect under the Plan:

all overtime payments, bonuses, commissions, profit-sharing distributions and

shall be calculated before deduction of (A) any income or employment tax
withholdings or (B) any and all contributions made by the Participant to any
Code Section 401(k) salary deferral plan or Code Section 125 cafeteria benefit
program now or hereafter established by the Corporation or any Corporate
Affiliate.   However, Cash Earnings shall NOT include any contributions made on
the Participant's behalf by the Corporation or any Corporate Affiliate to any
employee benefit or welfare plan now or hereafter established (other than Code
Section 401(k) or Code Section 125 contributions).

          C.   CHANGE IN CONTROL shall mean a change in ownership of the
Corporation pursuant to any of the following transactions: 

               (i)   a merger or consolidation in which securities
     possessing more than fifty percent (50%) of the total combined voting
     power of the Corporation's outstanding securities are transferred to a
     person or persons different from the persons holding those securities
     immediately prior to such transaction, or

               (ii)  the sale, transfer or other disposition of all or
