MODTECH, INC.                                                 SPI HOLDINGS, INC.

                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

      The Boards of Directors of Modtech, Inc. and SPI Holdings, Inc. have both
unanimously approved the merger of Modtech and SPI. We are planning to
accomplish the combination through concurrent mergers of Modtech and SPI into
separate subsidiaries of a new holding company, named Modtech Holdings, Inc.,
which is called "Holdings" in this Joint Proxy Statement/Prospectus.

      SPI stockholders will receive 1.8785 shares of Holdings Common Stock for
each share of SPI Common or Preferred Stock they own. Subject to certain
adjustments described in this Joint Proxy Statement/Prospectus, they may elect
to receive $49.4097 per share of SPI stock in place of Holdings Common Stock for
up to 5.9176% of their SPI stock. Modtech stockholders will receive 0.8508
shares of Holdings common stock and $3.7293 in exchange for each share of
Modtech Common Stock held. Subject to certain adjustments described in this
Joint Proxy Statement/Prospectus, they may elect to receive up to 3.94% of their
shares from Holdings as Series A Preferred Stock instead of Holdings Common
Stock. Holdings' Common Stock is substantially identical to the Modtech Common
Stock currently outstanding.

      The merger cannot be completed unless the stockholders of both companies
approve the merger agreement. We have each scheduled special meetings for our
stockholders to vote on the merger agreement. The Boards of Directors of Modtech
and SPI have unanimously determined that the merger of their respective
companies is in the best interest of their stockholders, and each Board
unanimously recommends that you vote FOR approval of the merger agreement. YOUR
VOTE IS VERY IMPORTANT.

      IN DECIDING HOW TO VOTE, YOU SHOULD CONSIDER VARIOUS RISKS WHICH ARE
DESCRIBED IN THIS JOINT PROXY STATEMENT/PROSPECTUS UNDER THE HEADING, "CERTAIN
RISK FACTORS," BEGINNING AT PAGE 15.


      Whether or not you plan to attend your meeting, please vote by completing
the enclosed proxy card and mailing it to us. If you sign, date, and mail your
proxy card without indicating how you want to vote, your proxy will be counted
as a vote in favor of the proposals submitted at your meeting. If your shares
are held in "street name," you must instruct your broker in order to vote. If
you fail to return your proxy card or fail to instruct your broker, you will in
effect vote against the merger agreement.

      The date, times and places of the special meetings are as follows:

                              QUESTIONS AND ANSWERS
                          ABOUT THE MODTECH/SPI MERGER

1.    Q:    WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?

      A:    Modtech and SPI believe that their combination will create value for
            both companies' stockholders through:

      -     Product diversification -- At present, Modtech makes modular
            relocatable classrooms and SPI makes commercial and light industrial
            modular buildings.

      -     Geographic expansion -- Modtech currently does business primarily in
            California and also in Nevada and Arizona. SPI currently does
            business in California, Arizona, Nevada, Colorado, Texas, New Mexico
            and other neighboring states.

      -     Greater efficiencies in operation -- We plan to consolidate certain
            manufacturing and administrative functions of both companies. We
            will seek purchasing, shipping and other efficiencies as a result of
            the Mergers.

      -     Liquidity -- Modtech stockholders will receive a total of
            $39,923,742 in cash. SPI stockholders will receive publicly traded
            stock in Holdings in exchange for their investment in SPI, which is
            a privately held company. SPI stockholders will also receive a total
            of $8,076,133 in cash.

2.    Q:    HOW ARE THE COMPANIES MERGING?

      A:    They are merging through concurrent mergers with separate
            subsidiaries of Holdings.

3.    Q:    HOW DOES HOLDINGS DIFFER FROM MODTECH?

      A:    Once the Mergers occur, Holdings will be the holding company owning
            both Modtech and SPI. Holdings will be a Delaware corporation.
            Modtech is a California corporation. Holdings common stock will be
            substantially the same as Modtech's existing common stock. The
            Holdings Board of Directors will consist of nine members, including
            four current directors of Modtech (Evan M. Gruber, Charles C.
            McGettigan, Myron A. Wick III, and Daniel J. Donahoe III); three
            current directors of SPI, (Patrick Van Den Bossche, Charles A.
            Hamilton and Charles R. Gwirtsman); and two outside directors who
            have not yet been selected. Evan M. Gruber, Chief Executive Officer
            of Modtech, will serve as the Chief Executive Officer of Holdings,
            and Michael G. Rhodes, Chief Operating Officer of Modtech, will
            serve as Chief Operating Officer and Chief Financial Officer of
            Holdings. They will be joined by Patrick Van Den Bossche, President
            of SPI, who will hold the same position at Holdings.

4.    Q:    WHAT WILL I RECEIVE FOR MY STOCK?

      A:    Modtech stockholders will receive $3.7293 and 0.8508 shares of
            Holdings Common Stock for each share of Modtech Common Stock they
            own at the time of the Mergers. In place of shares of Holdings
            Common Stock, Modtech stockholders may elect to receive the same
            number of shares of Holdings Series A Preferred Stock for up to
            3.94% of their shares of Modtech Common Stock. The number of shares
            of Holdings Series A Preferred Stock that Modtech stockholders may
            elect to receive will be

            adjusted in accordance with the Merger Agreement.

            SPI stockholders will receive 1.8785 shares of Holdings Common Stock
            for each share of SPI Common or Preferred stock that they own. Each
            SPI stockholder may elect to receive, in place of Holdings Common
            Stock, $49.4097 per share of SPI stock for up to 5.9176% of the
            total shares of SPI Common Stock and SPI Preferred Stock they own.

            The cash to be paid and the shares to be issued in the Mergers is
            sometimes referred to in this Joint Proxy Statement/Prospectus as
            the "Merger Consideration." With respect to the Modtech Merger, the
            cash and shares is sometimes referred to as the "Modtech Merger
            Consideration," and, with respect to the SPI Merger, as the "SPI
            Merger Consideration."

5.    Q:    WILL HOLDINGS COMMON STOCK BE LISTED FOR TRADING ON THE NASDAQ
            NATIONAL MARKET?

      A:    Yes, Holdings Common Stock will be listed on the Nasdaq National
            Market, but Holdings Series A Preferred Stock will not be listed.

6.    Q:    HOW DO I ELECT TO RECEIVE CASH FOR A PORTION OF MY SHARES?

      A:    SPI Stockholders: You will make your election on the letter of
            transmittal we will send to you through ChaseMellon Shareholder
            Services LLC, our Exchange Agent for the Mergers. In order for your
            election to be effective, you must send in your SPI stock
            certificates along with the letter of transmittal. You may make
            different elections for each share of SPI Common or Preferred Stock
            (collectively, "SPI Capital Stock") that you own. If you do not make
            an election on the letter of transmittal, you will receive 1.8785
            shares of Holdings Common Stock for each share of SPI Capital Stock
            that you own.

            Modtech Stockholders: You may not make an election to receive a
            different proportion of cash and securities. You will receive
            $3.7293 and 0.8508 shares of Holdings Common Stock for each share of
            Modtech Common Stock you own. However, you may elect to receive
            Holdings Series A Preferred Stock in place of Holdings Common Stock
            for up to 3.94% of your shares of Modtech Common Stock. You will
            make your elections when you send in your Modtech stock certificate
            with the letter of transmittal that the Exchange Agent will send to
            you shortly after the Mergers are completed.

7.    Q:    WHY ARE MODTECH STOCKHOLDERS BEING OFFERED THE RIGHT TO SELECT
            HOLDINGS SERIES A PREFERRED STOCK IN PLACE OF HOLDINGS COMMON STOCK?

      A:    Holdings Series A Preferred Stock is being offered in order for the
            Modtech Merger to meet the requirements of Section 351 of the
            Internal Revenue Code and is being offered to all Modtech
            stockholders because California law requires all stockholders in a
            merger be offered the same consideration. Because the Holdings
            Series A Preferred Stock does not have voting rights and will not be
            listed on any exchange (See "Description of Holdings Capital
            Stock"), it is anticipated that no Modtech stockholders, other than
            Proactive Partners, L.P. and Lagunitas Partners, will select
            Holdings Series A Preferred Stock in place of Holdings Common Stock.
            Proactive Partners, L.P., and Lagunitas Partners have agreed to
            accept all of Holdings Series A Preferred Stock offered in order for
            the Modtech Merger to meet the requirements

   11

            of Section 351 of the Internal Revenue Code.

8.    Q:    IF I AM AN SPI STOCKHOLDER AND ELECT TO RECEIVE $49.4097 A SHARE FOR
            UP TO 5.9176% OF MY SHARES, CAN I BE REQUIRED TO ACCEPT MORE CASH?

      A:    Yes. The Merger Agreement requires that the total cash elected by
            SPI stockholders must equal $8,076,133. If the total cash does not
            equal $8,076,133, additional shares of SPI Common and Preferred
            Stock will be converted to cash at $49.4097 per share pro rata among
            SPI stockholders who elected to receive cash for some of their
            shares until the total cash to be paid for SPI Capital Stock equals
            $8,076,133. In such a case, stockholders who elected to receive cash
            for less than 5.9176% of the shares, as well as stockholders who
            elected to receive cash for 5.9176% of their shares, may be required
            to accept more cash.

9.    Q:    IF I AM AN SPI STOCKHOLDER, CAN I ELECT TO RECEIVE $49.4097 A SHARE
            FOR MORE THAN 5.9176% OF MY SHARES?

      A:    No. You may not voluntarily elect to receive cash for more than
            5.9176% of your shares, although you may be required to accept cash
            for more shares as stated in the preceding answer.

10.   Q:    IF I AM AN SPI STOCKHOLDER AND DO NOT ELECT TO RECEIVE $49.4097 A
            SHARE FOR ANY OF MY SHARES, CAN I BE REQUIRED TO ACCEPT CASH?

      A:    Yes. If all those SPI stockholders who elected to convert a portion
            of their shares to cash have all of their remaining shares converted
            to cash and the total cash to be paid for shares of SPI Capital
            Stock is still less than $8,076,133, then stockholders who did not
            elect to have any shares converted to cash will have their shares
            converted to cash pro rata based on all remaining shares not yet
            converted to cash until the total cash to be paid equals $8,076,133.


11.   Q:    HOW WILL FRACTIONAL SHARES BE HANDLED?

      A:    Holdings will not issue fractional shares. Instead, Holdings will
            pay cash to each SPI stockholder and Modtech stockholder who would
            otherwise be entitled to receive a fractional share of Holdings
            Common Stock. The payment will be based on the closing price of
            Modtech Common Stock on the last trading day on the Nasdaq National
            Market prior to the completion of the Mergers. Each Modtech
            stockholder who would otherwise be entitled to receive a fractional
            share of Holdings Series A Preferred Stock will receive shares of
            Holdings Series A Preferred Stock rounded upward to the nearest
            number of whole shares.

12.   Q:    WHAT ARE THE TAX CONSEQUENCES OF THE MERGERS?

      A:    We have been advised by tax counsel that (1) the cash received in
            the Mergers will be taxable to the stockholders, and (2) the shares
            of Holdings Common Stock and Holdings Series A Preferred Stock will
            be received tax free.

            Tax matters are very complicated and the tax consequences of the
            Mergers will depend on the facts of your own situation. You should
            consult your tax advisors for a full understanding of the tax
            consequences of the Mergers to you. See "The Mergers -- Certain
            Federal Income Tax Consequences."

   12

13.   Q:    SHOULD I SEND IN MY SPI OR MODTECH STOCK CERTIFICATES NOW?

      A:    No. After the Mergers are completed, the Exchange Agent will send
            SPI stockholders and Modtech stockholders written instructions for
            exchanging their stock certificates.

14.   Q:    WHAT DO I NEED TO DO NOW?

      A:    Please mail your signed proxy card in the enclosed postage prepaid
            return envelope as soon as possible, so that your shares may be
            represented and voted at the appropriate stockholders' meeting. YOUR
            VOTE IS VERY IMPORTANT.

            If you sign and send in your proxy and do not indicate how you want
            to vote, your proxy will be counted as a vote in favor of the
            proposals. If you do not vote or you abstain, it will have the
            effect of a vote against the proposals. You may withdraw your proxy
            up to and on the day of your stockholders' meeting by following the
            directions on page 44.

            Modtech's meeting will take place on ___________, December __, 1998
            at 10:00 a.m. and SPI's meeting will take place on ___________,
            December __, 1998 at 10:00 a.m. You should sign and mail your proxy
            card even if you are planning to attend your meeting as you can
            still withdraw your proxy, change your vote or attend your meeting
            and vote in person.

15.   Q:    WHAT AM I BEING ASKED TO VOTE UPON?

      A:    SPI stockholders: You are being asked to approve the Merger
            Agreement which provides that SPI will become, through merger, a
            wholly owned subsidiary of Holdings. It is intended that you will
            receive Holdings' Common Stock tax free, but you will be taxed on
            any cash you may receive. You are urged to consult your own tax
            advisors.

            Modtech stockholders: You are being asked to approve the Merger
            Agreement which provides that Modtech will become, through merger, a
            wholly owned subsidiary of Holdings. It is intended that you will
            receive Holdings Common Stock and, if you elect, Holdings Series A
            Preferred Stock, tax free. You will be taxed on any cash you
            receive. You are urged to consult your own tax advisors.

16.   Q:    HOW MANY SHARES OF HOLDINGS STOCK WILL BE OUTSTANDING AFTER THE
            MERGERS ARE COMPLETED?

      A:    After the Mergers, Holdings is expected to have approximately
            14,844,519 shares outstanding on a fully diluted basis. This
            includes approximately 12,622,158 shares of Common Stock, 388,939
            shares of Series A Preferred Stock and options to acquire 1,833,422
            shares of Common Stock. The options will be currently exercisable
            for approximately 1,325,851 shares.

17.   Q:    WHAT VOTE IS REQUIRED FOR APPROVAL?

      A:    The Mergers must be approved:

      -     by holders of 70% of the votes entitled to be cast by holders of the
            outstanding shares of SPI Common Stock and SPI's Series A-1, A-2,
            A-3, A-4, A-5 and A-6 Preferred Stock, with the Common and Preferred
            Stock voting together as a single class, and

      -     by holders of a majority of the votes entitled to be cast by holders
            of the outstanding shares of Modtech Common Stock.

   13

18.   Q:    WHAT DO THE MODTECH AND SPI BOARDS OF DIRECTORS RECOMMEND?

      A:    Each Board of Directors unanimously approved the Merger Agreement
            and recommends that their company's stockholders vote FOR the
            proposal to approve the Merger Agreement and the Mergers.

19.   Q:    WHAT RISKS SHOULD I CONSIDER?

      A:    The exchange ratios of cash and Holdings shares for SPI and Modtech
            shares are fixed. These exchange ratios will not change even if the
            market price of Modtech Common Stock decreases before the Mergers
            occur. Accordingly, the value of the Holdings stock and cash you
            receive when the Mergers occur may be lower than the current market
            value of Modtech's Common Stock. You should review "Certain Risk
            Factors" on pages 15 through 19, as well as the countervailing
            factors considered by each company's Board of Directors described
            under "The Mergers--Reasons for the Mergers; Recommendations of the
            Boards of Directors."

20.   Q:    WHEN ARE THE MERGERS EXPECTED TO OCCUR?

      A:    We are working to complete the Mergers by the end of 1998.

21.   Q:    WHAT WILL HOLDINGS DIVIDEND POLICY BE?

      A:    Holdings will continue Modtech's dividend policy. Modtech has not
            declared a cash dividend to common stockholders since 1990 and has
            no present intention to pay a dividend in the future.

22.   Q:    IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
            VOTE MY SHARES FOR ME?

      A:    Your broker will vote your shares only if you provide instructions
            on how to vote. Otherwise, without instructions, your shares will
            not be voted. Shares that are not voted will have the effect of
            votes against the proposals.

THE COMPANIES

MODTECH, INC.
2830 Barrett Avenue
Perris, California 92571
(909) 943-4014

      Modtech designs, manufactures, markets and installs modular relocatable
classrooms. Based upon 1997 net sales, Modtech believes that it is the largest
manufacturer of modular relocatable classrooms in California. Modtech's
classrooms are sold primarily to California school districts directly and to
third parties and the State of California primarily for lease to California's
school districts. Modtech's classrooms are engineered and constructed in
accordance with structural and seismic safety specifications adopted by the
California Department of State Architects which regulates all school
construction on public land. These standards are more rigorous than the
requirements for other portable units.

      Modtech currently operates a total of seven production lines at five
plants, which serve Arizona and the Northern and Southern California markets.

      Organized in 1982, Modtech maintains an Internet Web site that contains
information concerning its products and personnel and copies of its most recent
press releases at the address "http://www.modt.com."

SPI HOLDINGS, INC.
9550 Hermosa Avenue
Rancho Cucamonga, California 91730
(909) 484-4280

      SPI is a leading designer, manufacturer and wholesaler of commercial and
light industrial modular buildings in the United States. Through its four
manufacturing plants, SPI designs and builds modular buildings to customer
specifications for a wide array of uses, including corporate and professional
office space; governmental, educational, recreational and religious facilities;
and construction site offices. SPI's end users include a number of Fortune 500
companies. SPI's modular buildings serve as temporary, semi-permanent and
permanent facilities and can function as free-standing buildings or additions to
existing structures.

      SPI's modular buildings range in size and complexity from a basic
720-square foot module to a 50,000-square foot building combining several
structures and may contain multiple stories. SPI distributes its products
through national dealers, such as GE Capital Modular Space and Williams
Scotsman, and through multiple regional and local dealers. These dealers lease
(or, less frequently, sell) modular buildings to a diverse end user market.
SPI's operations and sales are presently concentrated in the State of California
and the Southwestern United States.

      SPI's predecessor was founded in 1972. Since August 1997, SPI, through its
operating subsidiary, SPI Manufacturing, Inc., has completed three strategic

                                        6
   15

acquisitions. In its first acquisition, the Company converted the manufacturing
facility of a mobile home builder to a fully operational modular construction
facility to provide additional manufacturing capacity in California. It then
acquired Office Master of Texas, Inc., located in Glen Rose, Texas, and Rosewood
Enterprises, Inc., located in Phoenix, Arizona, both of which are leading
modular building manufacturers in their respective regional markets.

conducted any business. Following the Mergers, Modtech stockholders will own
about 65.9% of Holdings Common Stock and SPI stockholders will own about 34.1%
of Holdings Common Stock. Since Modtech and SPI will become wholly-owned
subsidiaries of Holdings through the Mergers, the business of Holdings will
consist of the businesses of Modtech and SPI. Holdings will be a leading
manufacturer of modular classrooms and commercial and light industrial modular
buildings. Holdings will seek to achieve increased product and geographic
diversification, as well as increased operating efficiencies. Over the next
several years, Holdings will selectively pursue acquisition opportunities in

if that party's Board of Directors determines the third-party proposal is

applicable law to be greater than, equal to, or less than the consideration you
would receive in the Mergers if you did not elect to assert dissenters' rights.

MODTECH

      Modtech is organized under California law. Modtech stockholders who
properly "dissent" from the Mergers by not voting in favor of the Mergers and
otherwise following the procedures required by California law will have the
right to have their shares purchased for their "fair market value" instead of
participating in the Mergers, but only if either their shares are subject to
restrictions on transfer imposed by Modtech or by law or regulation, or if the
holders of 5% or more of Modtech's Common Stock dissent.

      SPI is organized under Colorado law. SPI stockholders who properly
"dissent" from the Mergers will have the right to have their shares purchased
for their "fair value" rather than participating in the Mergers. SPI
stockholders may dissent by not voting in favor of the Mergers and by otherwise
following the procedures required by Colorado law.

OPINION OF MODTECH'S FINANCIAL ADVISOR (PAGE 25)

      In deciding to approve the Mergers, the Modtech Board considered an
opinion from its financial advisor, Donaldson, Lufkin & Jenrette Securities
Corporation, as to the fairness of the consideration to be received by the
Modtech stockholders under the Merger Agreement from a financial point of view.
This opinion is attached as Annex II to this Joint Proxy Statement/Prospectus.
We encourage you to read and consider this opinion carefully, as well as the
information under "The Mergers -- Opinion of Modtech's Financial Advisor." SPI
did not obtain a fairness opinion.

FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE (PAGE 40)

      Modtech and SPI have each made forward-looking statements in this document
(and in documents that are incorporated by reference) that are subject to risks
and uncertainties. Forward-looking statements include the information concerning
possible or assumed future results of operations of Modtech, SPI or Holdings.
Also, when we use words such as "believes," "expects," "anticipates," "intends,"
"plans," "estimates" or similar expressions, we are making forward-looking
statements. Stockholders should note that actual events and results may differ
materially from those expressed in forward-looking statements due to a number of
factors, including changes in legislation relating to funding for modular
classrooms, changes in building code laws or regulations, changes in Federal
income tax laws and general economic and market factors.

                              CERTAIN RISK FACTORS

      In considering whether to approve and adopt the Merger Agreement, the
stockholders of SPI and Modtech should consider, among other risk factors, the
following:

RISKS RELATED TO THE MERGERS

FIXED MERGER CONSIDERATION DESPITE POTENTIAL CHANGE IN MODTECH STOCK PRICE

      The share exchange ratios and the cash payment price to be paid in the
Modtech Merger and the SPI Merger as described elsewhere in this Joint Proxy
Statement/Prospectus (See "The Mergers -- Merger Consideration") will not be
adjusted despite any increase or decrease in the price of Modtech Common Stock.
The price of Modtech Common Stock when the Mergers occur may vary from its price
at the date of this Joint Proxy Statement/Prospectus and at the date of the
Special Meetings. For example, during the 12-month period ending on September
30, 1998, 1998, the closing price of Modtech Common Stock varied from a low of
$11.625 to a high of $29.750 and ended that period at $17.500. (See "Modtech
Common Stock Prices and Dividends" for further information). Further variations
in the price of Modtech's Common Stock from the date of this Joint Proxy
Statement/Prospectus may be the result of changes in the business or operations
of Modtech or the prospects of its businesses, changes in market assessments of
Modtech or SPI's business, operations, or prospects, or in market assessments of
the effects of the Mergers, or the likelihood they will be consummated, the tax
effects of the Mergers, and the timing thereof, as well as general market and
economic conditions and other factors. At the time of the SPI Special Meeting
and the Modtech Special Meeting, the holders of Modtech and SPI shares will not
know the exact value of the Holdings shares that they will receive when the
Mergers are completed. Modtech and SPI stockholders are urged to obtain current
market quotations for Modtech Common Stock.

INTEGRATION OF OPERATIONS

      For the Mergers to result in the anticipated long-term strategic benefits,
the management of Holdings must integrate the administrative, production,
engineering and accounting functions of the two companies and coordinate their
separate sales and marketing systems in a profitable manner. SPI has not yet
fully integrated the operations of its recent acquisitions, Rosewood
Enterprises, Inc. and Office Master of Texas, Inc. Any difficulties encountered
in integrating the businesses of Modtech and SPI, or in completing the
integration of Rosewood and Office Master, could adversely impact the operations
of one or both companies.

DECREASE IN CASH AND INCREASE IN DEBT

      As of June 30, 1998, Modtech had about $25 million in cash and no
long-term debt. Almost all of Modtech's cash reserves will be used to partially
pay the cash portion of the Merger Consideration to Modtech and SPI
stockholders. Following the Mergers, Modtech's assets, together with the assets
of SPI, will be encumbered by approximately $45 million of new debt. The
proceeds from this debt will be used to pay the balance of the cash portion of
the Merger Consideration, refinance SPI's existing debt, pay transaction
expenses of the Mergers and fund working capital needs. As a result of the
decrease in cash, the debt must be serviced by cash from operations. If current
levels of operations of Modtech or SPI decrease, cash from operations may not be
sufficient to service Holdings' debt.

CHANNELS OF DISTRIBUTION

      Modtech has historically sold most of its products through its direct
sales force, while SPI has historically sold most of its products through its
independent dealer network. There is a conflict between these two channels of
distribution. While SPI does not intend to alter its relationship with its



                                       15
   24

independent dealers, it must be able to assure its dealers that they will not be
displaced by Modtech's internal sales force. The failure to provide such
assurances, or the perception by one or more significant independent dealers
that SPI will rely on Modtech's direct sales force, could adversely affect SPI's
future sales.

CONTROL BY PRINCIPAL STOCKHOLDERS

      Upon completion of the Mergers, the current executive officers and
directors of Modtech and the current executive officers and directors of SPI
will, together, continue to own or have voting control over about 36.2% of the
shares of Holdings Common Stock then outstanding. See "Security Ownership of
Certain Beneficial Owners and Management of Holdings." They will be able to
substantially control the outcome of all matters presented to the stockholders
for approval if they choose to vote together. These matters include election of
directors, mergers, consolidations or the sale of all or substantially all of
the assets of Holdings.

POTENTIAL FOR TAXATION OF MERGER CONSIDERATION

      Neither Modtech nor SPI have asked the Internal Revenue Service ("IRS") to
rule on the tax consequences of the Mergers. Modtech and SPI are relying on the
opinions of their tax lawyers that the Mergers will not be taxable to the
Modtech or SPI stockholders, except for the cash received. A lawyer's tax
opinion is not binding on the IRS. If the IRS disagrees with the tax position
taken by Modtech and SPI, it may assess taxes (plus penalties and interest), in
addition to the taxes described in the opinion of tax counsel. Modtech's and
SPI's position might not be upheld by the courts if challenged by the IRS. See
"The Mergers-- Certain Federal Income Tax Consequences."

DEPENDENCE ON KEY PERSONNEL

      Holdings will be dependent upon its executive officers, Evan M. Gruber,
Patrick Van Den Bossche and Michael G. Rhodes. Although Holdings has employment
agreements with each of these individuals, any of its executive officers can
terminate their employment if they choose to do so. If this occurred, operations
could be disrupted.

SHARES ELIGIBLE FOR FUTURE SALE

      Of the 12,622,158 shares of Holdings Common Stock to be outstanding
immediately following the Mergers, approximately 8,466,676 shares will be held
by "affiliates" as determined under Rule 145 of the Securities Act of 1933. The
exact number of shares held by affiliates will be determined by the elections
the SPI stockholders make in the type of Merger Consideration they wish to
receive. See "The Mergers -- Merger Consideration." Certain affiliates have
executed "lock up" agreements which would restrict their ability to resell
approximately 8,172,676 shares received in the Mergers for a period of 90 days
following the closing of the Mergers. Following the expiration of such 90-day
period, the parties to these lock-up agreements, in addition to any other
affiliates, subject to Rule 145, may immediately resell their shares subject to
the volume limitations of Rule 144. In addition to their Rule 145 resale rights,
Holdings has granted these affiliates "piggyback" registration rights, which
entitle them to have a portion of their shares included in any future registered
offerings Holdings may make. Finally, there will be 1,833,422 shares of Holdings
Common Stock registered for sale upon exercise of stock options granted and to
be granted under the stock option plans Holdings will adopt in connection with
the Mergers.

      Sales of substantial amounts of shares of Holdings Common Stock, or even
the potential for such sales, could lower the market price of the Common Stock
and impair the ability of Holdings to raise capital through the sale of equity
securities.

RISKS RELATED TO MODTECH

LEGISLATION AND SCHOOL FUNDING

      The demand for modular relocatable classrooms in California is affected by
various statutes which, among other things, prescribe the way in which all
school classrooms to be constructed on public lands must be designed and
engineered, the methods by which Modtech's customers, primarily individual
school districts, obtain funding for the construction of new facilities, and the
manner in which available funding is spent. As a result, Modtech's business is
heavily dependent upon the legislative and educational policies and financial
condition of the State of California. Funding for new school construction and
rehabilitation of existing schools by California school districts currently is
provided primarily at the State level, through annual allocations of funds
derived from general revenue sources and statewide bond issues. In addition,
school districts obtain funding for the purchase or lease of school facilities
through the imposition of developers' fees and local bond issuances. The
availability of this funding is subject to financial and political
considerations which vary from district to district. The use of funding provided
by the State is also affected by the legislative policies of the State of
California. For example, existing legislation requires, with certain exceptions,
that 30% of new classroom space added using state funds must be relocatable
structures. Modtech's classroom units qualify as relocatable structures. There
are, however, alternative structures that are less relocatable in nature than
Modtech's classrooms that may also satisfy this legislative requirement.
Shortages of financial resources at either State or local levels, or changes in
the legislative or educational policies of the State of California, could have a
material adverse effect upon Modtech. A bill recently passed the California
Legislature, which, if approved by the voters, will eliminate the requirement
that 30% of all classroom space added using California state funds be
relocatable classrooms. The legislation would replace this provision with a
requirement that, in order for school districts to increase the amount of funds
to be received from developers in excess of the statutory level, school
districts must show that 20% of all classroom space, not just space to be added,
consists of relocatable classrooms.

CYCLICAL INDUSTRY

      Modtech's modular classrooms are purchased predominately by school
districts in California. The ability of California school districts to finance
the acquisition of Modtech's products is largely dependent upon the level of
funding available from the State, which is not tied to demand. Despite a growing
student population, Modtech reported losses from 1991 through 1993 when certain
school districts experienced budget shortfalls.

CONCENTRATION OF CUSTOMERS

      Modtech's sales to date have been limited almost exclusively to customers
in California. Modtech markets and sells its modular classrooms primarily to
California school districts, as well as to the State of California and leasing
companies who lease the classrooms to school districts. During the year ended
December 31, 1997, approximately 98.1% of Modtech's net sales was attributable
to the sale of classrooms, with sales of classrooms to individual school
districts and third party lessors to school districts representing approximately
90.2% of Modtech's net sales, and sales of classrooms to the State of California
accounting for approximately 7.9% of net sales for the year.

PRODUCT SPECIFICATIONS AND REGULATION

      Most of Modtech's contracts require Modtech to build classrooms which meet
certain established state mandated function and manufacturing specifications.
Under such contracts, which are typically fixed-price contracts, Modtech assumes
the liability for



                                       17

   26

correcting, without additional compensation, any deficiencies which cause its
classrooms to fail inspection and certification tests. Modtech relies upon its
experience and expertise to evaluate the potential for such liability and to
price its bids accordingly. In addition, Modtech attempts to minimize the risk
of additional exposure by adopting strict quality control standards and
subjecting its units under construction to extensive testing under the
supervision of inspectors hired by Modtech's customers. To date, Modtech's
operating performance has not been materially impacted by such potential
liability. However, should Modtech incur such liability significantly in excess
of that estimated, its profitability would be adversely affected.

FLUCTUATIONS IN QUARTERLY OPERATING RESULTS; SEASONALITY

      Modtech's quarterly revenue typically has been highest in the second and
third quarters of the year when school districts generally place a large number
of orders for modular classrooms to be delivered in time for the upcoming school
year. Additionally, first and fourth quarter revenues are typically lower due to
a greater number of holidays and days of inclement weather during such periods.

RISKS RELATED TO SPI

ABSENCE OF COMBINED OPERATING HISTORY

      The SPI pro forma combined financial results cover periods during which
Office Master and Rosewood were not under common control or management with SPI
and, therefore, may not be indicative of SPI's future financial or operating
results. The success of SPI will depend on management's ability to complete the
integration of Office Master and Rosewood. The inability of SPI to successfully
integrate Office Master and Rosewood and to coordinate and integrate certain
operational, administrative, and accounting functions and computer systems would
have a material adverse effect on SPI.

RELIANCE ON INDEPENDENT DEALERS

      SPI's products are sold primarily through a network of independent
dealers. SPI has few formal marketing or other agreements with its dealers, and
substantially all of SPI's dealers also market and sell products of other
manufacturers. During the pro forma 12-month period ended December 31, 1997, one
of SPI's dealers, GE Capital Modular Space, accounted for about 48.9% of SPI's
revenues, and another dealer, Williams Scotsman, accounted for about 20.3% of
SPI's revenues. GE Capital Modular Space accounted for about 33.1% of SPI's
revenues during the pro forma six-month period ended June 30, 1998, and Williams
Scotsman accounted for about 30.2% of SPI's revenues during the same period. The
pro forma revenues of SPI include all revenues of SPI, Rosewood and Office
Master for the referenced periods. Product demand from any specific dealer may
fluctuate. Any prolonged downturn in demand from one major dealer, or a
coincidental downturn from a combination of dealers could have a material
adverse effect on SPI. In addition, an adverse change in SPI's relationship with
any of its major dealers, any change in the manner in which any of these dealers
conduct business with SPI, including increased pricing pressures from SPI's
larger dealers, or any exclusive or preferred provider arrangements between
these dealers and any of SPI's competitors, could have a material adverse effect
on SPI.

LOW BARRIERS TO ENTRY

      The barriers to entry into the commercial and light industrial modular
building industry are relatively low, consisting primarily of capital required
to develop manufacturing facilities and the availability of a qualified labor
pool. Manufacturers of other modular buildings, including housing and
classrooms, who possess a skilled work force and manufacturing facilities, could
easily adapt their



                                       18

   27

manufacturing facilities to produce modular structures, and might choose to do
so, during an economic downturn in their industry.

AVAILABILITY OF MANUFACTURING EMPLOYEES

      SPI's assembly line process requires a significant number of manufacturing
employees, many of whom are employed at relatively low wages. In periods of low
unemployment, SPI has experienced difficulty in finding suitable replacements
for its workforce when turnover occurs. Additionally, the remote location of
SPI's Office Master facility in Glen Rose, Texas, may make it difficult to hire
employees at that facility. SPI's inability to hire and retain sufficient
numbers of manufacturing employees at any of its operating facilities could have
a material adverse effect on SPI.

FLUCTUATIONS IN QUARTERLY OPERATING RESULTS; SEASONALITY

      Historically, SPI's quarterly sales in the fourth calendar quarter
(October through December) are lowest, and quarterly sales in the third calendar
quarter (July through September) are highest. Fourth quarter revenues typically
are lower due to customer budget and fiscal constraints and as a result of the
reduction in demand due to adverse weather conditions during such period.

                                   THE MERGERS

GENERAL

      Modtech, Inc., a California corporation ("Modtech"), and SPI Holdings,
Inc., a Colorado corporation ("SPI"), are furnishing this Joint Proxy
Statement/Prospectus to holders of shares of (i) SPI common stock, no par value
("SPI Common Stock"), (ii) SPI Series A-1, A-2, A-3, A-4, A-5, and A-6
Convertible Preferred Stock, no par value ("SPI Preferred Stock" and, together
with the SPI Common Stock, "SPI Capital Stock"), in connection with the
solicitation of proxies by the Board of Directors of SPI (the "SPI Board") for
use at the special meeting of stockholders of SPI to be held on December __,
1998, or any adjournment or postponement thereof (the "SPI Special Meeting"),
and to holders of shares of Modtech Common Stock, no par value ("Modtech Common
Stock"), in connection with the solicitation of proxies by the Board of
Directors of Modtech (the "Modtech Board") for use at the special meeting of
stockholders of Modtech to be held on December __, 1998, or any adjournment or
postponement thereof (the "Modtech Special Meeting" and, together with the SPI
Special Meeting, the "Special Meetings").

      At the Special Meetings, holders of Modtech Common Stock and SPI Capital
Stock will be asked to vote upon proposals to approve and adopt

- -     the Agreement and Plan of Reorganization and Merger, dated as of September
      28, 1998, between Modtech and SPI (the "Merger Agreement"), which
      provides, among other things, that Modtech and SPI will each merge with
      separate subsidiaries of Modtech Holdings, Inc., a Delaware corporation
      ("Holdings");

- -     in the case of the Modtech Special Meeting, the merger of a wholly owned
      subsidiary of Holdings, "Modtech Merger Sub" into Modtech (the "Modtech
      Merger"); and

- -     in the case of the SPI Special Meeting, the merger of another wholly owned
      subsidiary of Holdings, "SPI Merger Sub" into SPI (the "SPI Merger").

The mergers contemplated by the Merger Agreement are referred to herein as the
"Mergers." As a result of the Mergers, Modtech and SPI will each become a
wholly-owned subsidiary of Holdings.

      This Joint Proxy Statement/Prospectus also serves as a prospectus of
Holdings with respect to the shares of its Common Stock, par value $0.01 per
share ("Holdings Common Stock"), and its Series A Preferred Stock, par value
$0.01 per share ("Holdings Series A Preferred Stock") that will be issued to (1)
holders of outstanding shares of Modtech Common Stock upon completion of the
Modtech Merger and (2) holders of outstanding shares of SPI Capital Stock upon
completion of the SPI Merger. See "The Mergers--Merger Consideration."

BACKGROUND OF THE MERGERS

      Following completion of its second public offering of shares of common
stock in November 1997, Modtech has sought to increase its sales of
non-classroom products and to expand outside of the California marketplace. Its
initial goal was to commence operations in Arizona as soon as possible, and, in
January and February 1998, its Chief Executive Officer, Evan M. Gruber, met with
the management of Rosewood Enterprises, Inc., a



                                       20

   29

modular commercial builder located in Phoenix, Arizona, concerning Modtech's
potential acquisition of that company. However, unknown to Modtech at the time,
Rosewood was already in acquisition discussions with SPI. In March 1998, Modtech
completed the purchase of Trac Modular Manufacturing, Inc., a modular commercial
builder located in Glendale, Arizona. SPI closed the acquisition of Rosewood in
April 1998.

      Following SPI's acquisition of Rosewood, Evan Gruber called Patrick Van
Den Bossche, President of SPI, to introduce himself. This led to a meeting on
May 4, 1998 at SPI's facility in Rancho Cucamonga, California. At the meeting,
Mr. Gruber and Mr. Van Den Bossche discussed the modular building industry in
general. Mr. Gruber mentioned the possibility of a merger between the two
companies. Mr. Gruber and Mr. Van Den Bossche discussed operating philosophies
and objectives and the potential strategic benefits to the two companies of a
business combination. They agreed to give additional thought to such a
combination and to meet again in the near future.

      On May 22, 1998, Mr. Gruber and two directors of Modtech, Charles
McGettigan and Myron Wick III, met with Mr. Van Den Bossche and four directors
of SPI, Mark King, Bruce Rogers, Charles Gwirtsman, and Charles Hamilton, in San
Francisco, California, to further discuss a possible business combination. A
number of proposals were considered, but none were seriously pursued. SPI
informed Modtech that SPI intended to proceed with an initial public offering
that had been in preparation since the end of April 1998.

      While SPI continued to pursue a possible public offering, Modtech and SPI
continued to discuss a business combination on a periodic basis through early
July 1998. In the second week of July, SPI was informed by its underwriters that
market conditions were not conducive to the completion of SPI's public offering.
Based on these discussions, SPI and its underwriters decided to postpone its
offering.

      On July 13, 1998, a senior management team from SPI, including two
directors, met with Modtech's senior management, including two directors, at
Modtech's headquarters in Perris, California to further discuss terms of a
potential merger and to initiate SPI's due diligence review of Modtech. The
following day, a senior management team from Modtech traveled to SPI's
headquarters in Rancho Cucamonga, California to commence Modtech's due diligence
review of SPI. Negotiations and due diligence reviews, including on-site visits
of each company's facilities by the other company's management team, continued
through late July 1998.

      On August 11, 1998, SPI's attorneys delivered a draft form of the Merger
Agreement to Modtech and its attorneys. On August 19, 1998, senior management
and certain directors of Modtech and SPI, and the attorneys for SPI and Modtech
met to negotiate certain specific terms of the Merger Agreement. Further
negotiations continued into early September 1998.

      During this period, Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ") was asked by Modtech to advise it in connection with the proposed
transaction and to render a fairness opinion.

      On September 9, 1998, the Modtech Board of Directors and Modtech's
attorneys met and discussed in detail the terms of the proposed business
combination, the exchange ratio and cash consideration to be paid, the reasons
for the transaction, and the due diligence findings by Modtech's management
concerning SPI. Representatives from DLJ participated in a portion of the
meeting by telephone during which Modtech's Board of Directors discussed with
them the fairness of the proposed transaction to the Modtech stockholders.
Modtech's Board authorized senior management to proceed with further
negotiations.

      On September 10, 1998, the SPI Board of Directors and SPI's attorneys met
and discussed in detail the terms of the proposed business



                                       21

   30

combination, the exchange ratio and cash consideration to be paid, the reasons
for the transaction, and the due diligence findings by SPI's management
concerning Modtech. SPI's Board unanimously approved the terms of the Merger
Agreement and Mergers presented to it, subject to final changes to the merger
documentation and completion of the due diligence by management.

      The merger documentation and due diligence were completed in late
September. On September 28, 1998, Modtech's Board of Directors held a special
telephonic meeting to further consider and vote on the proposed transaction.
Representatives of DLJ reviewed with the Board certain financial analyses
relating to the transaction and rendered an oral fairness opinion, which it
confirmed in writing later that day. After considering and discussing the
various presentations at the meeting, and at prior meetings, the Modtech Board
of Directors unanimously approved the Merger Agreement and the Mergers. The
Merger Agreement was signed and delivered that evening by both Modtech and SPI
after the close of business. The signing was publicly announced shortly after
the opening of the securities markets on September 29, 1998.

REASONS FOR THE MERGERS; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

      Modtech and SPI believe that their combination will create value for both
companies' stockholders by providing opportunities to achieve substantial
benefits that would not be available to either company alone. Specifically, the
combination allows for substantial synergy in three identified areas:

- -     Product Diversification. Modtech currently manufactures modular
      relocatable classrooms. SPI makes commercial and light industrial modular
      buildings. The Mergers move Modtech towards accomplishing its goal of a
      decreased dependency on the California Public School System. Additionally,
      the Mergers enhance Modtech's capability for the production of other types
      of modular structures for commercial customers.

- -     Geographic Diversification. At present, Modtech manufactures modular
      relocatable classrooms, of which approximately 98% are sold to California
      public schools. Modtech's strategy for the past few years has been to
      increase its efforts to expand the market for its classrooms to include
      neighboring states. SPI currently does business in California, Arizona,
      Nevada, Colorado Texas, New Mexico and other neighboring states.

- -     Operating Efficiencies. Modtech and SPI plan to consolidate certain of the
      manufacturing and administrative functions of both companies.
      Additionally, efficiencies in purchasing and shipping may be realized due
      to increased levels of production.

      The Boards of Directors of each company also considered various other
factors that contributed to their approval and recommendation of the Merger
Agreement and the Mergers. Those factors include: (1) the terms and conditions
of the Merger Agreement, including an exchange ratio that provides certainty
about the number of shares to be issued and received in the Mergers; and (2) the
expected, although not certain, treatment of the Mergers as tax-free exchanges
of stock, with only the cash received being taxable.

      The SPI Board also considered the advantages of obtaining liquidity for
its stockholders through the merger with Modtech, a publicly-traded company, and
also reducing the risk to its stockholders in the combined company. Immediately
following the Mergers, Holdings will have a lower debt to historical operating
cash flow ratio than SPI had on a stand-alone basis.

      The Modtech Board also considered a number of other items and factors,
including, without limitation, the following:



                                       22

   31

- -     the financial presentation of DLJ to the Modtech Board and that firm's
      opinion that the Modtech Merger Consideration to be received by the
      stockholders of Modtech pursuant to the Merger Agreement is fair to such
      stockholders from a financial point of view;

- -     Modtech's business, management, financial performance and condition,
      strategic objectives, prospects and competitive position, and the
      recommendations of Modtech's management;

- -     a review of strategic alternatives, including other possible business
      combinations and, based on such review, the belief that a transaction with
      another company may not offer terms with advantages comparable to those of
      a business combination with SPI;

- -     the value of the cash component of the Modtech Merger Consideration on a
      per share basis, after adjustments for the number of shares of Holdings
      Common Stock and Holdings Series A Preferred Stock to be received by
      Modtech stockholders in the Modtech Merger;

- -     the ability of the stockholders of Modtech to continue to participate in
      Modtech's business as part of Holdings after the Mergers and to benefit
      from the potential appreciation of Holdings Common Stock;

- -     due diligence review of the financial condition, results of operations and
      business prospects of SPI;

- -     the terms and conditions of the Merger Agreement and the parties'
      respective representations, warranties, covenants, agreements and
      conditions to their respective obligations, including the condition that
      the Mergers be approved by Modtech's stockholders; and

- -     the risk that benefits sought in the Mergers would not be obtained, the
      risk that the Mergers would not be consummated, the fact that, with a
      fixed exchange ratio, the relative values of Modtech and SPI are fixed by
      the parties in advance and would not take into account subsequent changes
      or changed market perceptions, and the effect of the public announcement
      of the Mergers on the trading price of the Modtech Common Stock.

      The Modtech Board also considered the factors set forth in the section
entitled "Certain Risk Factors."

      Each company's Board determined that the potential advantages of the
Mergers far outweighed the disadvantages. Each company's Board concluded that
the Mergers would result in its company's stockholders realizing greater value
than its company could deliver to them alone. Based on the consideration of
these and other relevant matters, each company's Board unanimously determined
that the Merger Agreement and the Mergers are in the best interests of its
company and its company's stockholders.

      The foregoing discussion of the factors considered by each company's Board
is not intended to be exhaustive, but is believed to include all material
factors considered by each company's Board. In reaching its decision to approve
the Merger Agreement and the Mergers, neither company's Board quantified or
assigned any relative weights to the factors considered, or considered any one
factor to be determinative, and individual directors may have given different
weight to different factors.

      THE MODTECH BOARD OF DIRECTORS AND THE SPI BOARD OF DIRECTORS HAVE EACH
UNANIMOUSLY CONCLUDED THAT THE MERGERS ARE IN THE BEST INTERESTS OF THEIR
RESPECTIVE STOCKHOLDERS, AND EACH UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS
VOTE FOR APPROVAL AND ADOPTION OF THE MERGER

AGREEMENT AND THE MERGERS.  SEE "THE MERGERS -- CONFLICTS OF INTERESTS."

FORM OF THE MERGERS

      If the approval of the holders of Modtech Common Stock is obtained and all
other conditions to the Modtech Merger are satisfied or waived, pursuant to the
Modtech Merger Agreement, the Modtech Merger Sub will be merged with and into
Modtech, with Modtech being the surviving corporation after the Modtech Merger
and a wholly owned subsidiary of Holdings. If the approval of the holders of SPI
Capital Stock is obtained and all other conditions to the SPI Merger are
satisfied or waived, pursuant to the SPI Merger Agreement, the SPI Merger Sub
will be merged into SPI, with SPI being the surviving corporation after the SPI
Merger and a wholly owned subsidiary of Holdings. The date on which the closing
of the Mergers occurs is referred to herein as the "Closing Date."

MERGER CONSIDERATION

      SPI.

      Except for the shares owned by SPI or any of its subsidiaries, at the time
when the Mergers are completed by the filing of Certificates of Merger with the
appropriate Secretaries of State (the "Effective Time"), each share of SPI
Capital Stock will be converted into the right to receive 1.8785 shares of
Holdings Common Stock. Each SPI stockholder on the Record Date may elect to
receive $49.4097 per share for up to 5.9176% of the SPI Capital Stock instead of
shares of Holdings Common Stock. If SPI stockholders do not elect to receive a
total of $8,076,133 in cash in place of shares of Holdings Common Stock, those
SPI stockholders who have elected to receive cash for some of their SPI Capital
Stock, including those who have elected to receive cash for the maximum 5.9176%
of their SPI Capital Stock, will have all or a portion of their remaining SPI
Capital Stock converted into cash until the cash being paid for SPI Capital
Stock equals $8,076,133. The conversion will be pro rata among such stockholders
electing to receive cash based on the shares of SPI Capital Stock held by them
that they did not voluntarily elect to convert to cash. If all such shares are
converted to cash and the total cash being paid still does not equal $8,076,133,
then all SPI stockholders who did not elect to have any of their shares
converted to cash will have their shares converted to cash pro rata based on the
number of shares held by each of them until the total cash being paid for shares
of SPI Capital Stock equals $8,076,133.

      Any shares of SPI Capital Stock owned by SPI, or any of its subsidiaries,
will automatically be cancelled and retired at the Effective Time and will cease
to exist, and no Holdings Common Stock or other consideration will be delivered
in exchange therefor.

      MODTECH.

      Except for shares owned by Modtech or any of its subsidiaries, at the
Effective Time, without any action on the part of any Modtech stockholder, each
issued and outstanding share of Modtech Common Stock will be converted into the
right to receive $3.7293 and 0.8508 shares of Holdings Common Stock. Each
Modtech stockholder as of the Record Date may elect to receive, in place of
Holdings Common Stock, 0.8508 shares of Holdings Series A Preferred Stock for
each share of Modtech Common Stock in an amount up to 3.94% of their shares of
Modtech Common Stock. If Modtech stockholders do not elect to receive a total of
388,939 shares of Holdings Series A Preferred Stock in place of Holdings Common
Stock, two major Modtech stockholders, Lagunitas Partners and Proactive
Partners, L.P. will be allocated shares of Holdings Series A Preferred Stock pro
rata based on their total shares of Modtech Common Stock, until the total number
of shares of Holdings Series A Preferred Stock to be received by Modtech
stockholders in the Modtech Merger equals 388,939. The number of shares of
Holdings Series A Preferred Stock to be



                                       24

   33

received by Modtech stockholders will be adjusted upward or downward to the
extent necessary to comply with the minimum requirements of Section 351 of the
Internal Revenue Code.

      Any shares of Modtech Common Stock owned by Modtech or any of its
subsidiaries will automatically be cancelled and retired at the Effective Time
and will cease to exist, and no Holdings Common or Preferred Stock or other
consideration will be delivered in exchange therefor.

OPINION OF MODTECH'S FINANCIAL ADVISOR

      On September 28, 1998, Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ") rendered an oral opinion to the Modtech Board to the effect that, as of
such date and based upon the qualifications and assumptions made and matters
considered by DLJ described in its written opinion dated September 28, 1998 (the
"Fairness Opinion"), the Merger Consideration to be received in the Mergers by
holders of shares of Modtech Common Stock pursuant to the Merger Agreement is
fair from a financial point of view to such holders.

      THE FULL TEXT OF THE FAIRNESS OPINION IS ATTACHED HERETO AS ANNEX II. THE
SUMMARY OF THE FAIRNESS OPINION SET FORTH IN THIS JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED BY REFERENCE TO THE FULL TEXT OF THE FAIRNESS
OPINION. MODTECH STOCKHOLDERS ARE URGED TO READ THE FAIRNESS OPINION CAREFULLY
AND IN ITS ENTIRETY FOR THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, OTHER MATTERS
CONSIDERED AND LIMITS OF THE REVIEW BY DLJ IN CONNECTION WITH SUCH FAIRNESS
OPINION.

      The Fairness Opinion was prepared for the Modtech Board of Directors and
was directed only to the fairness from a financial point of view, as of the date
thereof, of the consideration to be received by the holders of Modtech Common
Stock pursuant to the Merger Agreement. DLJ expressed no opinion in the Fairness
Opinion as to the prices at which Holdings Common Stock or Holdings Series A
Preferred Stock would actually trade at any time. DLJ was not asked to opine as
to the underlying business decision of the Modtech Board to proceed with the
Mergers, and the Fairness Opinion does not address this decision. The Fairness
Opinion does not constitute a recommendation to any stockholder as to how such
stockholder should vote on the Mergers.

      As part of its investment banking business, DLJ is regularly engaged in
the valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
The Modtech Board was informed that DLJ had previously advised SPI and certain
of its stockholders with respect to possible transactions with Modtech and other
financing alternatives.

      In arriving at the Fairness Opinion, DLJ reviewed the Merger Agreement and
certain exhibits thereto. DLJ also reviewed financial and other information that
was publicly available or furnished to DLJ by Modtech and SPI, including
information provided during discussions with their respective managements.
Included in the information provided during such discussions were certain
financial projections of Modtech prepared by the management of Modtech and
certain financial projections of SPI prepared by the management of SPI. In
addition, DLJ compared certain financial and/or securities data of Modtech and
SPI with publicly available information concerning various companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of Modtech Common Stock, reviewed prices and premiums paid
in certain other business combinations and conducted such other financial
studies, such as discounted cash flow analysis and contribution analysis, and
investigations as DLJ deemed appropriate for purposes of rendering the Fairness
Opinion.



                                       25

   34

      In rendering the Fairness Opinion, DLJ relied upon and assumed the
accuracy and completeness of all of the financial and other information that was
available to it from public sources, that was provided to it by Modtech or SPI
or their respective representatives, or that was otherwise reviewed by DLJ. With
respect to the financial projections supplied to DLJ, DLJ assumed that they were
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the managements of Modtech and SPI as to the future operating
and financial performance of Modtech and SPI, respectively. DLJ did not assume
responsibility for making any independent evaluation of the assets or
liabilities of Modtech or SPI, or for making any independent verification of the
information reviewed by DLJ. DLJ also assumed that the cash portion of the
consideration to be received by the holders of Modtech Common Stock would not
otherwise be received by such holders in the ordinary course of business.

      The Fairness Opinion was necessarily based on economic, market, financial
and other conditions as they existed on, and on the information made available
to DLJ as of, the date of the Fairness Opinion. The Fairness Opinion was based,
in part, on publicly available information as of September 23, 1998. Although
subsequent developments may affect its Fairness Opinion, DLJ does not have any
obligation to update, revise or reaffirm its opinion.

      The following is a summary of the presentation made by DLJ to the Modtech
Board of Directors at its September 28, 1998 meeting, in connection with
rendering the Fairness Opinion.

      Stock Price History. To provide contextual data and comparative market
data, DLJ reviewed the daily closing prices for the 12-month period ending
September 22, 1998 of Modtech Common Stock and compared such closing stock
prices with the closing stock prices of two publicly traded modular building
companies, Butler Manufacturing Company and Miller Building Systems, Inc. and
the Russell 2000 Index. The two modular building companies were the only two
directly comparable companies identified by DLJ which were publicly traded. This
information was presented solely to provide the Modtech Board with background
information regarding the stock prices of Modtech Common Stock relative to its
peers and an appropriate index.

      Comparable Publicly Traded Company Analysis. DLJ believed that this form
of analysis was not meaningful because of an insufficient number of publicly
traded companies in the modular building industry.

      Comparable Merger & Acquisition Transaction Analysis. DLJ believed that
this form of analysis was not meaningful because of an insufficient number of
recent merger and acquisition transactions in the modular building industry.

      Earnings Per Share Impact. DLJ analyzed the earnings per share impact of
the Mergers to holders of Modtech Common Stock. For the latest 12-month period
ending June 30, 1998, and the projected fiscal years ending December 1998, 1999
and 2000, the Mergers resulted in accretion (dilution) of (22.7%) or ($0.36) per
share, (11.3%) or ($0.18) per share, 4.3% or $0.08 per share and 4.5% or $0.10
per share, respectively. In arriving at these accretion (dilution) results, DLJ
compared Holdings' pro forma earnings per share estimates with First Call's
estimates of Modtech's earnings per share, and assumed the Mergers would not
result in any synergies.

      Comparable Premiums Paid Analysis. DLJ determined the implied premium over
the common stock trading prices for one day, one week and four weeks prior to
the announcement date of 293 selected domestic merger or acquisition
transactions involving companies not necessarily comparable to Modtech, ranging
from $200 million to $400 million in transaction value and completed from
January 1995 through September 17, 1998. The average premiums for the selected
transactions over the common stock trading prices for : (i) one day prior to the



                                       26

   35

announcement date was 29.0%; (ii) one week prior to the announcement date was
33.1%; and (iii) four weeks prior to the announcement date was 44.3%. Applying
the above average comparable premiums to the closing price of the Modtech Common
Stock on one day, one week and four weeks prior to September 22, 1998 implies a
valuation per share of Modtech Common Stock of $25.32, $23.79 and $27.96,
respectively, as compared to the closing prices of the Modtech Common Stock one
day, one week and four weeks prior to September 22, 1998 of $19.63, $17.88 and
$19.38, respectively.

      Contribution Analysis. DLJ analyzed the relative contributions of Modtech
and SPI to the pro forma combined entity based on selected financial data,
assuming no synergies. In this analysis, DLJ compared the 65.6% fully diluted
ownership interest that holders of Modtech Common Stock will have in the pro
forma combined entity with the relative contribution of Modtech to certain
financial data for the pro forma combined entity, including revenue, earnings
before interest, taxes, depreciation and amortization ("EBITDA") and earnings
before interest and taxes ("EBIT") for the fiscal years ending December 31, 1998
("Fiscal Year 1998") and December 31, 1999 ("Fiscal Year 1999"). In each case,
the financial data for the pro forma combined entity was determined by adding
the financial data for Modtech and SPI. This analysis indicated that Modtech
would contribute: (i) 64.5% and 64.9% of the pro forma combined entity's sales
for Fiscal Year 1998 and Fiscal Year 1999, respectively; (ii) 69.5% and 67.9% of
the pro forma combined entity's EBITDA for Fiscal Year 1998 and Fiscal Year
1999, respectively; and (iii) 71.4% and 68.9% of the pro forma combined entity's
EBIT for Fiscal Year 1998 and Fiscal Year 1999, respectively.

      DLJ also compared the 65.6% ownership interest that holders of Modtech
Common Stock will have in the pro forma combined entity with the relative
contribution of Modtech to the estimated net income of the pro forma combined
entity (determined by adding the net income of Modtech and SPI for Fiscal Year
1998 and Fiscal Year 1999). This analysis indicated that Modtech would
contribute 73.5% and 70.2% of the net income of the pro forma combined entity
for Fiscal Year 1998 and Fiscal Year 1999, respectively.

      Discounted Cash Flow Analysis. DLJ performed a discounted cash flow
analysis (i.e., an analysis of the present value of projected cash flows using
the discount rates and terminal year EBITDA multiples indicated below) of
Modtech, SPI and Holdings using projections and assumptions provided by the
management of Modtech. The discounted cash flow for all three entities was
estimated using discount rates ranging from 9% to 12% and terminal multiples of
estimated EBITDA for each entity's fiscal year ending December 31, 2003 ranging
from 6.0x to 8.0x. This analysis assumed no synergies and yielded an implied
common equity value range for Holdings of $28.70 to $32.29 per fully diluted
share of Holdings, and an implied equity value range per share (including the
cash distribution) for Modtech of $28.16 to $31.22 as compared to the price of
September 23, 1998 of $20.50.

      The summary set forth above does not purport to be a complete description
of the analyses performed by DLJ but describes, in summary form, the material
elements of the presentations made by DLJ to the Modtech Board of Directors on
September 28, 1998. The preparation of a fairness opinion involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to summary
description. Each of the analyses conducted by DLJ was carried out in order to
provide a different perspective on the transaction and to add to the total mix
of information available. DLJ did not form a conclusion as to whether any
individual analysis, considered in isolation, supported or failed to support an
opinion as to fairness from a financial point of view. Rather, in reaching its
conclusion, DLJ considered the results of the analyses in light of each other
and ultimately



                                       27

   36

reached its opinion based on the results of all analyses taken as a whole.
Accordingly, notwithstanding the separate factors summarized above, DLJ has
indicated to Modtech that it believes that its analyses must be considered as a
whole and that selecting portions of its analyses and the factors considered by
it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying its opinion. The analyses performed by
DLJ are not necessarily indicative of actual values or future results, which may
be significantly more or less favorable than suggested by such analyses.

      Pursuant to the terms of an engagement agreement dated September 25, 1998,
Modtech agreed to pay DLJ a fee of $750,000, irrespective of the conclusion
reached therein. In addition, Modtech has agreed to reimburse DLJ promptly for
all out-of-pocket expenses (including the reasonable fees and expenses of
counsel) incurred by DLJ in connection with the Fairness Opinion and to
indemnify DLJ and certain related persons against certain liabilities in
connection with its engagement, including liabilities under U.S. federal
securities laws.

      In the ordinary course of business, DLJ and its affiliates may own or
actively trade the securities of Modtech for their own accounts and for the
accounts of their customers and, accordingly, may at any time hold a long or
short position in Modtech securities.

PROCEDURES FOR ELECTION OF MERGER CONSIDERATION AND SURRENDER OF STOCK
CERTIFICATES; FRACTIONAL SHARES

      SPI. In order to receive the SPI Merger Consideration (See "The Mergers --
Merger Consideration -- SPI"), SPI stockholders must surrender to ChaseMellon,
the Exchange Agent, whose address is 400 South Hope Street, 4th Floor, Los
Angeles, California 90071, the certificate or certificates for their shares of
SPI Capital Stock. As soon as feasible, after the Effective Time, the Exchange
Agent will send to each SPI stockholder a letter of transmittal and instructions
for use in surrendering their certificates and making an election to receive
cash at $49.4097 per share in place of Holdings Common Stock for up to 5.9176%
of their shares, if they so desire. The method of making adjustments to
stockholder elections as described above (See "The Mergers -- Merger
Consideration -- SPI") will be set forth in the letter of transmittal. Any
necessary adjustments to stockholder elections will be made by the Exchange
Agent.

      SPI stockholders will not receive any fractional shares of Holdings Common
Stock. Instead, they will be paid cash equal to the closing price of a share of
Modtech Common Stock on the Nasdaq National Market on the last business day
prior to the closing of the Mergers, multiplied by the fraction of a share they
otherwise would have received.

      After the Effective Time, there will be no further transfer on the records
of SPI or its transfer agent of certificates representing shares of SPI Capital
Stock, and, if such certificates are presented to SPI for transfer, they will be
cancelled against delivery of the SPI Merger Consideration pursuant to the
Merger Agreement. Until surrendered in accordance with the Merger Agreement,
each certificate for shares of SPI Capital Stock will be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the SPI Merger Consideration pursuant to the Merger Agreement. No
interest will be paid or will accrue on any cash payable as consideration in the
Mergers or in lieu of any fractional shares of Holdings Common Stock.


HOLDERS OF SPI CAPITAL STOCK SHOULD NOT SEND ANY OF THEIR STOCK CERTIFICATES TO
SPI OR THE EXCHANGE AGENT AT THIS TIME.

      Modtech. In order to receive the Modtech Merger Consideration, Modtech
stockholders must surrender to ChaseMellon, the Exchange Agent, whose address is
400 South Hope Street, 4th Floor,



                                       28

   37

Los Angeles, California 90071, the certificate or certificates, representing
their shares of Modtech Common Stock. As soon as feasible after the Effective
Time, the Exchange Agent will send to each Modtech stockholder a letter of
transmittal and instructions for use in surrendering their certificates and
making an election to receive Holdings Series A Preferred Stock for up to 3.94%
of their Modtech Common Stock. NO MODTECH STOCKHOLDER IS REQUIRED TO ELECT TO
RECEIVE HOLDINGS SERIES A PREFERRED STOCK, SINCE TWO MAJOR MODTECH STOCKHOLDERS,
LAGUNITAS PARTNERS AND PROACTIVE PARTNERS, L.P., HAVE AGREED TO ACCEPT ALL THE
SHARES OF HOLDINGS SERIES A PREFERRED STOCK TO BE ISSUED IN THE MODTECH MERGER.
The method of making adjustments to stockholder elections and the amount of
Holdings Series A Preferred Stock to be allocated as described above (See, "The
Mergers -- Merger Consideration -- Modtech") will be set forth in the letter of
transmittal. Any necessary adjustments to stockholder elections or the number of
shares of Holdings Series A Preferred Stock to be allocated will be made by the
Exchange Agent.

      Modtech stockholders will not receive any fractional shares of Holdings
Common Stock or Holdings Series A Preferred Stock. Instead, they will be paid
cash equal to the closing price of a share of Modtech Common Stock on the Nasdaq
National Market on the last trading day prior to the closing of the Mergers
multiplied by the fraction of a share of Holdings Common Stock they otherwise
would have received. Shares of Holdings Series A Preferred Stock will be rounded
upward to the nearest whole number of shares.

      After the Effective Time of the Merger, there will be no further transfer
on the records of Modtech or its transfer agent of certificates representing
shares of Modtech Common Stock, and, if such certificates are presented to
Modtech for transfer, they will be cancelled against delivery of the Modtech
Merger Consideration pursuant to the Merger Agreement. Until surrendered in
accordance with the Merger Agreement, each certificate for shares of Modtech
Common Stock will be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the Modtech Merger Consideration
pursuant to the Merger Agreement. No interest will be paid or will accrue on any
cash payable as consideration in the Mergers or in lieu of any fractional shares
of Holdings Common Stock.


HOLDERS OF MODTECH COMMON STOCK SHOULD NOT SEND ANY OF THEIR STOCK CERTIFICATES
TO MODTECH OR THE EXCHANGE AGENT AT THIS TIME.

EFFECTIVE TIME

      On the Closing Date, the parties will file certificates of merger or other
appropriate documents (in any such case, the "Certificates of Merger") and will
make all other filings or recordings required under the Delaware General
Corporation Law ("DGCL"), the California General Corporation Law and the
Colorado Business Corporation Act. The Mergers will become effective at such
time as the Certificate of Mergers are duly filed with the Secretary of State of
the State of Delaware, or at such later time as Modtech and SPI specify in the
Certificates of Merger (the time the Mergers become effective being the
"Effective Time"). Such filing will be made as promptly as practicable after
satisfaction or waiver of the conditions to the Mergers set forth in the Merger
Agreement.

EFFECT ON SPI STOCK PLAN

      The Merger Agreement provides that, as a result of the Mergers, the
vesting of all options outstanding under SPI's Second Amended and Restated 1997
Stock Option Plan ("SPI Options") that are not then at least 75% vested will be
accelerated pro rata based on the unvested portion of such options until all SPI
Options are in the aggregate 75% vested. An option is considered 75% vested if
the number of shares purchased under any prior exercise of the option, plus the
number of shares the option is exercisable for immediately prior to the
completion of the


                                       29
   38

Mergers, equals 75% of the total number of shares covered by the original grant
of the option. 5.9176% of the shares covered by the vested portion of each SPI
Option will be converted into the right to receive $49.4097 per share in cash,
less the applicable per share exercise price of each SPI Option. Each remaining
SPI Option will be converted into and become a right to acquire 1.8785 shares of
Holdings Common Stock for each share of SPI Common Stock previously covered by
the converted SPI Option.

EFFECT ON SPI WARRANTS

      The Merger Agreement provides that all outstanding warrants to purchase
SPI Common Stock ("SPI Warrants") will be deemed exercised immediately prior to
the Effective Time. At the Effective Time, 5.9176% of the SPI Warrants held by
each warrant holder will be converted into the right to receive $49.4097 per
share in cash, less the applicable exercise price of the SPI Warrants. Each
remaining SPI Warrant will be converted into the right to receive 1.8785 shares
of Holdings Common Stock upon payment of the adjusted warrant exercise price.

EFFECT ON MODTECH STOCK PLANS

      The Merger Agreement provides that, as a result of the Mergers, all
outstanding options to purchase Modtech Common Stock ("Modtech Options") that
are not then at least 75% vested will be accelerated pro rata based on the
unvested portion of such options until all Modtech Options are in the aggregate
75% vested. An option is considered 75% vested if the number of shares purchased
under any prior exercise of the option, plus the number of shares the option is
exercisable for immediately prior to the completion of the Mergers, equals 75%
of the total number of shares covered by the original grant of the option.
14.6709% of the shares covered by the vested portion of each Modtech Option will
be converted into the right to receive $25.00 per share in cash, less the
applicable per share exercise price. Each remaining Modtech Option will be
converted into and become a right to acquire 0.8508 shares of Holdings Common
Stock for each share of Modtech Common Stock previously covered by the converted
Modtech Option.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

      The following is a summary of the material United States federal income
tax considerations generally applicable to holders of Modtech Common Stock and
holders of SPI Capital Stock who, pursuant to the Mergers, exchange such stock
holdings for the Merger Consideration. Consummation of the Modtech Merger is
conditioned upon the receipt by Modtech of an opinion of Gibson, Dunn & Crutcher
LLP, special tax counsel to Modtech, based upon requested representation letters
and dated the Closing Date, to the effect that the Modtech Merger will qualify
as an exchange governed by Section 351 of the Internal Revenue Code of 1986, as
amended (the "Internal Revenue Code"). Consummation of the SPI Merger is
conditioned upon the receipt by SPI of an opinion of Dorsey & Whitney LLP,
counsel to SPI, based upon requested representation letters and dated the
Closing Date, to the effect that the SPI Merger will qualify as a reorganization
under Section 368 of the Internal Revenue Code. The summary below assumes that
the Modtech Merger and the SPI Merger will be treated for United States federal
income tax purposes in accordance with those opinions.

      This summary is based upon the current provisions of the Internal Revenue
Code, currently applicable Treasury regulations thereunder, judicial decisions,
and current administrative decisions and rulings. There can be no assurance that
the Internal Revenue Service ("IRS") will not take a contrary view, and no
ruling from the IRS has been or will be sought regarding tax treatment of the
Modtech Merger and the SPI Merger. Future legislative, judicial or
administrative changes or interpretations could alter or modify the statements
and conclusions set forth in this summary, and any such change or



                                       30

   39

interpretations could be retroactive and could affect the tax consequences to
the stockholders of Modtech and SPI.

      The following summary does not address all aspects of federal income
taxation that may be important to particular stockholders in light of their
personal investment circumstances or to stockholders subject to special
treatment under the federal income tax laws (including life insurance companies,
foreign persons, tax-exempt entities, and holders who acquired their Modtech
Common Stock or SPI Capital Stock pursuant to the exercise of employee stock
options or otherwise as compensation) and does not address any aspect of state,
local or foreign taxation. This summary also assumes that the Modtech Common
Stock and the SPI Capital Stock will be held as capital assets on the Closing
Date.

      Treatment of Holders of Modtech Common Stock. Except as discussed below
under "Cash in Lieu of Fractional Shares," a holder of Modtech Common Stock will
recognize gain realized in the transaction but will not recognize any loss
realized in the transaction. The amount of gain that is recognized will be equal
to the lesser of (i) the amount of gain realized in the transaction (i.e., the
excess of (a) the sum of the amount of cash and the fair market value of
Holdings Common Stock and Holdings Series A Preferred Stock received over (b)
the tax basis of the Modtech Common Stock relinquished) and (ii) the amount of
cash received. The amount of such recognized gain will be subject to federal
income tax at capital gain rates or ordinary income rates depending upon whether
the receipt of cash is viewed as a redemption of stock or as a dividend
distribution under the rules discussed below.

      Because the Modtech stockholders will, as a group, possess more than 50%
of the total value of shares of all classes of stock of Holdings following the
Mergers, the treatment of any gain recognized by a Modtech stockholder as
capital gain or as dividend income must be determined by applying the rules of
Section 302 of the Internal Revenue Code. As to each Modtech stockholder, this
is determined by viewing Holdings as redeeming a portion of a Modtech
stockholder's Modtech Common Stock for the amount of cash received by such
stockholder in the Modtech Merger. To determine whether the redemption is
treated as a dividend distribution or as a redemption of the stockholder's
Modtech Common Stock, a Modtech stockholder must compare his or her
proportionate, percentage interest in Modtech prior to the Modtech Merger with
such stockholder's indirect proportionate, percentage interest in Modtech after
the Modtech Merger by reason of such stockholder's direct ownership of Holdings
Common Stock and Holdings Series A Preferred Stock. Such comparison should take
into account the Holdings Common Stock issued to the SPI stockholders in the SPI
Merger.

      The cash distribution received by a Modtech stockholder will be treated as
a redemption of such stockholder's stock rather than a dividend if, under the
redemption tests of Section 302 of the Internal Revenue Code, such distribution
(i) is "not essentially equivalent to a dividend" with respect to the
stockholder, or (ii) results in a "substantially disproportionate" redemption of
such stockholder's equity interest in Modtech (the "Section 302 Tests").

      A redemption will be "substantially disproportionate" if (i) after the
redemption the stockholder owns less than 50% of the total combined voting power
of all classes of stock of Modtech entitled to vote, and (ii) the percentage
ownership of Modtech "common stock" and "voting stock" immediately after the
redemption is less than 80% of the stockholder's percentage ownership in such
stock immediately before the redemption. If the redemption from a Modtech
stockholder fails to satisfy the "substantially disproportionate" test, such
stockholder may nonetheless satisfy the "not essentially equivalent to a
dividend" test.

      Under the principles established in United States v. Davis, 397 U.S. 301
(1970), a distribution to a



                                       31

   40

Modtech stockholder will not be "essentially equivalent to a dividend" if it
results in a "meaningful reduction" in such stockholder's proportionate stock
interest in Modtech. If a stockholder with a relatively minimal stock interest
in Modtech and no exercise of control over corporate affairs suffers a reduction
in his proportionate interest in Modtech as a result of the redemption, that
stockholder should be regarded as having suffered a meaningful reduction of his
or her interest in Modtech. For example, the IRS has held in a published ruling
that in the case of a less than 1% stockholder who does not have management
control over the corporation, any reduction in proportionate interest will
constitute a "meaningful reduction."

      In applying the Section 302 Tests, the constructive stock ownership rules
of Internal Revenue Code Section 318 apply and require that each Modtech
stockholder take into account not only the Modtech Common Stock directly owned
by the stockholder, but also Modtech Common Stock owned by certain of the
stockholder's family members, stock owned by partnerships, trusts, corporations
and other entities in which the stockholder has an interest, as well as Modtech
Common Stock the stockholder has a right or option to acquire.

      If none of the redemption tests under Section 302 of the Internal Revenue
Code is satisfied, the cash received by a Modtech stockholder will be treated as
a dividend to the extent of such stockholder's allocable portion of the earnings
and profits (as determined for federal income tax purposes) of Modtech and
Holdings. If the amount of cash exceeds a Modtech stockholder's allocable
portion of earnings and profits, the excess will be treated first as a return of
capital to the extent of such stockholder's tax basis in his or her shares and
then as capital gain.

      Because the determination of whether cash received in the Modtech Merger
will be treated as the distribution of a dividend generally will depend upon the
particular facts and circumstances of each Modtech stockholder, each Modtech
stockholder is strongly advised to consult their own tax advisor regarding the
tax treatment of cash received pursuant to the Modtech Merger.

      Treatment of Holders of SPI Capital Stock. Except as discussed below under
"Cash in Lieu of Fractional Shares," a holder of SPI Capital Stock that only
receives Holdings Common Stock will not recognize gain or loss. A holder of SPI
Capital Stock that receives a combination of Holdings Common Stock and cash will
recognize gain realized in the transaction but will not recognize any loss
realized in the transaction. The amount of gain that is recognized will be
calculated separately for each block of SPI Capital Stock, in an amount equal to
the lesser of (i) the amount of gain realized with respect to such block (i.e.,
the excess of (a) the sum of the amount of cash and the fair market value of
Holdings Common Stock received that is allocable to such block over (b) the tax
basis of the block of SPI Capital Stock relinquished) and (ii) the amount of
cash received that is allocable to such block. The amount of such recognized
gain will be subject to federal income tax at capital gain rates or ordinary
income rates depending upon whether the receipt of cash is viewed as a
redemption of stock or as a dividend distribution under the rules discussed
below.

      The determination of whether the exchange of SPI Capital Stock for cash
pursuant to the SPI Merger has the effect of a distribution of a dividend will
be made by applying the Section 302 Tests that are described above under
"Treatment of Holders of Modtech Common Stock," and by also taking into account
any shares of Holdings Common Stock considered to be owned by such SPI
stockholder by reason of the constructive ownership rules of Internal Revenue
Code Section 318 that are also described above under "Treatment of Holders of
Modtech Common Stock."

      Pursuant to the principles established in Clark v. Commissioner, 489 U.S.
726 (1989), the Section 302



                                       32

   41

Tests are applied to an SPI stockholder by comparing the proportionate,
percentage interest of an SPI stockholder in Holdings after the SPI Merger with
the proportionate, percentage interest in Holdings such stockholder would have
had if such stockholder had received solely Holdings Common Stock in the SPI
Merger. This comparison is made as though Holdings had issued solely Holdings
Common Stock to such stockholder in the SPI Merger and in a hypothetical
redemption Holdings had then redeemed a portion of its Holdings Common Stock for
the amount of cash the stockholder actually received in the SPI Merger. In
making this comparison, it is likely that the effect of the Modtech Merger would
be taken into account as though Holdings had issued solely Holdings Common Stock
in the Modtech Merger and in a hypothetical redemption Holdings had then
redeemed a portion of its Holdings Common Stock for the amount of cash received
by the Modtech stockholders.

      If receipt of cash by an SPI stockholder has the effect of a distribution
of a dividend, the gain recognized will be treated as a dividend to the extent
of the stockholder's ratable share of SPI's undistributed earnings and profits,
as determined for federal income tax purposes. If the amount of cash exceeds an
SPI stockholder's ratable share of earnings and profits, the excess will be
treated first as a return of capital to the extent of such stockholder's tax
basis in his or her shares and then as capital gain. Any gain that does not have
the effect of a distribution of a dividend will be a capital gain.

      Because the determination of whether cash received in the SPI Merger will
be treated as the distribution of a dividend generally will depend upon the
particular facts and circumstances of each SPI stockholder, each SPI stockholder
is strongly advised to consult their own tax advisor regarding the tax treatment
of cash received pursuant to the SPI Merger.

      The Merger Agreement provides that, subject to the limits therein, each
SPI stockholder may elect which of such stockholder's SPI Capital Stock, if any,
will be exchanged for cash in the SPI Merger. In the event the receipt of cash
by an SPI stockholder is not treated as a dividend, as explained above, the tax
treatment of the cash may be different depending on which shares of SPI Capital
Stock are deemed to be exchanged for cash and which shares are deemed to be
exchanged for Holdings Common Stock. While there is some authority suggesting
that a stockholder's allocation of stock and cash to certain shares of SPI
Capital Stock should be respected, there can be no assurance that the IRS will
not take a contrary position. Because of the absence of definitive authority,
SPI stockholders are strongly advised to consult with their own tax advisors.

      Basis and Holding Period of the Holdings Common Stock and Holdings Series
A Preferred Stock. The basis of the Holdings Common Stock (including any
fractional shares for which cash is received described below) received by a
Modtech stockholder or an SPI stockholder in the Mergers will equal the basis of
the Modtech Common Stock or SPI Capital Stock surrendered by such stockholder in
the respective Merger, decreased by the amount of cash received by such
stockholder, and increased by the amount of capital gain recognized by such
stockholder and the amount treated as a dividend to such stockholder. As to any
Modtech stockholder that receives both Holdings Common Stock and Holdings Series
A Preferred Stock, such basis amount shall be allocated to each class of stock
based upon the relative fair market value of each class. As to SPI stockholders,
the basis of the Holdings Common Stock received in the SPI Merger will be
determined separately with respect to each block of SPI Capital Stock
surrendered in the SPI Merger.

      The holding period of the Holdings Common Stock and the Holdings Series A
Preferred Stock will include the period during which the Modtech Common Stock or
SPI Capital Stock surrendered in the Mergers was held.



                                       33

   42

      Cash in Lieu of Fractional Shares. Cash received by a Modtech stockholder
or SPI stockholder in lieu of a fractional share interest of Holdings Common
Stock will be treated as having been received as a distribution in full payment
in exchange for the fractional share interest in Holdings Common Stock which
such stockholder would otherwise be entitled to receive, and will qualify as
capital gain or loss, or as a dividend under the Section 302 Tests discussed
above.

      Conversion of Holdings Series A Preferred Stock. A holder of Holdings
Series A Preferred Stock will not recognize income, gain or loss upon the
conversion of such stock into Holdings Common Stock. A holder's basis in the
Holdings Common Stock received upon conversion will equal the basis of the
Holdings Series A Preferred Stock so converted, and the holding period of the
Holdings Common Stock received upon conversion will include the holding period
of the Holdings Series A Preferred Stock so converted.

      Reporting Requirements and Backup Withholding. Each Modtech stockholder
and SPI stockholder will be required to retain records and file with such
holder's United States federal income tax return a statement setting forth
certain facts relating to the Modtech Merger and the SPI Merger.

      Backup withholding at the rate of 31% may apply with respect to certain
payments unless the recipient (i) is a corporation or comes within certain other
exempt categories and, when required, demonstrates this fact or (ii) provides a
correct taxpayer identification number, certifies as to no loss of exemption
from backup withholding and otherwise complies with applicable requirements of
the backup withholding rules. A stockholder who does not provide Holdings with
its correct taxpayer identification number may be subject to penalties imposed
by the IRS. Any amounts withheld under the backup withholding rules may be
allowed as a refund or credit against the stockholder's federal income tax
liability, provided that certain required information is furnished to the IRS.

      Holdings will report to stockholders of Holdings and to the IRS the amount
of "reportable payments" and any amount withheld with respect to Holdings Common
Stock and Holdings Series A Preferred Stock during each calendar year.

      THIS FEDERAL INCOME TAX DISCUSSION IS FOR GENERAL INFORMATION ONLY AND MAY
NOT APPLY TO ALL HOLDERS OF MODTECH COMMON STOCK OR ALL HOLDERS OF SPI CAPITAL
STOCK. SUCH HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES OF THE MERGERS.

CONFLICTS OF INTEREST

      In considering the respective recommendations of the Modtech Board and the
SPI Board with respect to the Mergers, stockholders of Modtech and SPI should be
aware that, as described below, certain members of SPI's and Modtech's
management and Boards may have interests in the Mergers that are different from,
or in addition to, the interests of stockholders of Modtech and SPI, and that
may create potential conflicts of interest. The Modtech Board and the SPI Board
have each considered these interests, among other matters, in approving and
adopting the Merger Agreement and the Mergers.

      Holdings Board of Directors. Four of the eight current directors of
Modtech, Evan M. Gruber, Charles C. McGettigan, Myron A. Wick III and Daniel J.
Donahoe III, will become directors of Holdings. Three of the six current
directors of SPI, Patrick Van Den Bossche, Charles A. Hamilton and Charles R.
Gwirtsman, will become directors of Holdings.

      Holdings Executive Officers. Evan M. Gruber, Chief Executive Officer of
Modtech, Patrick Van Den Bossche, President of SPI, and Michael G. Rhodes, Chief
Operating Officer and Chief Financial Officer of Modtech, will each hold the
same



                                       34

   43

positions with Holdings as they presently hold with SPI or Modtech. In
connection with the Merger Agreement, Holdings will enter into employment
agreements with these officers. See "Directors and Executive Officers of
Holdings Following the Mergers -- Compensation of Executive Officers."

      Transaction Fees. KRG Capital Partners, LLC ("KRG"), Infrastructure and
Environmental Private Equity Management III, LLC ("IEPEM"), Argentum Capital
Partners II, L.P. ("Argentum") and NationsCredit Commercial Corporation
("NationsCredit"), which control in the aggregate approximately 96.1% of the
voting power of SPI, will receive a total of $1,250,000 in transaction fees in
connection with the Mergers. At the closing of the Mergers, $750,000 of the
transaction fees will be paid and allocated as follows: KRG - $573,170; IEPEM -
$126,525; Argentum - $25,305; and NationsCredit - $25,000. The remaining
$500,000 balance of the fees will be paid to KRG over two years in equal monthly
installments. Upon the closing of a business acquisition by Holdings, during
each of the first and second years after the closing of the Mergers, all
remaining monthly payments of the transaction fees for that year will become
immediately due and payable. KRG will also be retained by Holdings for a period
of three years to provide transaction advisory services in connection with any
future acquisitions of Holdings following completion of the Mergers. This
agreement may be renewed by the parties on a year-to-year basis for a maximum of
two additional years. Holdings may terminate the transaction advisory services
agreement at any time after its second anniversary upon 90 days' prior written
notice. Under the transaction advisory agreement, KRG will receive a fee of
$75,000 for acquisitions under $5 million, a fee of $100,000 for acquisitions
greater than $5 million but less than $15 million, and a fee of not less than
$100,000 for acquisitions in excess of $15 million. During the third year of the
agreement and any subsequent extension, KRG will receive an annual base advisory
fee of $250,000.

      The principals of KRG, Mark M. King, Bruce L. Rogers, and Charles R.
Gwirtsman, are presently directors of SPI. Mr. Gwirtsman will serve as a
director of Holdings following the Mergers.

      McGettigan, Wick & Co., Inc. will receive a $1,250,000 fee in connection
with the completion of the Mergers. The fee will be payable over not more than
two years, with $750,000 paid at the completion of the Mergers, $250,000 paid
upon the earlier of the closing of the first business acquisition following the
Mergers or the first anniversary of the Mergers, and $250,000 paid upon the
earlier of the closing of the second business acquisition following the Mergers
or the second anniversary of the Mergers.

      The principals of McGettigan, Wick & Co., Inc. are Charles C. McGettigan
and Myron A. Wick III, who are also principals of Proactive Partners, L.P.,
which beneficially controls about 23.6% of the voting power of Modtech. Mr.
McGettigan and Mr. Wick are directors of Modtech and will be directors of
Holdings.

      Indemnification. The Merger Agreement also provides that, from and after
the Effective Time, Holdings and SPI will indemnify, defend, protect and hold
harmless the present and former officers and directors of SPI, subject to
certain limitations, for all claims arising as a result of their service to SPI
or relating to the Merger Agreement and the Mergers. See "Certain Provisions of
The Merger Agreement--Indemnification."

      Registration Rights Agreement. After the completion of the Mergers, the
current executive officers and directors of Modtech and the beneficial owners of
more than 5% of Modtech Common Stock (See "Security Ownership of Certain
Beneficial Owners and Management of Modtech"), the current executive officers
and directors of SPI and the beneficial owners of more than 5% of SPI's Capital
Stock (See, "Security Ownership of Certain Beneficial Owners and Management of
SPI"), and certain individual stockholders of SPI or such



                                       35

   44

beneficial owners, will be entitled to have their shares of Holdings Common
Stock registered for resale to the public under certain conditions. Under a
Registration Rights Agreement between Holdings and these stockholders, in the
event that Holdings determines to register, under the Securities Act of 1933,
any of its equity securities for its own account, these stockholders will be
entitled to notice of Holdings' registration and will be entitled to include in
the registration their shares of Holdings Common Stock specified in a written
request to Holdings.

      These "piggyback" registration rights are subject to certain conditions
and limitations, including the right of Holdings not to include any of these
stockholders' shares among the securities covered by a registration statement if
the aggregate market value of such shares is less than $1 million, or the Board
of Directors of Holdings determines in good faith that including such shares
among the securities covered by the registration statement would have a
materially detrimental effect on the offering and would therefore not be in the
best interest of Holdings. If the offering is underwritten, the underwriter may
also exclude some or all of the shares of these stockholders from the
registration statement, if it determines marketing factors require a limitation
on the number of shares to be underwritten.

ACCOUNTING TREATMENT

      The SPI Merger will be accounted for under the purchase method of
accounting, in accordance with generally accepted accounting principles. Under
the purchase method of accounting, the purchase price of SPI, including direct
costs of the Mergers, will be allocated among the assets acquired and
liabilities assumed based upon their estimated fair values, with the excess
purchase consideration allocated to goodwill. The conversion of Modtech Common
Stock into Holdings Common Stock and Series A Preferred Stock will be treated as
a reorganization, with no change in the recorded amount of Modtech's assets and
liabilities. The financial statements of Modtech will become the financial
statements of Holdings. The results of Holdings' operations will include the
results of operations of SPI commencing at the Closing Date.

      The Unaudited Pro Forma Combined Condensed Financial Statements appearing
elsewhere in this Joint Proxy Statement/Prospectus are based upon certain
assumptions and allocate the purchase price to assets and liabilities based upon
preliminary estimates of their respective fair values. The unaudited pro forma
adjustments and combined amounts are included for informational purposes only.
If the Mergers are consummated, then Holdings's financial statements will
reflect effects of acquisition adjustments only from the Closing Date. THE
ACTUAL ALLOCATION OF THE PURCHASE PRICE MAY DIFFER SIGNIFICANTLY FROM THE
ALLOCATION REFLECTED IN THE UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL
STATEMENTS.

APPROVALS AND CONSENTS

      The Merger Agreement provides that SPI and Modtech will use their best
efforts and cooperate with one another (i) in promptly determining whether any
filings are required to be made or consents, approvals, waivers, permits or
authorizations are required to be obtained under any applicable law or
regulation or from any governmental authorities or third parties in connection
with the Mergers, and (ii) in promptly making any such filings, in furnishing
information required in connection therewith and in timely seeking to obtain any
such consents, approvals, waivers, permits or authorizations.

      Under applicable federal anti-trust law, certain acquisitions may not be
consummated unless notice has been given and certain information furnished to
the Antitrust Division of the United States Department of Justice (the
"Antitrust Division") and the Federal Trade Commission ("FTC") and specified
waiting period requirements have been satisfied, unless earlier termination has
been granted. SPI, Modtech, Proactive Partners, L.P., and Lagunitas Partners
L.P., each filed with the Antitrust Division



                                       36

   45

and the FTC a Notification and Report Form with respect to the Mergers. SPI's 
filing was made October 8, 1998, and the filing of the other three parties were 
made on October 20, 1998. On November 19, 1998, the waiting period will expire.

NASDAQ LISTING

      Holdings will use its best efforts to cause the shares of Holdings Common
Stock issued in the Mergers to be approved for listing on the Nasdaq National
Market, subject to notice of issuance, prior to the Closing Date. This listing
is a condition to closing the Mergers. Holdings does not intend to list the
Holdings Series A Preferred Stock.

      Effective at the Closing Date, Modtech Common Stock will be delisted from
the Nasdaq National Market and deregistered under the Securities Exchange Act of
1934.

RESALES OF STOCK

      Shares of Holdings Common Stock and Holdings Series A Preferred Stock to
be issued in connection with the Mergers will be registered under the Securities
Act of 1933 (the "Securities Act"). Such shares will be freely transferable,
except that shares received by any person who may be deemed to be an affiliate
of SPI or Modtech within the meaning of Rule 145 of the Securities Act may not
be resold except in mergers permitted by such Rule or as otherwise permitted
under the Securities Act. While the shares of Holdings Common Stock will be
listed on the Nasdaq National Market, the shares of Holdings Series A Preferred
Stock will not be listed. There will be no market for Holdings Series A
Preferred Stock and one is not likely to develop.

DISSENTERS' RIGHTS

SPI Stockholders

      You, as a record holder of shares of SPI Capital Stock, will be entitled
to assert dissenters' rights under Article 113 of the Colorado Business
Corporation Act in connection with the Mergers. The following discussion is not
a complete statement of the law pertaining to dissenters' rights under the
Colorado Business Corporation Act and is qualified in its entirety by reference
to the full text of Article 113 reprinted as Annex IV to this Joint Proxy
Statement/Prospectus.

      If you do not wish to accept the SPI Merger Consideration, Article 113
authorizes you to dissent from the Mergers and obtain payment of the "fair
value" for your shares of SPI Capital Stock. To assert dissenters' rights, you
must: (i) provide written notice to SPI, before the vote is taken on the
proposed Mergers, of your intention to demand payment of the fair value for your
shares if the Mergers are completed; and (ii) not vote your shares in favor of
the Mergers. If you do not satisfy these requirements, you will not be entitled
to receive payment for your shares under Article 113.

      "Fair value," with respect to your shares of SPI Capital Stock, means the
value of your shares immediately before the Closing Date of the Mergers,
excluding any appreciation or depreciation in anticipation of the Mergers,
unless such exclusion would be inequitable. Interest will accrue on the fair
value from the Closing Date of the Mergers to the date of payment at the average
rate currently paid by SPI on its principal bank loans.

      You should be aware that the fair value of your shares of SPI Capital
Stock as determined under Colorado law could be greater than, equal to, or less
than the consideration you would receive if you did not elect to assert
dissenters' rights.



                                       37

   46

      If the Mergers are authorized at the SPI Special Meeting, SPI will mail to
you, and all other stockholders who complied with the requirements of Article
113 and are entitled to demand payment of the fair value for their shares of SPI
Capital Stock, a written dissenters' notice. The notice will be given no later
than 10 days after the Closing Date of the Mergers and will be accompanied by a
copy of Article 113. The notice will also (i) state that the Mergers were
authorized and state the Closing Date of the Mergers; (ii) state an address at
which SPI will receive payment demands and the address of a place where
certificates for certificated shares of SPI Capital Stock must be deposited;
(iii) supply a form for demanding payment, which form will request that you
state an address where you would like your payment to be made; (iv) set the date
by which SPI must receive your payment demand and certificates for certificated
shares of SPI Capital Stock, which date will not be less than 30 days after the
date your notice is given; and (v) state all other information that is required
to be given to you under Colorado law.

      In the event that you still wish to assert your dissenters' rights after
receiving your notice from SPI, you must: (i) deliver a completed payment demand
to SPI, which may be on the payment demand form supplied to you by SPI, and (ii)
deposit your certificates for certificated shares of SPI Capital Stock with SPI.
You will still retain all rights of a stockholder, except the right to transfer
your shares of SPI Capital Stock, until the Closing Date of the Mergers. After
the Closing Date of the Mergers, however, you will have only the right to
receive payment of the fair value for your shares of SPI Capital Stock. Except
as described below, both your demand for payment and deposit of certificates are
irrevocable. If you fail to make your payment demand and deposit the share
certificates by the date set in the dissenters' notice delivered by SPI, you
will not be entitled to payment under Article 113.

      Upon the Closing Date of the Mergers or upon SPI's receipt of your payment
demand, whichever is later, SPI will pay to you, and each other dissenter who
complied with the procedures to demand payment under Colorado law, at the
address you provided in your payment demand, the amount SPI estimates to be the
fair value of your shares of SPI Capital Stock, plus accrued interest. Your
payment will be accompanied by SPI's audited balance sheet for the year ended
March 31, 1998, an audited income statement for that year, and an audited
statement of cash flow for that year, as well as the latest available unaudited
financial statements, if any, for the interim period. Also included with your
payment will be a statement of SPI's estimate of the fair value of your shares,
an explanation of how the interest on your payment was calculated, and a
statement of your right to demand additional payment under Article 113. In
addition, SPI will again provide you with a copy of the full text of Article 113
of the Colorado Business Corporation Act.

      If the Closing Date of the Mergers has not occurred within 60 days after
the date set by which SPI must receive your payment demand, SPI will return your
deposited certificates. If, however, the Closing Date of the Mergers
subsequently occurs, then SPI will send to you a new dissenters' notice, and all
of the provisions of Article 113 summarized above will again be applicable.

      As mentioned above, you may have the right under Colorado law to demand
additional payment for your shares of SPI Capital Stock. If you believe that the
amount paid or offered by SPI for your shares is less than the fair value or
that the interest due was incorrectly calculated, or if SPI fails to make
payment within 60 days after the date set by which SPI must receive your payment
demand, or if SPI fails to return the deposited certificates as required under
Article 113, you may give written notice to SPI of your estimate of the fair
value of your shares, and of the amount of interest due, and you may demand
payment of such estimate, less any payment already made by SPI. You will waive
your right to demand payment of your estimate unless you deliver your demand to
SPI within 30 days after SPI made or



                                       38

   47

offered payment of the fair value of your shares of SPI Capital Stock.

      If your demand for additional payment remains unresolved, SPI may, within
60 days after receiving your demand, commence a court proceeding and petition
the District Court for Denver County, Colorado, to determine the fair value of
your shares, plus accrued interest. If SPI does not commence the proceeding
within the 60-day period, it shall pay to you, and each other dissenter whose
demand for additional payment remains unresolved, the amount demanded. The court
may assess the costs of the court proceedings between the parties as it deems
equitable.

      Under Colorado law, if you decide to dissent and obtain payment of the
fair value for your shares of SPI Capital Stock, you may not challenge the
Mergers, unless the Mergers are unlawful or fraudulent with respect to the
stockholders of SPI.

Modtech Stockholders

      Since Modtech's Common Stock is traded on the Nasdaq National Market, you
will not be entitled to dissenters' rights if you object to the Mergers, unless
your shares are subject to restrictions on transfer imposed by Modtech or by law
or regulation, or unless the holders of at least 5% of Modtech's outstanding
Common Stock make appropriate demands under Chapter 13 of the California General
Corporation Law (the "California Corporations Code"). The following discussion
is not a complete statement of the law pertaining to the rights of such
"dissenting stockholders" under the California Corporations Code and is
qualified in its entirety by reference to the full text of Chapter 13, which is
reprinted as Annex III to this Joint Proxy Statement/Prospectus.

      Under the California Corporations Code, if you do not wish to accept the
Modtech Merger Consideration upon completion of the Merger, you may elect to
receive payment for the fair market value of your shares if: (1) you meet the
requirements of the preceding paragraph; (2) your shares were outstanding on the
Record Date; (3) your shares were not voted in favor of the Mergers; (4) you
make a written demand that Modtech purchase your shares of Modtech Common Stock
at fair market value; and (5) you submit your stock certificates for
endorsement. Your shares will then be considered "Dissenting Shares."

      The fair market value of your Dissenting Shares is determined as of the
day before the first announcement of the terms of the Mergers, excluding any
appreciation or depreciation as a consequence of the proposed Mergers, but
adjusted for any stock split, reverse stock split or stock dividend that becomes
effective thereafter.

     Within 10 days following approval of the Mergers by Modtech stockholders,
Modtech must mail to you and each other holder of shares of Modtech Common Stock
on the Record Date not voted in favor of the Mergers, a notice of the approval
of the Mergers, a statement of the price determined by Modtech to represent the
fair market value of the Dissenting Shares (which shall constitute an offer by
Modtech to purchase such Dissenting Shares at such stated price), and a
description of the procedures for you and such holders to exercise your rights
under Chapter 13 of the California Corporations Code as dissenting stockholders.

     Within 30 days after the date on which the notice of the approval of the
Mergers by the outstanding shares of Modtech Common Stock is mailed to you, you
must demand that Modtech repurchase your Dissenting Shares in a statement
setting forth the number and class of Dissenting Shares held of record by you
that you are demanding that Modtech purchase, and a statement of what you claim
to be the fair market value of the Dissenting Shares as of the day before the
announcement of the proposed Mergers. The statement of fair market value in your
demand will be treated as an offer by you to sell the Dissenting Shares at such
price to Modtech. You



                                       39

   48

must also submit to Modtech certificates representing any Dissenting Shares that
you demand Modtech purchase, so that such Dissenting Shares may either be
stamped or endorsed with the statement that the shares are Dissenting Shares or
exchanged for certificates of appropriate denomination so stamped or endorsed.

     If, upon your surrender of the certificates representing the Dissenting
Shares, Modtech and you agree upon the price to be paid for the Dissenting
Shares and agree that such shares are Dissenting Shares, then the agreed price
is required by law to be paid to you within the later of 30 days after the date
of such agreement or 30 days after any statutory or contractual conditions to
the consummation of the Mergers are satisfied or waived.

      If Modtech and you disagree on the price for such Dissenting Shares or
disagree as to whether such shares are entitled to be classified as Dissenting
Shares, you have the right to bring an action in California Superior Court to
resolve the dispute. The action must be brought within six months after the date
on which the notice of the approval of the Mergers by Modtech stockholders is
first mailed. In such action, the California Superior Court may determine
whether the shares of Modtech Common Stock held by you are Dissenting Shares,
the fair market value of such shares, or both.

      You should assume that Modtech will not take any action to perfect your
dissenters' rights. To exercise your dissenters' rights, you should strictly
comply with the procedures set forth in Chapter 13 of the California
Corporations Code. You should consult with your legal advisor before electing or
attempting to exercise your dissenters' rights. Failure to follow any Chapter 13
procedures may result in termination or waiver of dissenters' rights under
Chapter 13.

      The California Corporations Code provides, among other things, that you
may not withdraw the demand for payment of the fair market value of your
Dissenting Shares unless Modtech consents to such request for withdrawal. If you
perfect your dissenters' rights you will not be entitled to surrender your
Modtech Common Stock for payment of the Modtech Merger Consideration.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

      Modtech and SPI have each made forward-looking statements in this document
(and in certain documents that are incorporated by reference in this Joint Proxy
Statement/Prospectus) that are subject to risks and uncertainties. These
statements are based on the beliefs and assumptions of the respective company's
management, and on information currently available to such management.
Forward-looking statements include the information concerning possible or
assumed future results of operations of Modtech, SPI and Holdings set forth
under "Summary," "The Mergers--Background of the Mergers," "The Mergers--Reasons
for the Mergers; Recommendations of the Boards of Directors" and "Unaudited Pro
Forma Condensed Combined Financial Statements," and statements preceded by,
followed by, or that include the words "believes," "expects," "anticipates,"
"intends," "plans," "estimates" or similar expressions.



                                       40

   49

      Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. The future results and stockholder values
of the combined companies following the Mergers may differ materially from those
expressed in these forward-looking statements. Many of the factors that will
determine these results and values are beyond Modtech's, SPI's, and Holdings'
ability to control or predict. Stockholders are cautioned not to place undue
reliance on any forward-looking statements. In addition, Modtech, SPI and
Holdings do not have any intention or obligation to update forward-looking
statements after they distribute this Joint Proxy Statement/Prospectus, even if
new information, future events or other circumstances have made them incorrect
or misleading.

      Actual events and results may differ materially from those expressed or
forecasted in forward-looking statements due to a number of factors. The
principal important risk factors that could cause the combined companies' actual
performance and future events and actions to differ materially from such
forward-looking statements, include, but are not limited to, changes in
legislation relating to funding for modular classrooms, changes in building code
laws or regulations, and changes in general economic and market factors that
affect the prices of securities or the industries in which Modtech and SPI do
business.

      SPI. The SPI Board has fixed the close of business on _________, 1998 (the
"Record Date") as the record date for determining the holders of SPI Capital
Stock entitled to notice of, and to vote at, the SPI Special Meeting. Only
holders of record of SPI Capital Stock at the close of business on the Record
Date will be entitled to notice of, and to vote at, the SPI Special Meeting.

      The presence at the SPI Special Meeting, either in person or by proxy, of
the holders of a majority of the voting power represented by the SPI Common
Stock and SPI Preferred Stock (voting together and not as separate classes of
stock) is necessary to constitute a quorum in order to transact business at the

Special Meeting, such meeting will be adjourned or postponed in order to solicit
additional proxies.

      MODTECH. The Modtech Board has fixed the close of business on _________,
1998 as the record date for determining the holders of Modtech Common Stock
entitled to notice of, and to vote at, the Modtech Special Meeting. Only holders

Meetings--Voting of Proxies."

      The presence at the Modtech Special Meeting, either in person or by proxy,
of the holders of a majority of the outstanding Modtech Common Stock entitled to
vote, is necessary to constitute a quorum of the Modtech Common Stock, in order

will be adjourned or postponed in order to solicit additional proxies.

VOTES REQUIRED

      SPI. Approval of the proposal to adopt the Merger Agreement and the
Mergers, including the SPI Merger, will require the affirmative vote of 70% of
the combined voting power of the outstanding shares of SPI Common Stock and SPI
Preferred Stock entitled to vote thereon. Under applicable Colorado law, in
determining whether the proposal to approve and adopt the Merger Agreement and
the Mergers has received the requisite number of affirmative votes, abstentions
will be counted and have the same effect as a vote against the proposals.

      MODTECH. Approval of each of the proposals to adopt the Merger Agreement
and the Mergers, including the Modtech Merger, will require the affirmative vote
of the majority of the voting power of the outstanding shares of Modtech Common
Stock entitled to vote thereon. Under applicable California law, in determining
whether either proposal has received the requisite number of affirmative votes,
abstentions will be counted and have the same effect as a vote against the
proposals. Brokers who hold shares of Modtech Common Stock as nominees, in the
absence of instructions from the beneficial owners thereof, will not have
discretionary authority to vote such shares for the approval and adoption of the
Merger Agreement and the Mergers. Any shares which are not voted because the
nominee-broker lacks such discretionary authority will be counted and have the
same effect as a vote against the proposals.

SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN STOCKHOLDERS

      SPI. As of the close of business on the Record Date, SPI's directors and
executive officers and their affiliates had the right to vote _______
outstanding shares of SPI Common Stock and _________ outstanding shares of SPI
Preferred Stock (collectively representing approximately ______% of the voting
power of all classes of SPI Capital stock).

directors and executive officers and their affiliates had the right to vote
________________ outstanding shares of Modtech Common Stock (collectively
representing approximately % of the voting power of the Modtech Common Stock).

VOTING OF PROXIES

      Shares represented by properly executed proxies received in time for the
Modtech or SPI Special Meeting will be voted at the meeting in the manner
specified by such proxies. You should be aware that, if your proxy is properly
executed but does not contain voting instructions, your proxy will be voted FOR
approval of the Merger Agreement, including the Mergers. It is not expected that
any matter other than as described herein will be brought before the Modtech
Special Meeting or the SPI Special Meeting. If other matters are properly
presented before either of these meetings, the persons named in your proxy will
have authority to vote on such matters without consulting you. These matters may
include a proposal to adjourn or postpone the meeting in order to solicit
additional votes in favor of the Merger Agreement and the Mergers.



                                       43

   52

REVOCABILITY OF PROXIES

      The grant of a proxy on the enclosed Modtech or SPI proxy card does not
preclude a stockholder from voting in person. A stockholder of SPI may revoke a
proxy at any time prior to its exercise by:

- -     delivering, prior to the SPI Special Meeting, to SPI, 9550 Hermosa Avenue,
      Rancho Cucamonga, California 91730, Attention: Secretary, a written notice
      of revocation bearing a later date or time than the proxy;

- -     delivering to the Secretary of SPI a duly executed proxy bearing a later
      date or time than the revoked proxy; or

- -     attending the SPI Special Meeting and voting in person.

       A stockholder of Modtech may revoke a proxy at any time prior to its
exercise by:

- -     delivering, prior to the Modtech Special Meeting, to the Secretary of
      Modtech, James D. Goldenetz, Modtech, Inc., 2830 Barrett Avenue, Perris,
      California 92571, a written notice of revocation bearing a later date or
      time than the proxy;

- -     delivering to the Secretary of Modtech a duly executed proxy bearing a
      later date or time than the revoked proxy; or

- -     attending the Modtech Special Meeting and voting in person.

      Attendance at the Modtech Special Meeting or the SPI Special Meeting will
not by itself constitute revocation of a proxy. Neither Modtech nor SPI expects
to adjourn their Special Meeting for a period of time long enough to require the
setting of a new Record Date for the meeting. If an adjournment occurs, it will
have no effect on the ability of either Modtech's or SPI's stockholders of
record as of the Record Date to exercise their voting rights or to revoke any
previously delivered proxies.

SOLICITATION OF PROXIES

      Modtech will pay 68% of the costs of preparing, filing, printing and
mailing this Joint Proxy Statement/Prospectus, including filing fees, and SPI
will pay 32% of such costs. Each company shall bear 100% of any additional costs
incurred by it in soliciting proxies from its stockholders. Arrangements will be
made with brokerage houses and other custodians, nominees and fiduciaries for
the forwarding of solicitation material to the beneficial owners of Modtech
Common Stock held of record by such persons, and Modtech will reimburse such
company's custodians, nominees and fiduciaries for their reasonable
out-of-pocket expenses in connection therewith. In addition to solicitation by
mail, the directors, officers and employees of each company and their
subsidiaries may solicit proxies from their stockholders by telephone, telegram
or in person.

      Neither Modtech nor SPI have retained any third party to assist them in
soliciting proxies in connection with the Modtech Special Meeting or the SPI
Special Meeting.


DO NOT SEND STOCK CERTIFICATES IN WITH YOUR PROXY CARD.

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT

      The following is a brief summary of certain provisions of the Merger
Agreement, which is attached as Annex I to this Joint Proxy Statement/Prospectus

CONDUCT OF BUSINESS PENDING THE MERGERS

      Modtech and SPI have each agreed in the Merger Agreement to take or
refrain from taking certain actions from the date of the Merger Agreement until
the completion of the Mergers. Subject to certain exceptions set forth in the
Merger Agreement, they have agreed as follows:

      Interim Operations. They will (1) conduct and cause each of their
subsidiaries to conduct their businesses according to their ordinary and usual
course; and (2) use and cause their subsidiaries to use their best efforts to
preserve intact their business organizations and good will in all material
respects, keep available the services of their officers and employees as a

material contract rights not in the ordinary course of business.

      Further Assurances. They will use all reasonable efforts to take all other
actions necessary to complete the Mergers.

TERMINATION

      The Merger Agreement may be terminated and abandoned at any time prior to
the Effective Time, whether before or after approval of the Mergers by the
stockholders of SPI and Modtech:



                                       46

   55

- -     by mutual written consent of Modtech and SPI;

- -     by either party if (a) any court or other United States governmental body
      has taken any action enjoining, restraining or otherwise prohibiting one
      or both of the Mergers; (b) the Mergers have not been completed by March
      28, 1999 (other than due to the breach of the Merger Agreement by the
      party seeking to terminate the Merger Agreement); (c) any required
      approval of the stockholders of either party has not been obtained; or (d)
      if the other party materially breaches its representations, warranties or
      agreements under the Merger Agreement and fails to perform any of its
      material obligations under this Agreement and such breach has not been
      cured within 10 days after receipt of written notice of such failure;

- -     by either party if the other party's Board withdraws or adversely modifies
      its recommendation to approve the Merger Agreement or the Mergers, or
      resolves to do any of the foregoing;

- -     by Modtech or SPI if they receive a proposal from a third party to merge,
      consolidate, or enter into a similar transaction , or to sell all or any
      significant portion of its assets or equity securities ("Third Party
      Acquisition Proposal") and their Board decides that the Third Party
      Acquisition Proposal is a "Superior Proposal" by determining: (1) in good
      faith that the Third Party Acquisition Proposal is more favorable to their
      stockholders than the Mergers; and (2) upon the advice of their legal
      counsel that to continue to recommend that their stockholders vote in
      favor of the Mergers after receipt of the Third Party Acquisition Proposal
      would not be consistent with their fiduciary duties. After making the
      foregoing determinations, the terminating party's Board must give the
      other party three days prior written notice of its intent to terminate the
      Merger Agreement. The notice must include a detailed summary of the terms
      and conditions of the Superior Proposal.

      Upon termination, the Merger Agreement will become void and have no
effect, without any liability or obligation on the part of Modtech or SPI, other
than the payment of expenses as described in "Certain Provisions of the Merger
Agreement -- Fees and Expenses" below, and the payment of the termination fee
described below. Termination will not relieve any party from any breach of the
representations, warranties, covenants or agreements set forth in the Merger
Agreement prior to termination.

TERMINATION FEE

      If Modtech satisfies all conditions to completion of the Mergers within
its control and does not take any action to prevent or unreasonably delay
completion of the Mergers, it will be entitled to a termination fee from SPI if
SPI terminates the Merger Agreement because of its receipt of a Superior
Proposal, or if Modtech terminates the Merger Agreement because:

- -     SPI materially breaches any of its representations, warranties or
      agreements under the Merger Agreement and fails to cure the breach within
      ten days after receipt of notice of the breach;

- -     the required approval of the SPI stockholders has not been obtained; or

- -     the SPI Board has withdrawn or adversely modified its recommendation of
      approval of the Merger Agreement or the Mergers.

      The termination fee to be paid by SPI will be equal to Modtech's fees and
expenses related to the Mergers, plus $2 million.

      If SPI satisfies all conditions to completion of the Mergers within its
control and does not take any action to prevent or unreasonably delay completion
of the Mergers, it shall be entitled to a termination



                                       47

   56

fee from Modtech if Modtech terminates the Merger Agreement because of its
receipt of a Superior Proposal, or if SPI terminates the Merger Agreement
because:

- -     Modtech materially breaches any of its representations, warranties or
      agreements under the Merger Agreement and fails to cure the breach within
      ten days after receipt of notice of the breach;

- -     the required approval of the Modtech stockholders has not been obtained;
      or

- -     the Modtech Board has withdrawn or adversely modified its recommendation
      of approval of the Merger Agreement or the Mergers.

      The termination fee to be paid by Modtech will be equal to SPI's fees and
expenses related to the Mergers plus $2 million.

      The termination fees are the sole remedy of Modtech and SPI if the Merger
Agreement is terminated for any of the reasons described above.

INDEMNIFICATION

      The Merger Agreement provides that, after the Effective Time, Holdings
will indemnify, defend and hold harmless the current and former directors,
officers and employees of Modtech, SPI and their respective subsidiaries (each,
an "Indemnified Party")



                                       48

   57


against all costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of actions or omissions occurring
at or prior to the Closing Date (including, without limitation, the Mergers) to
the fullest extent that such persons are indemnified under the laws of the
States of California or Colorado and the certificates of incorporation and
bylaws, as in effect on the date thereof, of Modtech, SPI and their respective
subsidiaries or any existing indemnification agreement with either Modtech or
SPI. In the event of any such loss, expense, claim, damage or liability,
Holdings will cooperate in the defense of any such matter and any determination
required to be made with respect to whether an officer's or director's conduct
complies with the standards set forth under applicable law and any such
certificate of incorporation or bylaws will be made by independent counsel
(which will not be counsel that provides material services to Holdings or its
subsidiaries) selected by Holdings and reasonably acceptable to such officer or
director; provided, that in the absence of applicable judicial precedent to the
contrary, such counsel, in making such determination, will presume such
officer's or director's conduct complied with such standard and Holdings will
have the burden to demonstrate that such officer's or director's conduct failed
to comply with such standard.

      In addition, the Merger Agreement provides that, for a period of six years
after the Effective Time, Holdings will maintain officers' and directors'
liability insurance covering those of the Indemnified Parties who are covered,
in their capacities as current or former officers and directors of Modtech, by
Modtech's existing officers' and directors' liability insurance policies, and
those of the Indemnified Parties who are covered in their capacities as current
or former officers and directors of SPI, by SPI's existing officers' and
directors' liability insurance policies, on terms substantially no less
advantageous to such Indemnified Parties than such existing insurance.
Additionally, Holdings is required to keep in effect provisions in its and
Modtech's and SPI's organizational documents providing for exculpation of
director and officer liability and its indemnification of the indemnified
parties to the fullest extent permitted under the Delaware, California or
Colorado corporate statutes, as applicable, which provisions will not be amended
except as required by applicable law or except to make changes permitted by law
that would enlarge the indemnified parties' right of indemnification.

FEES AND EXPENSES

      Whether or not the Mergers are consummated, all costs and expenses
incurred in connection with the Merger Agreement and the Mergers contemplated
thereby will be paid by the party incurring the expenses, except that the
following expenses will be paid 68% by Modtech and 32% by SPI for:

- -     the filings made under applicable anti-trust laws for Modtech, SPI and
      their affiliates;

- -     the Securities and Exchange Commission's filing fee for the registration
      statement for Holdings Common Stock on Form S-4 of which this Joint Proxy
      Statement/Prospectus is a part; and

- -     the expenses incurred in preparing, printing and mailing the registration
      statement and the Joint Proxy Statement/Prospectus.

      In addition, SPI will reimburse Modtech for 32% of the fee paid by Modtech
to DLJ for the Fairness Opinion.

      The Merger Agreement may be amended by the parties at any time before or
after required approval of the Mergers by the stockholders of SPI and of
Modtech; except that after such approvals,



                                       49

   58

changes to the amount of cash and Holdings Common Stock to be received by the
Modtech stockholders or the SPI stockholders may not be made without further
approval by such stockholders. Prior to the Effective Time, the parties may (i)
extend the time for the performance of any obligation or other act of any other
party to the Merger Agreement, (ii) waive any inaccuracies in the
representations and warranties contained in the Merger Agreement or in any
document delivered pursuant thereto and (iii) waive compliance with any of the
agreements or conditions contained in the Merger Agreement. All waivers must be

                            THE BUSINESS OF HOLDINGS

      Following the Mergers, Holdings will be one of the leading modular
building manufacturers in the country with substantial product and geographic
diversification. It will be the leading provider of modular classrooms in the
State of California and a leading provider of modular buildings to customers in
California, Nevada, Arizona, New Mexico, Utah, Colorado and Texas and other
neighboring states.

      The Mergers will create a company with pro forma revenues of approximately
$215 million for the 12 months ended December 31, 1997 and with the size and
scope to allow for purchasing efficiencies and other manufacturing and marketing
synergies. The Mergers will also strengthen and deepen the management team of
the combined enterprise.

                             THE BUSINESS OF MODTECH

GENERAL

      Modtech's modular relocatable classrooms are designed, engineered and
manufactured in accordance with structural and seismic safety specifications
adopted by the California Department of State Architects. These standards are
more rigorous than the requirements for other portable units, and supersede all
local building codes. Modtech subcontracts with structural engineering firms to
interface with each school district's architect or engineer to process project
specifications through the Department of State Architects.

      Conventional school facilities constructed by school districts using funds
from the State Office of Public School Construction typically require two to
three years for approval and funding. Standardized factory-built school
classrooms like Modtech's, based on pre-approved plans and specifications, can
be approved by the State for construction in as little as 90 days. In all cases,
continuous on-site inspection by a licensed architect or structural engineer is
required during actual manufacturing of the classrooms, with the school district
obligated to reimburse the Department for the costs of such inspection.

      In addition to its standard largely pre-fabricated classrooms, Modtech
also manufactures and installs relocatable customized classrooms which are
modular in design but assembled on-site using components manufactured by
Modtech, together with components purchased from third-party suppliers.
Modtech's classrooms vary in size from two modular units containing a total of
960 square feet to 20 units that can be joined together to produce a facility
comprising 9,600 square feet. Larger configurations are also possible. Typical
prices for Modtech's standard classrooms range from $29,000 to $34,000, while
prices for a custom classroom generally exceed $50,000, depending upon the
extent of customization required.

CLASSROOM CUSTOMERS

      Modtech markets and sells its modular classrooms primarily to California
school districts. Modtech also sells its classrooms to the State of California
and leasing companies, both of which lease the classrooms principally to
California school districts. Sales of classrooms accounted for 94.2%, 98.1% and
98.9% of Modtech's total net sales for the years ended December 31, 1996 and
1997 and the six months ended June 30, 1998, respectively. Modtech's customers
typically pay cash from general operating funds or the proceeds of local bond
issues, or lease classrooms through banks, leasing companies and other private
funding sources.

      Sales of classrooms to individual California school districts accounted
for approximately 74.5%, 71.1% and 73.2%, respectively, of Modtech's net sales
during the years ended December 31, 1996 and 1997 and the six months ended June
30, 1998, with sales of classrooms to third-party lessors to California school
districts during these periods accounting for approximately 7.2%, 19.1% and
14.2%, respectively, of Modtech's net sales. The mix of school districts to
which Modtech sells its products varies somewhat from year to year. Sales of
classrooms directly to the State of California during the six months ended June
30, 1998 represented approximately 11.5% of Modtech's net sales for the period,
compared to approximately 7.9% of Modtech's 1997 net sales and approximately
12.5% of Modtech's 1996 net sales. Sales of classrooms to private schools, day
care providers and out-of-state customers accounted for less than 1%of Modtech's
net sales during the years ended December 31, 1996 and 1997 and the six months
ended June 30, 1998. One of the lessors to which Modtech sells classrooms for
lease to California school districts is affiliated with Modtech through common
ownership by two of Modtech's directors. During the years ended December 31,
1996 and 1997 and the six months ended June 30, 1998, sales of classrooms to
this affiliated leasing



                                       52

   61

company comprised approximately 2.9%, 2.2% and 2.7, respectively, of Modtech's
net sales. See "Where You Can Find More Information."

OTHER PRODUCTS

      In addition to modular relocatable classrooms, Modtech also manufactures
modular, portable buildings which can be used as office facilities and
construction trailers and for other commercial purposes. During the years ended
December 31, 1996 and 1997 and the six months ended June 30, 1998, sales of such
modular, portable buildings to commercial customers accounted, in the aggregate,
for approximately 5.8%, 1.9% and 1.1%, respectively, of Modtech's net sales.
Modtech also manufactures a small number of modular structures that house and
shelter electronic equipment used in the wireless telecommunications industry.
During the years ended December 31, 1996 and 1997 and the six months ended June
30, 1998, sales of modular telecommunications equipment shelters accounted for
less than 1.0% of Modtech's net sales for each period.

SALES AND MARKETING

      Modtech's classroom sales force is currently divided into three marketing
regions: Northern, Central and Southern California. Modtech currently employs
three classroom salespersons, each of whom is compensated on a commission basis.
These salespersons maintain contact with the individual school districts in
their respective marketing regions on a quarterly basis. They are also in
contact with architects and building inspectors employed by the school
districts, as well as school officials who may be in a position to influence
purchasing decisions.

      Most of Modtech's contracts are awarded on an open bid basis. The
marketing process for many of Modtech's contracts begins prior to the time the
bid process begins. After Modtech selects bids or contracts that it desires to
pursue, Modtech's marketing and engineering personnel interface directly with
various school boards, superintendents or architects during the process of
formulating bid or contract specifications. Modtech prepares its bids or
proposals using various criteria, including current material prices, historical
overhead costs and a targeted profit margin. Substantially all of Modtech's
contracts are turnkey, including engineering and design, manufacturing,
transportation, installation and necessary site work. Open bid contracts are
normally awarded to the lowest responsible bidder.

      A fourth salesperson is charged with increasing Modtech's sales of
buildings to the commercial and telecommunications markets. In addition, Modtech
has two salespeople who focus on the sale of classrooms in Nevada and Arizona,
and to private schools and day care operators in California.

MANUFACTURING AND ON-SITE INSTALLATION

      Modtech uses an assembly line approach in the manufacture of its
standardized classrooms.

      Modtech is vertically integrated in the manufacture of its standardized
modular classrooms, in that Modtech fabricates substantially all of its own
metal components at its facility in Perris, California. Modtech believes that
the ability to fabricate its own metal components helps it reduce the costs of
its products and to control their quality and delivery schedules. Modtech
maintains a quality control system throughout the manufacturing process, under
the supervision of its own quality control personnel and inspectors engaged by
its customers.

      Modtech oversees installation of its modular classrooms on-site, using its
own employees for job supervision as a general contractor and, whenever
possible, for utility hook-ups and other tasks. In many custom projects, Modtech
performs or supervises subcontracted electrical, plumbing, grading, paving and
foundation work, landscaping and other site preparation work and services.
Subcontractors are typically used for larger utility, grading, concrete and
landscaping jobs. Modtech has a general contractor's license in the State of
California.


                                       53

   62


      In addition to approvals by the Department of State Architects, licensed
inspectors representing various school districts are on-site at each
manufacturing facility of Modtech to continuously inspect the construction of
classrooms for structural integrity. On-site inspections after installation are
also made by local fire departments for purposes of determining adequate
accessibility.

      Modtech currently has five manufacturing facilities. Two are located in
Perris, California, which is approximately 60 miles east of Los Angeles. Modtech
has two additional facilities near Lathrop, California. Lathrop is located
approximately 75 miles east of San Francisco. Modtech's fifth facility is
located in Glendale, Arizona, approximately ten miles from Phoenix. Modtech
currently has a total of eight production lines in operation. A ninth production
line is scheduled to be added at the Lathrop plant in late 1998.

WARRANTIES

      The standard contractual warranty for Modtech's modular relocatable
classrooms is one year, although it may be varied by contract specifications.
Purchased equipment installed by Modtech, such as air conditioning units, carry
the manufacturers' standard warranty. Warranty costs have not been material in
the past.

SUPPLIES

      Modtech believes that there are multiple sources of supplies available for
all raw materials and equipment used in manufacturing its classrooms, most of
which are standard construction items such as steel, plywood and wallboard.

BACKLOG

      Modtech manufactures classrooms to fill existing orders only, and not for
inventory. As of December 31, 1997, the backlog of sales orders was
approximately $71.0 million, up from approximately $4.1 million at December 31,
1995 and $58.0 million at December 31, 1996. Backlog at June 30, 1998 was $60.1
million, compared to backlog of $80.4 million at June 30, 1997. Only orders
which are scheduled for completion during the following 12-month period are
included in Modtech's backlog. The rate of booking new contracts can vary from
month to month, and customer changes in delivery schedules can occur. For these
reasons, among others, Modtech's backlog as of any particular date may not be
representative of actual sales for any succeeding period.

COMPETITION

      The modular relocatable classroom business is highly competitive. Based on
1997 net sales, Modtech believes that it is the largest modular relocatable
classroom manufacturer in California. The primary competitors of Modtech for
standardized classrooms are believed to be Aurora Modular Industries in Southern
California and American Modular Systems in Northern California. Profiles
Structures in Southern California and Design Mobile Systems in Northern
California are Modtech's primary competitors in the market for higher-priced,
customized classrooms. Each of these four competitors is a privately-owned
company. Modtech believes that additional competitors may enter the market in
the future, some of whom may have significantly greater capital and other
resources than are available to Modtech, and that competition may therefore
increase.

      Modtech believes its vertically integrated, assembly line approach to
manufacturing enables it to be one of the low-cost producers of standardized,
modular relocatable classrooms in California. Unlike many of its competitors,
Modtech manufactures most of its own metal components, which allows Modtech to
maintain quality control over these components and to produce them at a lower
average cost than that at which they could be obtained from outside sources.
Modtech also believes that the quality and appearance of its buildings, and its
reputation for reliability in completion of its contracts, enable it to maintain
a favorable position among its competition.



                                       54

   63

      Beyond a radius of approximately 300 miles, Modtech believes that
transportation costs typically will either significantly increase the prices at
which it bids for given projects, or will substantially erode Modtech's gross
profit margins.

PERFORMANCE BONDS

      A substantial portion of Modtech's sales require that Modtech provide
bonds to ensure that the contracts will be performed and completed in accordance
with contract terms and conditions, and to assure that subcontractors and
materialmen will be paid. In determining whether to issue a performance bond on
behalf of Modtech, bonding companies consider a variety of factors concerning
the specific project to be bonded, as well as Modtech's levels of working
capital, stockholders' equity and outstanding indebtedness. From time to time,
Modtech has had difficulty in obtaining bonding for a given project. It may
encounter such difficulty again in the future.

REGULATION OF CLASSROOM CONSTRUCTION

      In 1933, the California Legislature adopted the Field Act, which generally
provides that school facilities must be constructed in accordance with more
rigorous structural and seismic safety specifications than are applicable to
general commercial buildings. Under the Field Act, the Department of General
Services, through the Department of State Architects, has prescribed extensive
regulations regarding the design and construction of school facilities, and
reviews all plans for the construction of material modifications to any school
building. Construction authorization is not given unless the school district's
architect certifies that a proposed project satisfies construction cost and
allowable area standards. In addition, the Field Act provides for the submittal
of complete plans, cost estimates, and filing fees by the school district to the
Department of General Services, for the adoption of regulations setting minimum
qualifications for the preparation of plans and specifications, and the
supervision of school construction by a licensed architect or structural
engineer.

FUNDING

      The demand for modular relocatable classrooms in California is affected by
various statutes. These statutes prescribe the methods by which Modtech's
customers, primarily individual school districts, obtain funding for the
construction of new school facilities, and the manner in which available funding
is to be spent by the school districts.

      Financing for new school construction and rehabilitation of existing
schools by California school districts is currently provided, at the state
level, by funds derived from general revenue sources or statewide bond issues.
At the local level, financing is provided by local bond issues and fees imposed
on the developers of residential, commercial and industrial real property.
Historically, the primary source of financing for the purchase or lease of
relocatable classrooms has been state funding.

      Class Size Reduction Program. In November 1996, California implemented the
Class Size Reduction Program in response to overcrowding in classrooms in the
state. Under this program, public schools that reduce class size to 20 students
in kindergarten through third grade receive additional funds. New classrooms may
be added by reconfiguring existing space, building new conventional classrooms,
or purchasing or leasing modular relocatable classrooms.

      General Obligation Bonds. Until the adoption of the Class Size Reduction
Program in 1996, the most important source of funding at the State level for new
school facilities was through the issuance and sale of statewide general
obligation bonds which must be placed on statewide ballots and approved by the
voters.

       Bond Financing. Under the School Building Lease - Purchase Law of 1976,
the State Allocation Board is empowered to purchase or lease school facilities
using funds from the periodic issuance of general obligation bonds of the State
of California. These purchased or leased school facilities may be made available
by the State Allocation Board to school districts. Certain matching funds,
usually



                                       55

   64

derived from fees imposed on real estate developers, are required to be supplied
by the school districts seeking state funded facilities. If the school districts
acquire relocatable structures using these developer fees, the amount of the
required matching funds is reduced by the cost of such facilities. This
reduction in matching funds is intended to provide an incentive for school
districts to lease relocatable classrooms. As a condition of funding any project
under this program, at least 30% of new classroom space to be added must be
comprised of relocatable structures, unless relocatable structures are not
available or special conditions of terrain, climate or unavailability of space
make the use of relocatable structures impractical. In addition, State funds
under this program are not available to school districts which are determined to
have an adequate amount of square footage available for their student
population.

      Senate Bill 50, which was recently passed by the California Legislature,
revised the School Building Lease -- Purchase Law of 1976 by eliminating the
requirement that at least 30% of all new classroom space being added using
California state funds must be relocatable classrooms. In general, it replaced
this provision with a requirement that, in order for school districts to
increase the amount of funds to be received from developers in excess of the
current statutory level, the school districts must show that 20% of all
classroom space in the district, not just new space to be added, consists of
relocatable classrooms. The bill also placed a $9.2 billion bond issue on the
November 1998 ballot. The bill will not become operative unless the $9.2 billion
bond issue is approved by a majority of the California voters. The bill
allocates from the bond issue $2.9 billion for growth and new construction, and
$2.2 billion for modernization and reconstruction through the year 2001. In
addition, it allocates $700 million for class-size reductions to fully implement
the program from kindergarten through third grade. The costs to implement the
foregoing will include land acquisition costs, hiring of new teachers,
remodeling of existing structures and construction of new permanent and
relocatable structures. The bill does not designate the specific usage of funds,
and the actual amount spent on relocatable classrooms will vary among school
districts.

      California Emergency Classroom Law of 1979. Under the California Emergency
Classroom Law of 1979, the State Allocation Board may spend up to $35 million
per year from available funds to purchase relocatable classrooms to be leased to
school districts. Relocatable classrooms are not available to school districts
under this program if the school district has available local bond proceeds that
could be used to purchase classroom facilities, unless the district has approved
projects pending under the School Building Lease-Purchase Law of 1976. The State
has, in the past, funded this program primarily from the proceeds of statewide
bond issues approved by voters.

      Budget Allocations. Proposition 98, which was approved in 1988, requires
the State to allocate annually from the State's budget, for the support of
school districts and community college districts, a minimum amount equal to the
same percentage of funds as was appropriated for the support of those
institutions in fiscal year 1986-87. While this requirement may be suspended for
a given year by emergency legislation, it has the effect of limiting the ability
of the California legislature to reduce the level of school funding from that in
existence in 1986-87. The State raises the necessary funds through proceeds from
the sale of statewide bond issues, income tax revenues and other revenues. A
recent reduction in California's corporate tax rates, and a proposed reduction
of personal income tax rates might affect future levels of the State's income
tax revenues.

      Local Funding. Local school districts in California have the ability to
issue local general obligation bonds for the acquisition and improvement of real
property for school construction. These bond issues require the approval of
two-thirds of the voters in the district and are repaid using the proceeds of
increases in local property taxes. A local school district may also levy
developer fees on new development projects in the district, subject to a maximum
rate set by state law. The developer fees can only be levied if the project can
be shown to contribute to the need for additional school facilities and the fee
levied is reasonably related to such need. In addition, California law provides
for the issuance



                                       56

   65

of bonds by Community Facilities Districts which can be formed by a variety of
local government agencies, including school districts. These districts, known as
"Mello-Roos" districts, can have flexible boundaries and the tax imposed to
repay the bonds can be based on property use, acreage, population density or
other factors.

OTHER LEGISLATION

      California legislation adopted in 1989 provides that school districts
which currently lease any building which does not meet the prescribed structural
standards must have replaced nonconforming buildings with conforming ones by
September 1, 1990. However, any district has the right to request a one-time
waiver for a maximum of three years upon presentation of satisfactory evidence
to the State Allocation Board that the district is proceeding in a timely
fashion with a program that will eliminate the need for the nonconforming
facilities within that time period. The State has authorized districts to renew
these waivers through 2000. Modtech understands that a number of school
districts have requested and been granted such waivers. Based upon information
received by the State Allocation Board from school districts and provided to
Modtech, it is believed that there are more than 4,500 trailers currently being
used as classrooms by school districts throughout California that eventually
must be replaced with conforming facilities by these school districts.

      California has taken steps to encourage local school districts to adopt
year-round school programs to help increase the use of existing school
facilities and reduce the need for additional school facilities. School
districts requesting state funding under the School Building Lease-Purchase Law
of 1976 or the Emergency Classroom Law of 1979 discussed above must submit a
study examining the feasibility of implementing in the district a year-round
educational program that is designed to increase pupil capacity in the district
or in overcrowded high school attendance areas. The feasibility study
requirement is waived, however, if the district demonstrates that emergency or
urgent conditions exist in the district that necessitate the immediate need for
relocatable buildings. The demand for new school facilities, including
relocatable classrooms, will be adversely affected if a significant number of
California school districts implement year-round school programs. In addition, a
significant increase in the level of voluntary or mandatory busing of students
from overcrowded schools to schools with excess capacity could adversely affect
demand for new school facilities.

LITIGATION

      Modtech from time to time is involved in various lawsuits related to its
ongoing business operations, primarily collection actions or vendor disputes. In
the opinion of management, no pending lawsuit will result in any material
adverse effect upon Modtech.

ENVIRONMENTAL MATTERS

      Modtech is subject to a variety of federal, state and local governmental
regulations related to the storage, use and disposal of any hazardous materials
used by Modtech in connection with the manufacture of its products. Both the
governmental regulations and the costs associated with complying with such
regulations are subject to change in the future.

EMPLOYEES

      At September 30, 1998, Modtech had 845 employees, including 793 in
manufacturing, 6 in sales, 17 in operations and 29 in general management and
administration. Modtech's employees are not represented by a labor union, and it
has experienced no work stoppages. Modtech believes that its employee relations
are good.

PROPERTIES

      Modtech's principal executive and administrative facilities are located in
approximately 11,400 square feet of modular buildings at its primary
manufacturing facility located in Perris, California. This manufacturing
facility occupies 25 acres, with approximately 200,000 square feet of covered
production space under roof, pursuant to a lease expiring in 2014. A second
facility in Perris



                                       57

   66

occupies approximately 30 acres, with approximately 120,000 square feet of
covered production space under roof, pursuant to a lease expiring in 2014. This
second facility also includes approximately 80,000 square feet under roof used
as a metal working facility. Modtech's third plant consists of a 400,000 square
foot manufacturing facility on a 30-acre site in Lathrop, California that is
leased through 2019. The fourth plant, which was purchased in 1997, consists of
approximately 50,000 square feet of manufacturing areas on a four-acre site in
Patterson, California. Modtech's fifth plant is approximately 80,000 square feet
on a three-acre site in Glendale, Arizona, that is leased through December 1999.
Each of Modtech's current facilities, other than the Patterson and Glendale
plants, is leased from an affiliate. See "Where You Can Find More Information."

SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997

      Net sales for the six months ended June 30, 1998 increased to $75.9
million, an increase of $17.0 million, or approximately 28.8%, from $58.9
million for the six months ended June 30, 1997. The increase is attributable to
the growth in the school population, the Class Size Reduction Program, and
product line diversification.

      Gross profit was $17.2 million for the six months ended June 30, 1998, an
increase of about $6 million, or 54%, over gross profit of $11.2 million for the
same period in 1997. Gross profit as a percentage of net sales increased to
22.7% for the six months ended June 30, 1998, compared to 19.0% for the same
period in 1997. The increase was due principally to the fuller utilization of
manufacturing efficiencies.

      Selling, general and administrative expenses totaled $2.7 million for the
six months ended June 30, 1998, representing an increase of $559,000 in selling,
general and administrative expenses incurred for the six months ended June 30,
1997. The increase is primarily due to the increase in sales expense, as well as
the increase in the number of employees. As a percentage of sales, selling,
general, and administrative expenses for the six months ended June 30, 1998 was
3.6%. The percentage was 3.7% for the same period in 1997.

      Due to a higher cash balance and reduced line of credit borrowing, the six
months ended June 30, 1998 reflects net interest income of $389,000, compared to
net interest expense of $549,000 for the same period in 1997, a favorable
increase of $938,000, or 170.9%.

      On March 20, 1998, Modtech purchased an 80% interest in Trac Modular
Manufacturing, Inc. ("Trac"). The purchase price approximated the fair value of
net assets on the purchase date. Trac is based in Glendale, Arizona. The
financial activity for this subsidiary has been included in Modtech's financial
statements for the second quarter of 1998.

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

      Net sales for the year ended December 31, 1997 increased to $134.0
million, an increase of $84.1 million, or approximately 169%, from $49.9 million
in 1996. The increase in 1997 was due principally to the continuing amelioration
of the State of California budget deficit and the implementation during the year
of the Class Size Reduction Program for kindergarten through third grade classes
in California's public elementary schools.

      For the year ended December 31, 1997, gross profit was $26.7 million, an
increase of $19.4 million, or approximately 266%, over 1996 gross profit of $7.3
million. Gross profit percentage of net sales increased to 19.9% in 1997 from
14.5% in 1996. The increase in gross profit as a percentage of net sales was
primarily attributable to the increased volume, utilization of a previously idle
facility, and the realization of manufacturing efficiencies.

      In 1997, selling, general and administrative expenses increased to $5.2
million from $2.3 million, due to increases in the number of employees and an
increase in selling costs. However, as a percentage of net sales, selling,
general and administrative expenses decreased to 3.8% in 1997 from 4.7% in 1996.

      Due to increased volume and average borrowings outstanding, net interest
expense increased from $422,000 in 1996 to $909,000 for 1997.

      Income tax expense was $7.7 million for the year ended December 31, 1997,
compared to $208,000 for 1996. Modtech's effective tax rate increased to 37.2%
for the year ended December 31, 1997 from 4.6% for the year ended December 31,
1996. The effective tax rate in both periods was positively impacted by the
utilization for federal income tax purposes of net operating loss carryforwards
generated in prior years.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

      Net sales for the year ended December 31, 1996 increased to $49.9 million,
an increase of $30.5 million, or approximately 157% from $19.4 million in 1995.
The increase in 1996 was due principally to the amelioration of the State of
California budget deficit and the implementation during the year of the Class
Size Reduction Program for kindergarten through third grade classes in
California's public elementary schools.

      For the year ended December 31, 1996, gross profit was $7.3 million, an
increase of $4.3 million, or approximately 143%, over 1995 gross profit of 3.0
million. However, as a percentage of net sales, gross profit declined to 14.5%
in 1996, from 15.4% in 1995. The decline of gross profit as a percentage of net
sales was primarily attributable to a change in product mix as Modtech focused
its resources on manufacturing more standardized classrooms which could be sold
in greater numbers.

      In 1996, selling, general and administrative expenses increased to $2.3
million from $1.6 million, due to increases in the number of employees and an
increase in selling costs. However, because net sales increased substantially
during the year, selling, general and administrative expenses as a percentage of
net sales decreased to 4.7% in 1996 from 8.3% in 1995.

      For the year ended December 31, 1996, net interest expense increased by
$35,000, from $387,000 in 1995 to $422,000 in 1996, due to slightly higher
borrowings to finance growing levels of accounts receivables and
work-in-progress inventories attributable to the large 1996 increase in net
sales.



                                       60

   69


      The provision for income taxes was $208,000 for the year ended December
31, 1996, compared to $19,000 for the year ended December 31, 1995. Modtech's
effective tax rate increased to 4.6% for the year ended December 31, 1996, from
1.9% for the year ended December 31, 1995, due to differences between financial
and tax accounting treatment of certain items, primarily accrued liabilities.
The effective tax rate in both periods was positively impacted by the
utilization for federal income tax purposes of net operating loss carryforwards
generated in prior years.

INFLATION

      Modtech does not believe that inflation had a material effect on its
result of operations during the past two years. However, there can be no
assurance that Modtech's business will not be affected by inflation in the
future.

LIQUIDITY AND CAPITAL RESOURCES

      To date, Modtech has generated cash to meet its needs from operations,
bank borrowings and public offerings. At June 30, 1998, Modtech had $25,426,000
in cash. Most of Modtech's cash reserves will be used to partially pay the cash
portion of the Merger Consideration. During the six months ended June 30, 1998,
Modtech provided about $17,000,000 in cash from operating activities.

      Modtech has a revolving loan facility that expires in September 2000.
Modtech is entitled to borrow from time to time up to $20,000,000, with actual
borrowings limited to specified percentages of eligible accounts receivables,
equipment and inventories. On June 30, 1998, no amounts were outstanding under
this loan.

      Holdings is currently in negotiations for a new credit facility to be
effective upon the closing of the Mergers. Modtech and SPI will be co-borrowers
under the credit facility, which will replace both companies' existing credit
facilities. The borrowings from the new credit facility will be used to pay the
balance of the cash portion of the Merger, transaction expenses of the Mergers,
and fund working capital needs.

      Management believes Modtech's existing product lines and manufacturing
capacity will enable it to generate sufficient cash through operations,
supplemented by periodic use of Holdings anticipated bank line of credit, to
finance its business at current levels over the next 12 months. Additional cash
resources may be required, if Modtech is able to expand its business beyond
current levels. For example, it will be necessary for Modtech to construct or
acquire additional manufacturing facilities in order for it to compete
effectively in new market areas or states which are beyond a 300-mile radius
from one of its production facilities. The construction or acquisition of new
facilities would require significant additional capital. For these reasons,
among others, Modtech may need additional debt or equity financing in the
future. There can be, however, no assurance that Modtech will be successful in
obtaining such additional financing, or that any such financing will be
available on terms acceptable to it.

NEW ACCOUNTING PRONOUNCEMENTS

      In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS 130"). SFAS 130 establishes standards for the reporting and
display of comprehensive income and its components (revenues, expenses, gains
and losses) in a full set of general-purpose financial statements. SFAS 130
requires all items that are required to be recognized under accounting standards
as components of comprehensive income to be reported in a financial statement
that is displayed with the same prominence as other financial statements. SFAS
130 does not require a specific format for that financial statement but requires
that an enterprise display an amount representing total comprehensive income for
the period covered by that financial statement. SFAS 130 requires an enterprise
to (a) classify items of other comprehensive income by their nature in a
financial statement and (b) display the accumulated balance of other
comprehensive income separately from retained earnings and additional paid-in
capital



                                       61

   70

in the equity section of a statement of financial position. SFAS 130 is
effective for fiscal years beginning after December 15, 1997. Management has
determined the adoption of SFAS 130 will not have a material impact on Modtech's
combined financial position or results of operations.

      In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"). SFAS 131 establishes standards for public business enterprises to
report information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to stockholders. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. This statement supersedes FASB Statement
No. 14, "Financial Reporting for Segments of a Business Enterprise," but retains
the requirement to report information about major customers. It amends FASB
Statement No. 94, "Consolidation of All Majority-Owned Subsidiaries," to remove
the special disclosure requirements for previously unconsolidated subsidiaries.
SFAS 131 requires, among other items, that a public business enterprise report a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets, information about the revenues derived from the enterprise's
products or services, and major customers. SFAS 131 also requires that the
enterprise report descriptive information about the way that the operating
segments were determined and the products and services provided by the operating
segments. SFAS 131 is effective for financial statements for periods beginning
after December 15, 1997. In the initial year of application, comparative
information for earlier years is to be restated. SFAS 131 need not be applied to
interim financial statements in the initial year of its application, but
comparative information for interim periods in the initial year of application
is to be reported in financial statements for interim periods in the second year
of application. Management has not determined whether the adoption of SFAS 131
will have a material impact on Modtech's segment reporting.

      In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits" ("SFAS 132"). SFAS 132 revises employers' disclosures
about pension and other postretirement benefit plans. It does not change the
measurement or recognition of those plans. SFAS 132 is effective for fiscal
years beginning after December 15, 1997. SFAS 132, requiring only additional
information disclosures, is effective for Modtech's fiscal year ending December
31, 1998.

      In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and hedging activities. SFAS 133 is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999. Application of SFAS 133 is not
expected to have a material impact on the Company's financial position, results
of operations or liquidity.

YEAR 2000

      The "year 2000" issue concerns the potential exposures related to the
automated generation of business and financial misinformation resulting from the
application of computer programs which have been written using two digits,
rather than four, to define the applicable year of business transactions.
Modtech is in the process of correcting this defect in its program, and it
expects the defect will be corrected without material cost before the year 2000.
Modtech's customers, suppliers and service providers may use computer programs
which are not "year 2000" compliant. To the extent this defect is not corrected,
it could adversely affect Modtech's operations, such as the receipt of supplies,
services, purchase orders and payments of account receivable.

                               THE BUSINESS OF SPI

GENERAL

      SPI is a leading designer, manufacturer and wholesaler of commercial and
light industrial modular buildings in the United States. Through its four
manufacturing plants, SPI designs and builds modular buildings to customer
specifications for a wide array of uses, including governmental, healthcare,
educational, airport and correctional facilities; office and retail space;
daycare centers; libraries; churches; construction trailers; golf clubhouses;
police stations; convenience stores; fast food restaurants; and sales offices.

      SPI's single-unit modular buildings are typically 720 square feet in size,
while multi-unit modular buildings range in size from 1,440 square feet to
50,000 square feet and may consist of multiple stories. The price at which SPI's
modular buildings are sold to dealers ranges from $10,000 to $25,000 per module.
SPI's modular buildings serve as temporary, semi-permanent and permanent
facilities and can function as free standing buildings or additions to existing
structures.

      SPI conducts its business through three operating subsidiaries, SPI
Manufacturing, Inc., Rosewood Enterprises, Inc. and Office Master of Texas,
Inc.

INDUSTRY OVERVIEW

      According to data compiled by Automated Builder, a leading industry trade
publication, the nonresidential modular construction market, including SPI, had
approximately $350 million in annual revenues in 1997, and an 8% growth rate is
expected for 1998. Automated Builder estimates that the five largest
nonresidential modular building manufacturers, which includes SPI, accounted for
sales of approximately $177 million during 1997, while the remaining 22
manufacturers reported by Automated Builder generated approximately $173 million
of sales during the same period. SPI's pro forma consolidated net sales for the
year ended December 31, 1997 were $80.5 million.

      Much of the growth in the nonresidential modular market has resulted from
the widespread acceptance of modular structures as an alternative to traditional
site construction and the increasing number of applications for modular
buildings across a broad spectrum of industries.

      Because modular buildings are constructed in a factory using an assembly
line process, construction is typically not subject to the delays caused by
weather and site conditions. Modular buildings can, therefore, generally be
built faster than conventional buildings, at a lower cost and with more
consistent quality. Modular buildings can generally be relocated more easily to
meet the changing needs of end users and be quickly joined to other modular
buildings to meet increased space requirements.

DISTRIBUTION AND MARKETING

      SPI sells its modular buildings to users through a network of sales and
leasing companies to a wide range of end users. SPI's dealers include national
dealers such as GE Capital Modular Space and Williams Scotsman, and multiple
regional and local dealers. Management believes that larger dealers are becoming
increasingly more inclined to do business with fewer manufacturers and to place
their orders with manufacturers who have a history of consistent performance.
Certain dealers, such as GE Capital Modular Space, have developed stringent
quality control programs for the modular buildings they distribute. Management
believes SPI's products currently meet or exceed existing dealer quality control
standards.

      Certain states require SPI's dealers to be licensed to sell or lease SPI's
products. Historically, these dealers have had sufficient capital resources to
support the purchase of modular structures and the maintenance of the structures
retained in their lease fleets. Typically, dealers arrange for, and bear the
cost of, transporting and installing structures purchased from SPI.



                                       64

   73

      Because of its strong dealer relationships, SPI does not maintain an
extensive internal sales force. Instead, SPI maintains an internal marketing and
estimating staff whose primary responsibility is to maintain contact with the
dealer community and to respond to requests from dealers for price quotations
("RFQs") for production of modular buildings for end-users. As a preferred
supplier to many of its dealers, it is common for SPI to receive RFQs from a
number of dealers for the same end-user. SPI does not intend to change its
distribution methods as a result of the Mergers.

      In the past, the majority of SPI's business has been in California and
Nevada, with some distribution in Arizona, New Mexico, Utah and Colorado. The
February 1998 acquisition of Office Master expanded SPI's markets to include
Texas and contiguous states in the South and Southwest. The April 1998
acquisition of Rosewood further strengthened SPI's markets and increased SPI's
market share in Arizona, Utah, Colorado, Nevada and New Mexico. Typically, SPI
does not seek to distribute its product beyond a radius of approximately 400
miles from each manufacturing facility due to increased transportation costs.

DESIGN AND ENGINEERING

      The modular buildings manufactured by SPI are typically planned and
designed by company engineers using computer aided design technology. This
allows SPI to produce complete cost data and renderings for most of the modular
buildings manufactured by SPI. SPI uses a relational database system which
compiles pricing information, thereby eliminating the time-consuming process of
pricing modular buildings on a component-by-component basis. The system also
enables SPI to rapidly design modular buildings and to respond quickly to dealer
RFQs, while pricing projects in a manner that helps SPI achieve desired profit
margins. SPI employs a staff of engineers and draftsmen to enable SPI to respond
quickly to dealer and end-user needs at each of its manufacturing facilities.

      SPI's engineering department develops engineering design and construction
drawings to fulfill dealer and end-user order requirements. The engineering
department ensures that the order, the drawings and the RFQ are in conformity.
Change orders are developed to correct any discrepancies and to address any
changes after the order is received. The project is then engineered to meet
applicable building code requirements, job specific characteristics and customer
specifications. The construction drawings are forwarded to the manufacturing
plant and become the basis for the manufacture of each modular building.

MANUFACTURING AND PRODUCTION

      SPI operates four manufacturing facilities, two in Southern California
(Rancho Cucamonga and Ontario), one in Glen Rose, Texas, which is located
outside the Dallas-Fort Worth metropolitan area, and one in Phoenix, Arizona.
Each of SPI's manufacturing facilities is designed to allow for the production
of either single or multi-unit modular buildings.

      SPI's modular buildings are produced by a continuous flow assembly line
process. In each of SPI's manufacturing facilities, multiple structures are
assembled simultaneously at various stations along the assembly line. Depending
upon the complexity of the design for a particular modular building, the average
construction time from receipt of the order to shipment ranges from 30 to 45
days. Once construction of a typical modular building commences, the building
can be completed in as few as seven to nine days.

BACKLOG

      SPI manufactures modular structures for sale to dealers only after an
order has been received. As of December 31, 1997, SPI's backlog, including
backlog for the Office Master and Rosewood operations, was approximately $7.0
million. As of June 30, 1998, SPI's backlog was approximately $13.7 million. The
increase in backlog at June 30, 1998 is primarily a function of the seasonality
of SPI's business. Only contracts which are accompanied by customer purchase
orders are included in SPI's backlog calculations. Due to the



                                       65

   74

short order to completion cycle which is required by SPI's customers and which
is prevalent in the commercial modular building industry, the backlog as of any
particular date may not be representative of actual sales for any succeeding
period.

WARRANTIES

      The standard contractual warranty for SPI's modular buildings is a limited
one year warranty from the date of manufacture which covers workmanship and
materials. In addition, certain components included in SPI's modular buildings
carry additional warranty protection offered by the manufacturer of those
components. Occasionally, SPI contracts with third parties to provide warranty
service when the modular building is located a significant distance from any of
SPI's manufacturing facilities. Management believes SPI's warranty costs have
historically been lower than industry averages. Warranty costs have not been
material in the past.

SUPPLIERS

      SPI believes that the materials and key components used in the
manufacturing of its modular buildings are readily available at competitive
prices from multiple sources, including local, regional and national suppliers.
SPI has supply contracts with a number of these suppliers. In the past, SPI has
been able to pass along to its customers all or a portion of the effects of
price increases by increasing the selling prices of its modular buildings.

COMPETITION

      The nonresidential modular building industry is highly competitive. With
respect to highly customized modular buildings, the main competitive factor is
the ability to meet end user requirements in a timely manner, while price is the
main competitive factor for less customized structures. Because the cost of
transporting completed modular buildings is substantial, most manufacturers
limit their distribution to dealers located within a 400-mile radius of their
manufacturing facility. As a result, the nonresidential modular building
industry is highly fragmented and is composed primarily of small,
regionally-based private companies maintaining a single manufacturing facility.
SPI's main competitors include Modular Structures International, Pace Setter,
Walden Structures, International Structures, Miller Building Systems, Indicom
Building Systems and several other regional manufacturers.

REGULATORY MATTERS

      SPI's modular buildings are manufactured and installed in accordance with
state building codes or building codes of local regulatory agencies. Many states
have adopted additional codes that apply specifically to the design and
manufacture of factory-built buildings, such as those manufactured by SPI. These
regulations, which vary from state to state, apply for the state that the
factory-built structure is installed regardless of where it was manufactured.

      Obtaining state approvals for the structural portions of a manufactured
building is the responsibility of the manufacturer. SPI works closely with
various regulatory agencies in order to facilitate the approval process and
reduce the chance of regulatory delays. To expedite the state approval process,
SPI has on file with regulatory agencies in various states pre-approved
engineering and structural drawings, as well as plans for electrical, plumbing
and lighting systems.

      Most states require dealers to be licensed in order to sell or lease
factory-built buildings. The dealer or the owner is responsible for all on-site
required approvals and permits. Additionally, certain states require a
contractor's license from entities involved in the manufacture of modular
buildings, the construction of the foundation, building installation, and other
on-site work.

PROPERTIES

      SPI's principal executive and administrative facilities are located in
approximately 3,000 square feet of office space at its manufacturing facility in
Rancho Cucamonga, California. This manufacturing facility occupies six acres,
with approximately 60,000 square feet of manufacturing space. A second facility
in Ontario, California occupies approximately



                                       66

   75

seven acres, with approximately 3,300 square feet of office space and
approximately 50,000 square feet of manufacturing space. SPI's third facility
consists of approximately 80,000 square feet of manufacturing space and
approximately 2,880 square feet of office space on a 20-acre site in Glen Rose,
Texas. The fourth facility consists of approximately 80,000 square feet of
manufacturing space and approximately 6,600 square feet of office space on a
20-acre site in Phoenix, Arizona.

      SPI presently leases all of its operating facilities. The lease for the
Rancho Cucamonga facility expires March 31, 2002, and provides for two five-year
extensions thereafter; the lease for the Ontario facility expires January 31,
2002, and provides for one five-year extension thereafter; the lease for the
Glen Rose facility expires January 31, 2008; and the lease for the Phoenix
facility expires August 28, 2002, and provides for one five-year extension
thereafter. In addition to the operating facilities described above, SPI also
leases, under short-term leases, approximately two acres of land on properties
adjacent to the Phoenix facility. SPI believes that its existing facilities are
well-maintained and in good operating condition and will meet the requirements
for its immediately foreseeable business needs.

      The Phoenix facility leased by SPI is located within a 25-square-mile area
listed by the Arizona Department of Environmental Quality on the state priority
list for contaminated sites. According to a recent environmental site assessment
report pertaining to the Phoenix facility and commissioned by SPI, neither SPI
nor the prior operators or owners of the property have been identified as
potentially responsible parties at this site. Additionally, the environmental
site assessment report identifies no historical activity on the property leased
by SPI that was likely to have been a source of the contaminants at the site.

EMPLOYEES

      As of October 1, 1998, SPI had approximately 550 employees, consisting of
approximately 190 in California and 360 at its other facilities. Of SPI's total
employees, approximately 9 are management level employees, 475 are manufacturing
employees, 17 are employed in design and engineering positions and 49 are
employed in administrative, sales and clerical positions. SPI's employees are
not represented by a labor union or other collective bargaining unit. SPI
considers its relations with its employees to be satisfactory.

LITIGATION

      SPI is, from time to time, a party to litigation arising in the normal
course of its business. SPI is not involved in any pending or threatened legal
proceeding which SPI believes could reasonably be expected to have a material
adverse effect on SPI's financial position, results of operations and business
prospects.

- ----------

(A)   The results of operations of SPI for the fiscal year ended March 31, 1998
      and thereafter are not comparable to those of prior periods due to the
      application of purchase accounting upon the acquisition of SPI by
      management and an investor group in March 1997.

(B)   SPI's historical presentation and allocation of expenses is not consistent
      with the presentation of Modtech's gross profit. As such, SPI has adjusted
      its pro forma gross profit calculation elsewhere in this Joint Proxy
      Statement/Prospectus to conform with Modtech's presentation. As adjusted
      to give effect to Modtech's presentation, the gross profit would be 20.5%
      for the fiscal year ended March 31, 1998.

THREE MONTHS ENDED JUNE 30, 1998 COMPARED TO THE THREE MONTHS ENDED JUNE 30,
1997

      Net Sales. Net sales increased $11.1 million, or 112.7%, to $20.9 million
for the three-month period ended June 30, 1998 from $9.8 million for the
three-month period ended June 30, 1997. The growth in net sales for the 1998
period was the result of the inclusion of sales from Office Master, acquired in
the previous quarter, and of sales from Rosewood, acquired near the end of April
1998, for the last two months of the 1998 period.



                                       68

   77

      Gross Profit. Gross profit increased $2.0 million, or 91.8%, to $4.3
million for the three-month period ended June 30, 1998 from $2.3 million for the
three-month period ended June 30, 1997. The increase in gross profit was a
result of the increased net sales. The gross profit margin for the three months
ended June 30, 1998 was 20.7%, compared to 23.0% in the three months ended June
30, 1997. The decrease in gross profit margin for SPI was a result of lower
margins due to the higher direct labor costs of Office Master and Rosewood.

      Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased $684,000, or 137.1%, to $1.2 million in the
quarter ended June 30, 1998 from $499,000 in the quarter ended June 30, 1997.
Selling and administrative expenses as a percentage of net sales for the three
months ended June 30, 1998 increased to 5.6%, as compared to 5.1% for the three
months ended June 30, 1997. The increase in selling and administrative expenses
was primarily due to increased senior management and administrative staff to
accommodate growth and acquisitions, and to the inclusion of selling and
administrative expenses of the acquired companies.

      Management and Monitoring Fees. Pursuant to the management agreement with
KRG, SPI paid a management fee of $75,000 for the three months ended June 30,
1998, as compared with $50,000 for the three months ended June 30, 1997. An
additional $9,000 in monitoring fees were paid pursuant to an agreement with the
fund managers of certain of SPI's equity investors for the three months ended
June 30, 1998, as compared to $6,000 for the three months ended June 30, 1997.

      Depreciation and Amortization. Depreciation and amortization increased
$361,000, or 117.6%, to $667,000 for the three months ended June 30, 1998 from
$306,000 for the three months ended June 30, 1997. The increase was primarily
attributable to the amortization of goodwill, and consulting and non-compete
agreements arising from the acquisitions.


      Interest Income (Expense), Net. Net interest expense increased $453,000,
or 118.6%, to $835,000 for the three months ended June 30, 1998 from $382,000
for the three months ended June 30, 1997. The increase in interest expense was
principally the result of the use of senior and subordinated debt to fund the
Office Master and Rosewood acquisitions during 1998. Interest income was
immaterial in both periods.

      Net Income. Net income increased $438,000, or 75.4%, to $1.0 million for
the three months ended June 30, 1998 from $581,000 for the three months ended
June 30, 1997. Net income, as a percentage of net sales was 4.9%, as compared to
5.9% for the three-month period ended June 30, 1997. The increase in net income
was primarily related to the increased net sales. The decrease in net income as
a percentage of net sales reflects the effect of lower gross profit margins for
the acquisitions.

FISCAL YEAR ENDED MARCH 31, 1998 COMPARED TO THE FISCAL YEAR ENDED JANUARY 31,
1997

      Following the acquisition of SPI by management and an investor group in
March 1997, SPI adopted a March 31, fiscal year end, which first ended March 31,
1998. The Office Master acquisition was completed in February 1998.

      Net Sales. Net sales increased to $42.2 million in the year ended March
31, 1998 from $24.1 million in the year ended January 31, 1997, an increase of
$18.1 million, or 74.9%. Net sales increased as a result of the increase in
product demand from SPI's dealers. The addition of production capacity in
California in August 1997 contributed $8.3 million, or 45.7% of the increase and
the inclusion of Office Master for the last month of 1998 contributed $1.1
million, or 6.1% of the increase. See "The Business of SPI."

      Gross Profit. The major components of cost of sales are materials and to a
lesser extent, direct labor and overhead costs. SPI's gross profit increased to
$9.7 million in the year ended March 31, 1998 from $5.1 million in the year
ended January 31, 1997, an increase of $4.6 million, or 90.2%. As a percentage



                                       69

   78

of net sales, gross profit increased to 23.0% in the year ended March 31, 1998
from 21.1% in the year ended January 31, 1997. The increase in gross profit is
primarily the result of a reduction in raw material costs as a percent of net
sales, as SPI benefitted from volume purchasing discounts, partially offset by
an increase in overhead costs associated with the addition of the new Office
Master manufacturing facility.

      Selling, General and Administrative Expenses. Selling, general and
administrative expenses include executive salaries, group insurance premiums,
legal and accounting fees and various other overhead costs. Selling and
administrative expenses increased to $2.7 million in the year ended March 31,
1998 from $1.6 million in the year ended January 31, 1997, an increase of $1.1
million, or 68.8%. The addition of senior management and administrative staff to
accommodate growth, the completed Office Master acquisition, and the Rosewood
acquisition in progress, contributed to an increase of $568,000 in salaries and
wages, or 45.5% of the increase. As a percent of net sales, selling and
administrative expenses decreased to 6.3% in the year ended March 31, 1998 from
6.8% in the year ended January 31, 1997. This decrease was primarily due to the
significant growth in net sales.

      Management and Monitoring Fees. Management and monitoring fees were
incurred in connection with the financing of the management buyout of SPI and
SPI's acquisition of Office Master following the buyout. Pursuant to the
management agreement with KRG, SPI paid a management fee of $200,000 in the
fiscal year ended March 31, 1998. An additional $25,000 in monitoring fees were
paid pursuant to an agreement with the fund managers of certain of SPI's equity
investors. During the fiscal year ended March 31, 1998, SPI capitalized a total
of $350,000 in transaction closing fees in conjunction with the SPI management
buyout and the subsequent acquisition of Office Master.

      Depreciation and Amortization. Depreciation and amortization increased to
$1.8 million in the year ended March 31, 1998 from $78,000 in the year ended
January 31, 1997, an increase of $1.7 million, or 2,144.9%. The increase was
primarily attributable to the amortization of goodwill, and consulting and
non-compete agreements arising from the management buyout of SPI and subsequent
acquisition of Office Master by SPI. Depreciation expense increased primarily
due to the addition of fixed assets as a result of these acquisitions which both
occurred during the fiscal year ended March 31, 1998.

      Interest Income (Expense), Net. Net interest expense increased to a net
interest expense of $1.4 million in the year ended March 31, 1998 from a net
interest income of $0.1 million for the year ended January 31, 1997. The
increase in interest expense was principally the result of the use of senior and
subordinated debt to fund the management buyout of SPI in March 1997 and SPI's
subsequent acquisition of Office Master during the fiscal year ended March 31,
1998.

      Other Income and Expense. Other income and expense increased to a net
income of $36,000 in the fiscal year ended March 31, 1998 from a net other
expense of $6,000 in the fiscal year ended January 31, 1997. The net other
income in fiscal 1998 was entirely due to miscellaneous income. In the prior
fiscal year, the net other expense was due to penalties and interest on income
taxes payable by the former owners of SPI prior to the management buyout in the
amount of $117,000, partially offset by miscellaneous income totaling $111,000
primarily from a gain on sale of fixed assets.

      Net Income. Net income increased $77,000, or 3.8%, to $2.1 million for the
fiscal year ended March 31, 1998 from $2.0 million for the fiscal year ended
January 31, 1997. Net income as a percentage of net sales was 4.9%, as compared
to 8.5% for the fiscal year ended January 31, 1997. The increase in net income
reflects the increase in gross profit, offset by the increase in operating
expenses and provision for income taxes and the increase in net interest
expense.

   79

FISCAL YEAR ENDED JANUARY 31, 1997 COMPARED TO THE FISCAL YEAR ENDED JANUARY 31,
1996

      Net Sales. Net sales increased to $24.1 million in the year ended January
31, 1997 from $13.4 million in the year ended January 31, 1996, an increase of
$10.7 million, or 79.6%. Net sales increased as a result of an increase in
product demand by SPI's dealers. In order to meet the increasing product
demands, SPI moved to its current facility in Rancho Cucamonga, California in
late 1995.

      Gross Profit. The major components of cost of sales are materials and, to
a lesser extent, direct labor and overhead costs. SPI's gross profit increased
to $5.1 million in the year ended January 31, 1997 from $2.9 million in the year
ended January 31, 1996, an increase of $2.2 million, or 75.9%. Gross profit as a
percentage of net sales decreased to 21.1% in the fiscal year ended January 31,
1997 from 21.5% in the fiscal year ended January 31, 1996. This decrease was
primarily the result of higher direct labor and overhead costs.

      Selling, General and Administrative Expenses. Selling, general and
administrative expenses include executive salaries, group insurance premiums,
legal and accounting fees and various other overhead costs. Selling and
administrative expenses decreased to $1.6 million in the year ended January 31,
1997, from $2.6 million in the year ended January 31, 1996, a decrease of $1.0
million, or 62.5%. Selling and administrative expenses decreased as a percent of
net sales to 6.8% from 19.4% in the year ended January 31, 1996. Selling and
administrative expenses decreased primarily due to lower bonuses paid to
executive management of SPI in the year ended January 31, 1997. Other selling
and administrative expenses also decreased in the year ended January 31, 1997,
including sales salaries, automobile and travel expenses, outside services and
legal and accounting fees.

      Depreciation and Amortization. Depreciation and amortization increased to
$78,000 in the year ended January 31, 1997 from $49,000 in the year ended
January 31, 1996, an increase of $29,000, or 59.2%. Depreciation and
amortization increased as a result of a full year of depreciation in fiscal 1997
from fixed assets acquired late in fiscal 1996 in connection with the move to
the Rancho Cucamonga facility. As a percentage of net sales, depreciation and
amortization decreased to 0.3% in the year ended January 31, 1997 from 0.4% in
the in the year ended January 31, 1996, primarily due to the increase in net
sales.

      Interest Income (Expense), Net. Net interest income decreased to $78,000
in the year ended January 31, 1997 from $80,000 in the year ended January 31,
1996. The decrease in net interest income was a result of the substantial growth
in the business requiring the use of available cash.

      Other Income and Expense. Other income of $34,000 in the fiscal year ended
January 31, 1996 was replaced by a net expense of $6,000 in the fiscal year
ended January 31, 1997. The net expense in fiscal 1997 resulted primarily from
penalties and interest on income taxes payable by the former owners of SPI in
the amount of $117,000, partially offset by miscellaneous income totaling
$111,000 primarily from a gain on sale of fixed assets.

      Net Income. Net income increased $1.8 million to $2.0 million for the
fiscal year ended January 31, 1997 from $203,000 for the fiscal year ended
January 31, 1996. Net income as a percentage of net sales was 8.5%, as compared
to 1.5% for the fiscal year ended January 31, 1996. The increase in net income
reflects the increase in gross profit and decrease in operating expenses, offset
by the increase in the provision for income taxes.

LIQUIDITY AND CAPITAL RESOURCES

      SPI's primary capital needs have historically been to fund (i) the working
capital requirements necessitated by its sales growth, and (ii) the acquisition
and operation of acquired companies. SPI's primary sources of financing have
been senior and subordinated debt, cash from operations and the sale of
preferred equity. SPI anticipates that its cash flows from operations and
available lines of credit to be obtained by Holdings in connection with the


                                       71

   80

Mergers will be adequate to support its operations for at least the next 12
months.

      SPI's existing credit facility will be retired upon completion of the
Mergers. A new credit facility will be entered into by Holdings upon completion
of the Mergers. The terms of the existing credit facility are described below.

      Under the terms of the existing credit facility, SPI has available the
following: (i) a secured revolving loan of up to $2.3 million; (ii) a secured
term loan of $21.9 million; and (iii) an unsecured term loan of $8.6 million.
Revolving loans under the existing credit facility bear interest at 4.00% over
the agent bank's commercial paper rate. Secured term loans under the existing
credit facility bear interest at 4.25% over the agent bank's commercial paper
rate, and unsecured term loans under the existing credit facility bear interest
at 6.25% over the agent bank's commercial paper rate. The interest rate was
9.525% on the revolving loan, 9.775% on the secured term loan and 11.775% on the
unsecured term loan at September 30, 1998. The existing credit facility also
contains certain financial covenants which require SPI to maintain a minimum
debt coverage ratio and positive net income, to refrain from capital
expenditures in excess of certain amounts and to limit the payment of dividends.
SPI is in compliance with these financial covenants and expects to continue to
be in compliance with these covenants until completion of the Mergers. A portion
of the proceeds from the new line of credit to be obtained by Holdings pursuant
to the Mergers will be used to repay and terminate the above described credit
facility.

      SPI provided net cash from operating activities of $1.4 million for the
fiscal year ended March 31, 1998, compared to net cash provided from operating
activities of $0.8 million and $0.9 million for the fiscal years ended January
31, 1997 and January 31, 1996, respectively. During the fiscal year ended March
31, 1998, net cash from operating activities resulted from adjustments to
reconcile net income to net cash, primarily depreciation and amortization,
partially offset by the decrease in income taxes payable.

      SPI invested approximately $4.1 million, $1.6 million and $0.4 million in
the fiscal years ended March 31, 1998, January 31, 1997 and January 31, 1996,
respectively. The cash used in investing activities during the fiscal year ended
March 31, 1998 was utilized primarily for capital expenditures, including the
purchase of a leasehold interest in a manufacturing facility and certain assets
from a mobile home manufacturer and the acquisition of Office Master.

      Capital expenditures other than for acquisitions were approximately
$200,000, $200,000 and $400,000 in the fiscal years ended March 31, 1998,
January 31, 1997 and January 31, 1996, respectively. SPI expects to spend
approximately $700,000 on capital expenditures for its existing operations,
primarily for the purchase of manufacturing equipment, during the fiscal year
ending March 31, 1999.

      SPI's external sources of liquidity include debt and, if required, equity
financing. During the fiscal year ended March 31, 1998, approximately $2.2
million in net borrowings was provided from SPI's existing credit facility and
$700,000 resulted from the issuance of SPI's capital stock and warrants in
connection with the asset purchase and the transactions discussed above.

YEAR 2000 COMPLIANCE

      The "year 2000" issue concerns the potential exposures related to the
automated generation of business and financial misinformation resulting from the
application of computer programs which have been written using two digits,
rather than four, to define the applicable year of business transactions. SPI
has upgraded its information system capabilities such that it does not believe
that its systems will encounter any material "year 2000" problems. SPI's
customers, suppliers and service providers may use computer programs which are
not "year 2000" compliant. To the extent this defect is not corrected, it could
adversely affect SPI's operations, such as the receipt of supplies, services,
purchase orders and payments of accounts receivable.

RECENT ACCOUNTING PRONOUNCEMENTS

      In June 1997, the FASB issued SFAS Nos. 130 and 131 "Reporting
Comprehensive Income" and "Disclosures about Segments of an Enterprise and
Related Information." SFAS No. 130 and No. 131 are effective for fiscal years
beginning after December 15, 1997, with earlier adoption permitted. SPI does not
believe that adoption of these standards will have a material effect on SPI. SPI
has, to date, reflected no items of comprehensive income in its statement of
stockholders' equity.

      In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SPI does not currently have any financial
instruments addressed by SFAS No. 133.

           UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

      The following unaudited pro forma combined condensed financial statements
are based on the historical consolidated financial statements of Modtech and
SPI, combined, and are adjusted to give effect to the Mergers. In addition, pro
forma adjustments have been made, as discussed below, for the acquisitions
consummated by SPI prior to the Mergers (the "Pre-Mergers Acquisitions").
Certain reclassifications have been made to the historical financial statements
to conform with this pro forma presentation. These statements should be read in
conjunction with such historical financial statements and notes thereto, which
are included elsewhere in this Joint Proxy Statement/Prospectus. See "Where You
Can Find More Information".

      The unaudited pro forma combined condensed statements of income for the
year ended December 31, 1997 and for the six months ended June 30, 1998 present
the results for Modtech and SPI as if the Mergers and Pre-Mergers Acquisitions
had occurred at the beginning of each period presented. The accompanying
unaudited pro forma combined condensed balance sheet as of June 30, 1998 gives
effect to the Mergers as of that date.

      The pro forma adjustments are based upon preliminary estimates,
information currently available and certain assumptions that management believes
are reasonable under the circumstances. Holdings' actual consolidated financial
statements will reflect the effects of the Mergers on and after the Closing Date
rather than the dates indicated above. The unaudited pro forma combined
condensed financial statements neither purport to represent what the combined
results of operations or financial condition actually would have been had the
Mergers, in fact, occurred on the assumed dates, nor to project the combined
results of operations and financial position for any future period.

      The SPI Merger will be accounted for by the purchase method and,
therefore, assets and liabilities of SPI will be recorded at their fair values.
The excess of the purchase cost over the fair value of net assets acquired on
the Closing Date will be recorded as goodwill. Allocations included in the pro
forma statements are based on analysis which is not yet completed. Accordingly,
the final value of the purchase price and its allocation may differ, perhaps
significantly, from the amounts included in these pro forma statements.

      The conversion of Modtech Common Stock into Holdings Common Stock and
Series A Preferred Stock will be treated as a reorganization with no change in
the recorded amount of Modtech's assets and liabilities.

      At the Closing Date, each issued and outstanding share of SPI Capital
Stock will be converted into the right to receive 1.8785 shares of Holdings
Common Stock. Each SPI stockholder may elect to receive $49.4097 per share of
SPI Capital Stock instead of shares of Holdings Common Stock and elections will
be adjusted, if necessary, to ensure that 164,735 shares of SPI Capital Stock
are converted into $8,076,133 in cash.

      At the Closing Date, each issued and outstanding share of Modtech Common
Stock will be converted into the right to receive $3.7293 and 0.8508 shares of
Holdings Common Stock. The total cash to be received by Modtech stockholders
will equal $39,923,472. Modtech stockholders will have the right to elect to
receive 388,939 shares of Holdings Series A Preferred Stock in place of Holdings
Common Stock at the same 0.8508 exchange ratio for up to 3.94% of their Modtech
Common Stock. To the extent Modtech stockholders do not elect to receive 388,939
of Holdings Series A Preferred Stock, two Modtech stockholders, Proactive
Partners, L.P. and Lagunitas Partners, will accept such shares pro rata between
them. The number of shares of Holdings Series A Preferred Stock may be adjusted
upward or downward in order to meet the minimum requirements of Section 351 of
the Internal Revenue Code.

      The total value of the common stock and stock options component of the
Merger Consideration to be received by SPI stockholders was determined using the
average closing price of Modtech Common Stock on the Nasdaq National Market for
the 10-day trading period ended October 15, 1998. The total consideration for
the transaction was $81,434,000.

Notes:

(A)   Acquisition adjustments assume the acquisitions occurred as of the
      beginning of the period presented and the application of purchase
      accounting to each of the acquisitions.

(B)   Represents the purchase accounting impact of approximately $56,000,
      $75,000 and $556,000 for SPI, Office Master and Rosewood, respectively,
      primarily for goodwill amortization, as well as approximately $118,000,
      $20,000, and $100,000, for SPI, Office Master and Rosewood, respectively,
      for amortization of covenants not to compete which were entered into in
      connection with the acquisition.

(C)   Represents interest on the increased borrowings that financed a portion of
      the purchase price of the acquisitions, and assumes payment of interest
      only on indebtedness, with no reduction in principal during the period.

(D)   Pro forma earnings per share is computed in accordance with SFAS No. 128.
      See Note 2 to the SPI Consolidated Financial Statements.

(E)   The weighted average number of shares includes actual weighted average
      number of shares outstanding as well as common stock equivalents resulting
      from options and warrants outstanding (applicable to diluted amounts
      only).

(F)   Represents an adjustment made to income tax provision as a result of the
      pro forma adjustments in order to provide income tax expense at the
      effective tax rate.

(G)   Represents reclassification of certain salaries and production-related
      depreciation expense totaling $888,000 and $203,000, respectively, from
      operating expenses to cost of goods sold in order to conform with
      Modtech's presentation.

(H)   Represents elimination of non-recurring transaction-related expenses
      related to the acquisition of SPI by management and an investor group.

(I)   The pro forma adjustments do not reflect other anticipated reductions in
      costs and expenses expected to result from the Mergers. Such anticipated
      savings would include, but not be limited to, approximately $555,000 in
      non-recurring compensation expense paid to former owners of acquired
      entities.

Notes:

(A)   Acquisition adjustments assume the acquisitions occurred as of the
      beginning of the period presented and the application of purchase
      accounting to each of the acquisitions. The SPI historical consolidated
      amounts include the operations of Office Master and Rosewood from the date
      of acquisition.

(B)   Represents the purchase accounting impact of approximately $11,000 and
      $161,000 for Office Master and Rosewood, respectively, primarily for
      goodwill amortization, as well as approximately $3,000 and $29,000 for
      Office Master and Rosewood, respectively, for amortization of covenants
      not to compete which were entered into in connection with the
      acquisitions.

(C)   Represents interest on the increased borrowings that financed a portion of
      the purchase price of the acquisitions, and assumes payment of interest
      only on indebtedness, with no reduction in principal during the period.

(D)   Pro forma earnings per share is computed in accordance with SFAS No.
      128.--See Note 2 to the Consolidated Financial Statements.

(E)   The weighted average number of shares includes actual weighted average
      number of shares outstanding, as well as common stock equivalents
      resulting from options and warrants outstanding (applicable to diluted
      amounts only).

(F)   Represents an adjustment made to income tax provision as a result of the
      pro forma adjustments in order to provide income tax expense at the
      effective tax rate.

(G)   Represents reclassification of certain salaries and production-related
      depreciation expense, totaling $441,000 and $92,000, respectively, from
      operating expense to cost of goods sold in order to conform with Modtech's
      presentation of these items.

(H)   Represents elimination of non-recurring transaction related expenses
      related to the acquisition of Office Master and Rosewood by SPI.

(I)   The pro forma adjustments do not reflect other anticipated reductions in
      costs and expenses expected to result from the Office Master and Rosewood
      acquisitions. Such anticipated savings would include, but not be limited
      to, approximately $135,000 in non-recurring compensation expense paid to
      former owners of acquired entities.

      market price of $4.725 per share as of the grant date.

                      DESCRIPTION OF HOLDINGS CAPITAL STOCK

      The authorized capital stock of Holdings consists of 25,000,000 shares of
common stock, par value $.01 per share ("Holdings Common Stock") and 5,000,000
shares of preferred stock, par value $.01 per share ("Holdings Preferred
Stock"), of which 585,000 have been designed Series A Preferred Stock ("Holdings
Series A Preferred Stock").

      The following summary of certain provisions of the Holdings Common Stock
and Holdings Series A Preferred Stock does not purport to be complete and is
subject to, and qualified in its entirety by, the provisions of applicable law
and Holdings' Certificate
of Incorporation.

VOTING RIGHTS -- COMMON STOCK

      The holders of outstanding shares of Holdings Common Stock are entitled to
one vote on all matters submitted to a vote of stockholders.

DIVIDENDS -- COMMON STOCK

      Holders of Holdings Common Stock are entitled to receive ratably such
dividends as may be declared by the Holdings Board out of funds legally
available therefor. Holdings will continue Modtech's dividend policy. Modtech
has not declared a cash dividend on Modtech Common Stock since 1990 and has no
present intention to pay a dividend.

LIQUIDATION -- COMMON STOCK

       In the event of the liquidation, dissolution or winding-up of Holdings,
holders of Holdings Common Stock are entitled to share ratably in all assets
remaining after the payment of all liabilities and the liquidation preference of
any outstanding Holdings Series A Preferred Stock.


PREFERRED STOCK

      No shares of Holdings Series A Preferred Stock are presently outstanding.
The Holdings Series A Preferred Stock will be issued as part of the Modtech
Merger Consideration. The terms of the Holdings Series A Preferred are
as follows:

      Voting Rights. The Holdings Series A Preferred Stock has no voting rights,
including, without limitation, the right to vote on the election of directors,
mergers, reorganization or a sale of all or substantially all of Holdings
assets.

      Dividend Rights. Dividends will accrue on each share of Holdings Series A
Preferred Stock at the rate of $0.40 per annum. Dividends may not be paid on
Holdings Common Stock until all accrued dividends on Holdings Series A Preferred
Stock are paid or declared and set aside for payment.

      Liquidation Preference. If Holdings is liquidated, the holders of Holdings
Series A Preferred Stock will have the right to a liquidation preference over
the holders of Holdings Common Stock in the amount of $5 per share, plus all
accrued but unpaid dividends, before any payment is made to holders of Holdings
Common Stock.

      Conversion. Subject to proportional adjustments due to stock splits,
reverse stock splits and similar transactions, each share of Holdings Series A
Preferred Stock is convertible into one share of Holdings Common Stock. Shares
of Holdings Series A Preferred Stock may be converted into Holdings Common Stock
at any time following two years after their date of issuance. Each outstanding
share of Holdings Series A Preferred Stock will automatically be converted into
Holdings Common Stock upon the fourth anniversary date of its issuance or upon a
"change in control," whichever occurs first. A "change in control" is defined as
(i) the acquisition of Holdings by another entity by means of any



                                       97

   106



transaction or series of related transactions; (ii) a sale of all or
substantially all of the assets of Holdings; (iii) the sale of capital stock
constituting 50% or more of Holdings' outstanding capital stock at the time of
sale; or (iv) any transaction or series of related transactions in which more
than 50% of the voting power of the corporation is disposed of.

      In the future, Holdings may issue one or more additional series of
Holdings Preferred Stock. The Holdings Board is authorized to determine, with
respect to each series of Holdings Preferred Stock which may be issued, the
powers, designations, preferences, and rights of the shares of such series and
the qualifications, limitations, or restrictions thereof, including any dividend
rate, redemption rights, liquidation preferences, sinking fund terms, conversion
rights, voting rights and any other preferences or special rights and
qualifications. The effect of any issuance of the additional series of Holdings
Preferred Stock upon the rights of holders of the Holdings Common Stock depends
upon the respective powers, designations, preferences, rights, qualifications,
limitations and restrictions of the shares of the additional series of Holdings
Preferred Stock as determined by the Holdings Board. Such effects might include:


- -      dilution of the voting power of the Holdings Common Stock;

- -      the further subordination of the rights of holders of Holdings Common
       Stock to share in Holdings' assets upon liquidation; and

- -      a further reduction in the amount otherwise available for payment of
       dividends on Holdings Common Stock.

ISSUANCE

      All shares of Holdings Common Stock and Holdings Series A Preferred Stock
outstanding upon completion of the Mergers will be fully paid and nonassessable.

Certificate of Incorporation and Bylaws.

 COMPARISON OF STOCKHOLDERS' RIGHTS WITH RESPECT TO HOLDINGS AND MODTECH

      Authorized Capital. The total number of authorized shares of capital stock
of Modtech is 25,000,000 shares, consisting of 20,000,000 shares of Common
Stock, and 5,000,000 shares of Preferred Stock. The authorized capital of
Holdings is 30,000,000 shares, consisting of 25,000,000 shares of Holdings
Common Stock and 5,000,000 shares of Holdings Preferred Stock, of which 585,000
have been designated Series A Preferred Stock.

      Standard of Conduct for Directors. Under Delaware law, the standards of
conduct for directors have developed through written opinions of the Delaware
courts in cases decided by them. Generally, directors of Delaware corporations
are subject to a duty of loyalty, a duty of care and a duty of full disclosure.
The duty of loyalty has been said to require directors to refrain from
self-dealing. According to the Delaware Supreme Court, the duty of care requires
"directors . . . in managing the corporate affairs . . . to use that amount of
care which ordinarily careful and prudent men would use in similar
circumstances." Later case law has established "gross negligence" as the
standard for the duty of care or liability in the process of decision-making by
directors of Delaware corporations. In addition, the duty of full disclosure
requires the full disclosure of all material facts when seeking stockholder
action.

     Under California law, the standards of conduct for directors are governed
by statute. Section 309 of the California General Corporations Law ("California
Corporations Code") requires that a director of a California corporation perform
his duties in "good faith," in a manner he believes is "in the best interests of
the corporation and its stockholders" and with the care of an "ordinarily
prudent person in a like position . . . under similar circumstances."




                                       99

      Number of Directors. Under the Modtech Bylaws, the Modtech Board is
comprised of between five and nine directors, the exact number to be fixed by
the Modtech Board or stockholders. The Modtech Board now consists of eight
directors. The Holdings Board will initially consist of seven directors. The
Holdings Bylaws provide that the Holdings Board will consist of nine directors,
which number may be increased or decreased pursuant to the Holdings Bylaws.

      Removal of Directors. Under Section 303 of the California Corporations
Code and Modtech's charter documents, Modtech's directors may be removed without
cause by the affirmative vote of a majority of the outstanding shares entitled
to vote; provided, however, that unless the entire board is removed, no director
may be removed if the votes cast against removal would be sufficient to elect
the director if voted cumulatively at an election at which the same total number
of votes were cast. Under Holdings' charter documents, Holdings stockholders may
remove directors only for cause.

      Voting Rights. Modtech stockholders have cumulative voting rights which
allows each stockholder voting at any election of directors to cast votes equal
to the number of directors to be elected multiplied by the number of shares held
by the stockholder. The ability to cumulate votes may enable minority
shareholders to elect one or more directors in situations where, absent
cumulative voting rights, they could not elect any directors. Holdings
stockholders will not have cumulative voting rights.

      Vacancy on the Board of Directors. Except for a vacancy created by the
removal of a director, vacancies on the Modtech Board may be filled by approval
of a majority of the Board. If the number of directors then in office is less
than a quorum, the vacancy may be filled by (i) the unanimous written consent of
the directors then in office, (ii) the affirmative vote of a majority of the
directors then in office, or (iii) by a sole remaining director. Vacancies on
the Modtech Board created by removal of directors may be filled only by the
affirmative vote of a majority of the shares of Modtech Common Stock. The
Holdings Bylaws provide that vacancies and any newly created directorships
resulting from any increase in the number of directors may be filled by vote of
the holders of the particular class or series of stock entitled to elect such
director at a meeting called for the purpose, or by a majority of the directors
then in office, although less than a quorum, or by a sole remaining director, in
each case elected by the particular class or series of stock entitled to elect
such directors.

      Limitation of Liability and Indemnification. Pursuant to the Delaware
Corporation Code and the Holdings Certificate of Incorporation, the liability of
directors of Holdings to Holdings or to any stockholder of Holdings for money
damages for breach of fiduciary duty has been eliminated except for:

- -      breach of the directors' duty of loyalty to Holdings or its stockholders;

- -      acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

- -      unlawful dividends or redemptions or purchases of stock; or

- -      any transaction from which the director derived an improper personal
       benefit.

      In general, the liability of officers may not be eliminated or limited
under Delaware law. The Holdings Certificate of Incorporation provides that
Holdings will indemnify its officer and directors in any proceeding, except
those in which such individual was adjudicated as liable for negligence or
misconduct in the performance of his or her duty. The Holdings Bylaws also
provide for indemnification of officers and directors of Holdings, but only to
the extent that such officer or director (a) acted in good faith and in a manner
he reasonably believed to be in or not opposed



                                       100

   109



to the best interests of Holdings (or, with respect to a criminal matter, had no
reason to believe his conduct was unlawful) and (b) was not adjudged liable to
Holdings. Under the Holdings Bylaws, the right to indemnification is subject to
a finding that the same is proper with respect to a specific proceeding, because
the officer or director involved has met the applicable standard of conduct
(described in the preceding sentence), by any of (i) a majority vote of a quorum
(consisting of directors not involved in the proceeding) of the Holdings Board,
(ii) independent legal counsel in a written opinion, or (iii) the stockholders.
The Merger Agreement also provides for the indemnification of officers and
directors. See "The Merger Agreement -- Indemnification."

      As allowed by the California Corporations Code, Modtech's Articles of
Incorporation provide that the liability of the directors of Modtech for
monetary damages shall be eliminated to the fullest extent permissible under
California law. This is intended to eliminate the personal liability of a
director for monetary damages in an action brought by or in the right of Modtech
for breach of a director's duties to Modtech or its stockholders except for
liability for acts or omissions that involve intentional misconduct or knowing
and culpable violation of law, for acts or omissions that a director believes to
be contrary to the best interests of Modtech or its stockholders or that involve
the absence of good faith on the part of the director, for any transaction from
which a director derived an improper personal benefit, for acts or omissions
that show a reckless disregard for the director's duty to Modtech or its
stockholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, or a risk
of serious injury to Modtech or its stockholders, for acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication of
the director's duty to Modtech or its stockholders, with respect to certain
contracts in which a director has a material financial interest, and for
approval of certain improper distributions to stockholders or certain loans or
guarantees. This provision does not limit or eliminate the rights of Modtech or
any shareholder to seek non-monetary relief such as an injunction or rescission
in the event of a breach of a director's duty of care.

      Modtech's Bylaws require Modtech to indemnify its officers, directors,
employees and other agents to the full extent permitted by law, including those
circumstances in which indemnification would otherwise be discretionary. In
addition, Modtech's Articles of Incorporation expressly authorize the use of
indemnification agreements and, with the approval of its stockholders, Modtech
has entered into separate indemnification agreements with each of its directors.
Modtech's Board of Directors has authorized similar indemnification agreements
for Modtech's officers. These agreements may require Modtech, among other
things, to indemnify directors and officers against certain liabilities that may
arise by reason of their status or service as directors and officers, and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified.

      Annual Stockholder Meetings. The Modtech Bylaws provide that the annual
meeting of the stockholders will be held on such dates and at such times as
shall be designated by the Modtech Board. The Holdings Bylaws provide that the
annual meeting of stockholders shall be held at such place, on such date, and at
such time as the Board of Directors shall each year fix, which date shall be
within 13 months subsequent to the later of the organization of the corporation
or the last annual meeting of stockholders.

      Special Stockholder Meetings. The Modtech Bylaws provide that a special
meeting of the stockholders may be called at any time by the Chairman of the
Board or president, or by the Board of Directors, or by one or more stockholders
holding at least 10% of the shares entitled to vote at the meeting. The Holdings
Bylaws provide that a special meeting of the stockholders may be called at any
time by the chairman of the Board, if any, or a majority of




                                       101

   110

the Board of Directors. The Holdings Bylaws do not permit the stockholders to
call a special meeting.

      Actions by Written Consent of Stockholders. Since the Modtech Articles of
Incorporation do not provide otherwise, any action that may be taken at a
stockholder's meeting of Modtech may be taken without a meeting, without prior
notice and without a vote, upon the written consent of the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a stockholder meeting at which all
shares entitled to vote were present and voted. The California Corporations Code
requires any action taken by written consent to elect Modtech directors to be
unanimous. Pursuant to Holdings' Certificate of Incorporation, any action
required or permitted to be taken by the stockholders must be effected at a duly
called annual or special meeting of stockholders and may not be effected by any
consent in writing in lieu of a meeting of such stockholders.

      Dividends and Other Distributions. Under the Delaware Corporations Code,
dividends may be paid out of the surplus of the corporation or, if there is no
surplus, out of net profits for the year in which the dividend is declared
and/or the preceding fiscal year. The California Corporations Code allows the
payment of dividends and other distributions (including redemptions) only if (1)
the amount of retained earnings immediately before the distribution equals or
exceeds the distribution, or (2) immediately after the distribution:

- -      the sum of the assets of the corporation (including goodwill, capitalized
       research and development expenses, and deferred charges) is at least
       equal to 1-1/4 times its liabilities (not including deferred taxes,
       deferred income and other credits); and

- -      the current assets of the corporation are at least equal to its current
       liabilities, or the average earnings of the corporation before taxes on
       income and before interest expense for the two preceding fiscal years was
       less than the average of the interest expense of the corporation for
       those fiscal years at least 1-1/4 times its current liabilities.


COMPARISON OF STOCKHOLDERS' RIGHTS WITH RESPECT TO HOLDINGS AND SPI

      Authorized Capital. The total number of shares of capital stock of SPI is
9,262,000, consisting of 6,000,000 shares of SPI Common Stock, 1,100,000 shares
of Series A-1 Preferred Stock, 1,000,000 shares of Series A-2 Preferred Stock,
400,000 shares of Series A-3 Preferred Stock, 155,000 shares of Series A-4
Preferred Stock, 540,000 shares of Series A-5 Preferred Stock and 67,000 shares
of Series A-6 Preferred Stock.

      Standard of Conduct for Directors. Under Colorado law, the standards of
conduct for directors have developed through written opinions of the Colorado
courts. Generally, directors of Colorado corporations are subject to a duty of
loyalty, a duty of care and a duty of full disclosure. The duty of loyalty has
been said to require directors to refrain from self-dealing. According to the
Colorado Supreme Court, the duty of care requires "directors . . . in managing
the corporate affairs . . . to use that amount of care which ordinarily careful
and prudent men would use in similar circumstances." Later case law has
established "gross negligence" as the standard for the duty of care or liability
in the process of decision-making by directors of Colorado corporations. In
addition, the duty of full disclosure requires the full disclosure of all
material facts when seeking stockholder action.

      Number of Directors. Under the SPI Bylaws, the SPI Board is comprised of
no less than one or more than nine directors, the exact number as fixed by
resolution of the SPI Board. The SPI Board now consists of six directors. The
Holdings Bylaws provide that the Holdings Board will consist of nine directors.




                                       102

   111

      Removal of Directors. Under the SPI Bylaws and Colorado law, since the SPI
Articles of Incorporation are silent, the SPI stockholders may remove one or
more directors with or without cause at any meeting of the SPI stockholders
called for that purpose. Under Holdings' charter documents, the Holdings
stockholders may remove any director from office at any time, but only for
cause.

      Vacancies on the Board of Directors. The SPI Bylaws provide that any
vacancy on the Board of Directors may be filled by the affirmative vote of a
majority of the stockholders or by the affirmative vote of a majority of the
directors remaining in office. The Holdings Bylaws provide that vacancies and
any newly created directorships resulting from any increase in the number of
directors may be filled by vote of the holders of the particular class or series
of stock entitled to elect such director at a meeting called for the purpose, or
by a majority of the directors then in office, although less than a quorum, or
by a sole remaining director, in each case elected by the particular class or
series of stock entitled to elect such directors.

      Annual Stockholder Meetings. The SPI Bylaws provide that the annual
meeting of the stockholders shall be held at a date and time fixed by resolution
of the Board of Directors or by the president in the absence of action by the
Board of Directors. The Holdings Bylaws provide that the annual meeting of
stockholders shall be held at such place, on such date, and at such time as the
Board of Directors shall each year fix, which date shall be within 13 months
subsequent to the later of the organization of the corporation or the last
annual meeting of stockholders.

      Special Stockholder Meetings. The SPI Bylaws provide that a special
meeting of the stockholders may be called at any time by the chairman of the
Board of Directors, by the president, or by resolution of the Board of
Directors. A special meeting may also be called by the holders of at least 10%
of all votes entitled to be cast on any issue proposed to be considered at the
meeting. The Holdings Bylaws provide that a special meeting of the stockholders
may be called at any time by the chairman of the Board, if any, or a majority of
the Board of Directors. The Holdings Bylaws do not permit the stockholders to
call a special meeting.

      Action by Written Consent. Under the SPI Bylaws and Colorado law, since
the SPI Articles of Incorporation are silent, any action required or permitted
to be taken at a stockholders' meeting may be taken without a meeting if all of
the stockholders entitled to vote on the action consent to such action in
writing. Pursuant to Holdings' Certificate of Incorporation, any action required
or permitted to be taken by the stockholders must be effected at a duly called
annual or special meeting of stockholders and may not be effected by any consent
in writing in lieu of a meeting of such stockholders.

      Dividends and Other Distributions. The Colorado Business Corporation Act
allows the payment of dividends and other distributions (including redemptions)
only if, after giving it effect: (i) the corporation will be able to pay its
debts as they become due in the usual course of business; or (ii) the
corporation's total assets will be equal to or more than the sum of its total
liabilities, plus the amount that would be needed, if the corporation were to be
dissolved at the time of the distribution, to satisfy the preferential rights
upon dissolution of stockholders whose preferential rights are superior to those
receiving the distribution.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Modtech, Inc.:

We have audited the accompanying balance sheets of Modtech, Inc. as of December
31, 1996 and 1997 and the related statements of income, shareholders' equity and
cash flows for each of the years in the three-year period ended December 31,
1997. In connection with our audits of the financial statements, we have also
audited the financial statement schedule as listed in the accompanying index.
These financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and financial statement schedule 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, the financial statements referred to above present fairly, in
all material respects, the financial position of Modtech, Inc. as of December
31, 1996 and 1997 and the results of its operations and its cash flows for each
of the years in the three-year period ended December 31, 1997, in conformity
with generally accepted accounting principles. Also in our opinion, the related
financial statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

                          Notes to Financial Statements

                        December 31, 1995, 1996 and 1997


(1)   DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      DESCRIPTION OF BUSINESS

      Modtech, Inc. (the Company) designs, manufactures, markets and installs
      modular relocatable classrooms.

      The Company's classrooms are sold primarily to California school
      districts. The Company also sells classrooms to the State of California
      and to leasing companies, who lease the classrooms principally to
      California school districts.

      Effective October 1, 1996, the Company acquired substantially all of the
      operating assets and assumed certain liabilities of Miller Structure, Inc.
      - California. The Company leased the manufacturing facility from 
      Miller Structure (note 18).

      USE OF ESTIMATES

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosures of contingent assets and liabilities at the date of the
      financial statements and the reported amounts of revenues and expenses
      during the reported period. Actual results could differ from those
      estimates.

      FAIR VALUE OF FINANCIAL INSTRUMENTS

      The carrying value of cash, contracts receivable and notes receivable,
      costs and estimated earnings in excess of billings on contracts, prepaid
      and other assets, accounts payable, accrued liabilities, billings in
      excess of estimated earnings on contracts and notes payable are measured
      at cost which approximates their fair value.

      CONSTRUCTION CONTRACTS

      The accompanying financial statements have been prepared using the
      percentage-of-completion method of accounting and, therefore, take into
      account the costs, estimated earnings and revenue to date on contracts not
      yet completed. Revenue recognized is that percentage of the total contract
      price that cost expended to date bears to anticipated final total cost,
      based on current estimates of costs to complete. Most contracts are
      completed within one year.

      Contract costs include all direct material and labor costs and those
      indirect costs related to contract performance, such as indirect labor,
      supplies, tools, repairs, and depreciation costs. Selling, general, and
      administrative costs are charged to expense as incurred. At the time a
      loss on a contract becomes known, the entire amount of the estimated
      ultimate loss is recognized in the financial statements.

                    Notes to Financial Statements, Continued

      The current asset, "Costs and Estimated Earnings in Excess of Billings on
      Contracts," represents revenues recognized in excess of amounts billed.
      The current liability, "Billings in Excess of Costs and Estimated Earnings
      on Contracts," represents billings in excess of revenues recognized.

      The current contra asset, "Allowance for Contract Adjustments," is
      management's estimated adjustments to contract amounts due to disputes and
      or litigation.

      Inventories are valued at the lower of cost or market. Cost is determined
      by the first-in, first-out (FIFO) method. Inventories, generally include
      only raw materials, as any work-in-process or finished goods are accounted
      for in percentage of completion allocations.

      PROPERTY AND EQUIPMENT

      Property and equipment are stated at cost. Depreciation and amortization
      is provided using the straight-line and accelerated methods over the
      following estimated useful lives:



                                              
           Leasehold improvements           15 to 31 years
           Machinery and equipment            5 to 7 years
           Trucks and automobiles             3 to 5 years
           Office equipment                   5 to 7 years


      IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF

      The Company adopted the provisions of Statement of Financial Accounting
      Standard No. 121 (SFAS No. 121), "Accounting for the Impairment of
      Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," on January
      1, 1996. This Statement requires that long-lived assets and certain
      identifiable intangibles be reviewed for impairment whenever events or
      changes in circumstances indicate that the carrying amount of an asset may
      not be recoverable. Recoverability of assets to be held and used is
      measured by a comparison of the carrying amount of an asset to future net
      cash flows expected to be generated by the asset. If such assets are
      considered to be impaired, the impairment to be recognized is measured by
      the amount by which the carrying amount of the assets exceed the fair
      value of the assets. Assets to be disposed of are reported at the lower of
      the carrying amount of fair value less costs to sell. Adoption of this
      Statement did not have a material impact on the Company's financial
      position, results of operations, or liquidity.

      STOCK OPTION PLAN

      Prior to January 1, 1996, the Company accounted for its stock option plan
      in accordance with the provisions of Accounting Principles Board (APB)
      Opinion No. 25, "Accounting for Stock Issued to Employees," and related
      interpretations. As such, compensation expense would be recorded on the
      date of grant only if the current market price of the underlying stock
      exceeded the exercise price. On January 1, 1996, the Company adopted
      Statement of Financial Accounting Standard No. 123 (SFAS No. 123),
      "Accounting for Stock-Based Compensation," which permits entities to
      recognize as expense over the vesting period the fair value of all
      stock-based awards on the date of grant. Alternatively, SFAS No. 123 also
      allows entities to continue to apply the provisions of APB Opinion No. 25
      and provide pro forma net income and pro forma earnings per share
      disclosures for employee stock option grants made in 1995 and future years
      as if the fair-value-based method defined in SFAS No. 123 had been
      applied. The Company

      has elected to continue to apply the provision of APB Opinion No. 25 and
      provide the pro forma disclosure provisions of SFAS No. 123.

      EARNINGS PER SHARE

      Effective December 31, 1997, the Company adopted Statement of Financial
      Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This
      statement replaces the previously reported primary and fully diluted
      earnings per share with basic and diluted earnings per share. Unlike
      primary earnings per share, basic earnings per share excludes any dilutive
      effects of options. Diluted earnings per share is very similar to the
      previously reported fully diluted earnings per share. All earnings per
      share amounts have been restated to conform to the SFAS No. 128
      requirements.

      TAXES ON INCOME

      Income taxes are accounted for under the asset and liability method.
      Deferred tax assets and liabilities are recognized for the future tax
      consequences attributable to differences between the financial statement
      carrying amounts of existing assets and liabilities and their respective
      tax bases and tax credit carryforwards. Deferred tax assets and
      liabilities are measured using enacted tax rates expected to apply to
      taxable income in the years in which those temporary differences are
      expected to be recovered or settled. The effect on deferred tax assets and
      liabilities of a change in tax rates is recognized in income in the period
      that includes the enactment date.

      RECLASSIFICATION

      Certain amounts in the 1995 and 1996 financial statements have been
      reclassified to conform to the 1997 presentation.

      In June 1990, the Industrial Development Authority of the County of San
      Joaquin, California issued $4,200,000 of Industrial Development Bonds. The
      net proceeds of approximately $4,000,000 were used to fund the
      construction of a manufacturing facility on leased property located in
      Lathrop, California. The Company fully utilized the bonds at December 31,
      1991. The Company has executed financing statements covering the plant and
      equipment financed, as security for repayment of the bonds. The bonds are
      secured by a $1,299,275 letter of credit, and bear interest at an initial
      rate of 6.75% and fluctuate weekly. The interest rate was 3.65% at
      December 31, 1997. The bond agreement was amended in 1997 requiring
      repayment of the balance by December 31, 1998.

      present manufacturing facility leases are with the Company's Chairman and
      partnerships composed of an officer and shareholders. All related party
      leases require monthly payments which aggregate $37,000. In connection
      with the lease at the Lathrop facility, the Company made an $83,000
      security deposit during 1990.

      In 1994, due to declines in real estate values, the Company's Chairman and
      partnerships reduced the monthly lease rates for the manufacturing
      facilities to an aggregate of $37,000. The reduced rents will continue for
      as long as real estate values remain depressed.

      using the Black Scholes option-pricing model with the following
      weighted-average assumptions; 1995 - expected dividend yield 0%, risk-free
      interest rate of 7.80%, volatility factor of 72.66%, and expected life of
      four years; 1996 - expected dividend yield 0%, risk-free interest rate of
      7.80%, volatility factor of 72.66%, and an expected life of four years;
      1997 - expected dividend yield 0%, risk-free interest rate of 7.80%,
      volatility factor of 73.06%, and an expected life of four years. The

      Pro forma net income reflects only options granted since January 1, 1995.
      Therefore, the full impact of calculating compensation cost for stock
      options under SFAS No. 123 is not reflected in the pro forma net income
      amounts presented above because compensation cost is reflected over the
      options' vesting period of four years and compensation cost for options
      granted prior to January 1, 1995 is not considered.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS

                               September 30, 1998

(1)  Management Opinion

     In the opinion of management, the condensed financial statements reflect
     all adjustments (which include only normal recurring adjustments) necessary
     to present fairly the financial position and results of operations as of
     and for the periods presented.

     The results of operations for the nine months ended September 30, 1998 are
     not necessarily indicative of the results to be expected for the full
     fiscal year.

     Certain statements in this report constitute "forward looking statements"
     within the meaning of Section 27A of the Securities Act of 1933 and Section
     21E of the Securities Exchange Act of 1934. Such forward - looking
     statements involve known and unknown risks, uncertainties and other factors
     which may cause the actual results, performance, or achievements of the
     Company to be materially different from any future results, performance, or
     achievements, expressed or implied by such forward - looking statements.

(2)  Taxes on Income

     Income taxes are accounted for under the asset and liability method.
     Deferred tax assets and liabilities are recognized for the future tax
     consequences attributable to differences between the financial statement
     carrying amounts of existing assets and liabilities and their respective
     tax bases and tax credit carryforwards. Deferred tax assets and liabilities
     are measured using enacted tax rates expected to apply to taxable income in
     the years in which those temporary differences are expected to be recovered
     or settled. The effect on deferred tax assets and liabilities of a change
     in tax rates is recognized in income in the period that includes the
     enactment date.

(3)  Earnings Per Share

     Effective December 31, 1997, the Company adopted Statement of Financial
     Accounting Standards No. 128, "Earnings per Share" (SFAS No. 128). This
     statement replaces the previously reported primary and fully diluted
     earnings per share with basic and diluted earnings per share. Unlike
     Primary earnings per share, basic earnings per share excludes any dilutive
     effects of options and convertible securities. Diluted earnings per share
     is very similar to the previously reported fully diluted earnings per
     share. All earnings per share amounts for all periods have been restated to
     conform to the SFAS No. 128 requirement.

Net sales decreased by $2,562,000 or 6.4% for the three months and increased by
$14,408,000 or 14.6% for the nine months ended September 30, 1998. The overall
increase in revenue is attributable to the growth in the school population, the
Class Size Reduction program and a diversification of our product line. The
three month decrease was primarily due to the delay by the California
Legislature in the adoption of the California state fiscal budget for
1998/1999.

Gross profit as a percentage of net sales for the three and nine months ended
September 30, 1998 increased to 23.7% and 23.0% from 21.5% and 20.0% for the
same period in 1997. The increase was due principally to the utilization of the
manufacturing facilities and the realization of manufacturing efficiencies and
product mix.

Selling, general and administrative expenses decreased for the three months
ended September 30, 1998 by $260,000 and increased for the nine months ended
September 30, 1998 by $299,000, a change of 19.1% and 8.4% respectively. The
increase is primarily due to the increase in sales expense as well as the
increase in the number of employees. As a percentage of sales, selling, general,
and administrative expenses for the three and nine months ended September 30,
are 3.0% and 3.4% for 1998. The percentages were 3.4% and 3.6% for the same
period in 1997.

Due to a higher cash balance and reduced line of credit borrowing, the nine
months ended September 30, 1998 reflects net interest income of $712,000
compared to net interest expense of $751,000 for the same period in 1997, a
favorable increase of $1,463,000 or 194.8%.

On March 20, 1998, the Company purchased an 80% interest in Trac Modular
Manufacturing, Inc (Trac). The purchase price approximated the fair value of net
assets on the purchase date. Trac is based in Glendale, Arizona. The financial
activity for this subsidiary has been included in the Company's financial
statements for the second and third quarter of 1998.

Modtech, Inc. has announced that it has entered into a definitive agreement to
purchase 100% of the equity of SPI Manufacturing, Inc. ("SPI"), a privately held
company. SPI is a leading designer, manufacturer and wholesaler of commercial
and light industrial modular buildings. The transaction is scheduled to close in
December 1998 and is subject to shareholder and regulatory approval.

The acquisition will be structured as a merger transaction whereby each of
Modtech, Inc. and SPI will become wholly owned subsidiaries of a newly formed
public holding company, Modtech Holdings. Modtech holdings will acquire SPI for
consideration consisting of approximately $8 million in cash and approximately 5
million shares of holding company common stock. Modtech Holdings will also
refinance approximately $32 million of SPI debt. The merger agreement also
provides that Modtech, Inc. shareholders will receive approximately $3.66 per
share (in the aggregate, approximately $40 million) and that all of the
outstanding Modtech, Inc. shares will be converted into Modtech Holdings common
stock (approximately 10 million shares) at an effective ratio of approximately 1
Modtech, Inc. share to 0.85 shares of Modtech Holdings. Modtech Holdings shares
will be traded on NASDAQ in replacement of the existing Modtech, Inc. shares.

SPI had pro forma consolidated net sales of approximately $80 million for the
fiscal year ended March 31, 1998, which include the results of its California
operations, the Texas operation which was acquired in February 1998 and the
Arizona operation which was acquired in April 1998.

INFLATION

In the past, the Company has not been adversely affected by inflation, because
it has been generally able to pass along to its customers increases in the costs
of labor and materials.

LIQUIDITY AND CAPITAL RESOURCES

To date, the Company has generated cash to meet its needs from operations, bank
borrowings and public offerings. At September 30, 1998, the Company had
$30,450,000 in cash. During the nine months ended September 30, 1998, the
Company provided cash in it's operating activities.

The Company has a revolving loan commitment that will expire in the year 2000.
The Company is entitled to borrow, from time to time up to $20,000,000 with
actual borrowings limited to specified percentages of eligible accounts
receivables, equipment and inventories. On September 30, 1998, no amounts were
outstanding under this loan.

During the three and nine months ended September 30, 1998,certain directors,
officers or employees exercised 14,575 and 49,575 common stock options for a
total of $41,688 and $63,738, respectively.

Management believes that the Company's existing product lines and manufacturing
capacity will enable the Company to generate sufficient cash through operations,
supplemented by periodic use of its existing bank line of credit, to finance the
Company's business at current levels over the next 12 months. Additional cash
resources may be required if the Company is able to expand its business beyond
current levels. For example, it will be necessary for the Company to construct
or acquire additional manufacturing facilities in order for the Company to
compete effectively in new market areas or states which are beyond a 300 mile
radius from one of its production facilities. The construction or acquisition of
new facilities would require significant additional capital. For these reasons,
among others, the Company may need additional debt or equity financing in the
future. There can be, however, no assurance that the Company will be successful
in obtaining such additional financing, or that any such financing will be
available on terms acceptable to the Company.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1997, the FASB issued Statement of Financial Accounting Standards No.
130, "Reporting Comprehensive Income" ("SFAS 130"). SFAS 130 establishes
standards for the reporting and display of comprehensive income and its
components (revenues, expenses, gains and losses) in a full set of
general-purpose financial statements. SFAS 130 requires all items that are
required to be


                                      F-29


   144

recognized under accounting standards as components of comprehensive income to
be reported in a financial statement that is displayed with the same prominence
as other financial statements. SFAS 130 does not require a specific format for
that financial statement but requires that an enterprise display an amount
representing total comprehensive income for the period covered by that financial
statement. SFAS 130 requires an enterprise to (a) classify items of other
comprehensive income by their nature in a financial statement and (b) display
the accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. SFAS 130 is effective for fiscal years beginning after
December 15, 1997. Management has determined the adoption of SFAS 130 will not
have a material impact on the Company's combined financial statement or results
of operations.

In June 1997, the FASB issued Statement of Financial Accounting Standards No.
131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"). SFAS 131 establishes standards for public business enterprises to
report information about operating segments in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports issued to shareholders. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. This statement supersedes FASB Statement
No. 14, "Financial Reporting for Segments of a Business Enterprise", but retains
the requirement to report information about major customers. It amends FASB
Statement No. 94, "Consolidation of All Majority-Owned Subsidiaries", to remove
the special disclosure requirements for previously unconsolidated subsidiaries.
SFAS 131 requires, among other items, that a public business enterprise report a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets, information about the revenues derived from the enterprise's
products or services, and major customers. SFAS 131 also requires that the
enterprise report descriptive information about the way that the operating
segments were determined and the products and services provided by the operating
segments. SFAS 131 is effective for financial statements for periods beginning
after December 15, 1997. In the initial year of application, comparative
information for earlier years is to be restated. SFAS 131 need not be applied to
interim financial statements in the initial year of its application, but
comparative information for interim periods in the initial year of application
is to be reported in financial statements for interim periods in the second year
of application. Management has not determined whether the adoption of SFAS 131
will have a material impact on the Company's segment reporting.

In February 1998, the FASB issued Statement of Financial Accounting Standards
No. 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits" ("SFAS 132"). SFAS 132 revises employers' disclosures about pension
and other postretirement benefit plans. It does not change the measurement or
recognition of those plans. SFAS 132 is effective for fiscal years beginning
after December 15, 1997. SFAS 132, requiring only additional information
disclosures, is effective for the Company's fiscal year ending December 31,
1998.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and hedging activities. SFAS 133 is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999. Application of SFAS 133 is not
expected to have a material impact on the Company's financial position, results
of operations or liquidity.

YEAR 2000

The Company is currently working to resolve the potential impact of the Year
2000 on the processing of date-sensitive information by the Company's
computerized information systems. The Year 2000 problem is the result of
computer programs being written using two digits (rather than four) to define
the applicable year. Any of the Company's programs that have time sensitive
software may recognize a date using "00" as the year 1900 rather than the year
2000, which could result in miscalculations or system failures.

The Company has investigated the impact of the Year 2000 problem on its
business, including the Company's operational, information and financial
systems. Based on this investigation, the Company does not expect the Year 2000
problem, including the cost of making the Company's computerized information
systems Year 2000 compliant, to have a material adverse impact on the Company's
financial position or results of operations in future periods. However, the
inability of the Company to resolve all potential Year 2000 problems in a timely
manner could have a material adverse impact on the Company.

The Company has also initiated communications with significant suppliers and
vendors on which the Company relies in an effort to determine the extent to
which the Company's business is vulnerable to the failure by these third
parties' to remediate their Year 2000 problems. While the Company had not been
informed of any material risks associated with the Year 2000 problem on these
entities, there can be no assurance that the computerized information systems of
these third parties will be Year 2000 compliant on a timely basis. The inability
of these third parties to remediate their Year 2000 problems could have a
material adverse impact on the Company.

To the extent possible, the Company will be developing and executing contingency
plans designed to allow continued operation in the event of failure of the
Company's or third parties'

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Shareholders of
  SPI Holdings, Inc.:

We have audited the accompanying consolidated balance sheets of SPI HOLDINGS,
INC. (a Colorado corporation) as of January 31, 1997, March 27, 1997 and March
31, 1998, and the related consolidated statements of income, shareholders'
equity and cash flows for the years ended January 31, 1996 and 1997, the period
from February 1, 1997 to March 27, 1997, and the year ended March 31, 1998.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated 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, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of SPI Holdings, Inc.
as of January 31, 1997, March 27, 1997 and March 31, 1998 and the results of its
operations and its cash flows for the years ended January 31, 1996 and 1997, the
period from February 1, 1997 to March 27, 1997 and the year ended March 31, 1998
in conformity with generally accepted accounting principles.

        approximately $251,000 and incurred payroll expenses of approximately
        $47,000 during the period. There were no other material activities
        during this four-day period.

        Because of the effects of purchase accounting, the accounts of the
        Predecessor are not comparable to those of the Company.

        Work-in-process consists of raw materials and labor. Overhead costs are
        not capitalized due to the short construction period, and in the opinion
        of management, are not material.

        Finished goods typically consist of structures manufactured for
        customers based upon a verbal or preliminary order but for which a
        signed purchase order was not received as of the balance sheet date.

        d.      Equipment and Leasehold Improvements

        Equipment and leasehold improvements are stated at cost. Depreciation is
        computed using straight-line and accelerated methods over the following
        estimated useful lives:

            Furniture and fixtures               Seven years
            Vehicles and equipment               One to seven years
            Leasehold improvements               Useful life or life of the
                                                 lease, whichever is shorter

        Upon retirement or disposal of depreciable assets, the cost and related
        accumulated depreciation are removed from the accounts and the resulting
        gain or loss is reflected in operations. Major renewals or betterments
        are capitalized while maintenance costs and repairs are expensed in the
        period incurred.

        e.      Revenue Recognition

        The Company recognizes revenue under the completed-contract method. In
        accounting for such contracts, income is recognized when performance is
        substantially completed and accepted.

        f.      Goodwill

         The purchase price in excess of the fair market value of net assets
         acquired for each acquisition is recorded as goodwill and amortized
         using the straight-line method over a period of 40 years. Accumulated
         amortization related to goodwill was $239,000 at March 31, 1998.

        g.      Covenants not to Compete

        Covenants not to compete entered into as part of purchase agreements are
        amortized over the term of the covenant on a straight-line basis.
        Accumulated amortization related to the covenants not to compete was
        $575,000 at March 31, 1998.

        h.      Accounting for Equity-based Compensation

        Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting
        for Stock-Based Compensation" establishes financial accounting and
        reporting standards for stock-based employee compensation plans and
        transactions in which an entity issues its equity instruments to acquire
        goods or services from non-employees. The adoption of the accounting
        methodology of SFAS No. 123 related to employees is optional, and as
        permitted under SFAS No. 123, the Company intends to continue to account
        for employee stock options using the intrinsic value methodology in
        accordance with the Accounting Principles Board Opinion No. 25; however,
        pro forma disclosures as if the Company adopted the accounting
        methodology of SFAS No. 123 are required to be presented. (see Note 13)

        i.      Use of Estimates

        The preparation of financial statements in conformity with generally
        accepted accounting principles requires management to make estimates and
        assumptions that affect the reported amounts of assets and liabilities
        and disclosure of contingent assets and liabilities at the date of the
        financial statements and reported amounts of revenues and expenses
        during the reporting period. Actual results could differ from those
        estimates.

        j.      Reclassifications

        Certain reclassifications have been made to the prior year financial
        statements in order to conform with the current year's presentation.

        k.      New Accounting Pronouncements

   
        In June 1997, the Financial Accounting Standards Board (FASB) issued
        SFAS Nos. 130 and 131 "Reporting Comprehensive Income" and "Disclosures
        about Segments of an Enterprise and Related Information." SFAS No. 130
        and No. 131 are effective for fiscal years beginning after December 15,
        1997, with earlier adoption permitted. The Company does not believe that
        adoption of these standards will have a material effect on the Company's
        financial statements. The Company has to date reflected no items of
        comprehensive income in its statement of shareholders' equity.
    

        l.      Earnings Per Share

        The Company accounts for earnings per share in accordance with SFAS No.
        128, "Earnings per Share." This Statement requires the presentation of
        both basic and diluted net income per share for financial statement
        purposes. Basic net income per share is computed by dividing income
        available to common shareholders by the weighted average number of
        common shares outstanding. Diluted net income per share includes the
        effect of the potential shares outstanding, including dilutive stock
        options using the treasury stock method.


                                      F-41

        Concurrent with the proposed merger, all outstanding shares of preferred
        stock will convert into common stock of the acquiring Company or
        redeemed for cash. (See Note 16 c.) Earnings per share is calculated
        using the weighted average number of common shares outstanding that
        would have resulted from the preferred stock conversion to common
        shares.

        The following table reconciles the components of the pro forma basic net
        income per share calculation to pro forma diluted net income per share.

        500,000 shares of convertible Series A-5 Preferred stock, 10,000
        convertible Series A-6 Preferred stock options, and 63,346 convertible
        Series A-3 Preferred stock warrants were issued subsequent to year end.
        Additionally, 62,333 shares of convertible Series A-6 Preferred stock
        and 28,416 convertible Series A-5 preferred stock options, which are
        subject to further adjustment based on the final purchase price
        calculation for Rosewood, were issued subsequent to year end. These
        subsequent equity issuances are not included in the fiscal 1998 earnings
        per common share calculation above.

3.      Receivables From Related Parties and Former Officers

        Notes receivable from related parties and accounts receivable from
        former officers represent advances to the former shareholders of the
        Predecessor during the years ended January 31, 1996 and 1997. Interest
        accrued monthly on the receivables at 6.5 percent. Pursuant to the
        acquisition of the Predecessor described in Note 1, these receivables
        were paid following the close of the transaction.

4.      Employee Benefit Plan

        The Company sponsors a defined contribution plan (the Plan) under which
        all employees who have completed one year of service are eligible to
        participate. Company contributions, if any, are determined annually by
        the board of directors from net profits or accumulated earnings and may
        not exceed 15 percent of each employee's eligible compensation, as
        defined. Vesting under the Plan is at a rate of 20 percent per year
        beginning after the second year of participation. During the year ended
        January 31, 1997, the Company made contributions to the Plan totaling
        $64,000. The Company did not make contributions to the plan during the
        year ended January 31, 1996 or the period from February 1, 1997 to March
        27, 1997. The Company accrued a contribution of $131,000 at March 31,
        1998, which was paid after year end. One of the former shareholders was
        the trustee of the Plan through March 27, 1997. The President of the
        Company and a member of the Board of Directors are currently the
        trustees.

5.      Revolving Line of Credit

        The Company maintains a working capital note with a bank which matures
        on the earlier of May 1, 2004 or whenever the Long-Term Debt is paid in
        full. As of March 31, 1998, borrowings against the line of credit
        totaled $600,000. The unused amount available under this line of credit
        was $2,751,000 as of March 31, 1998. Interest accrues at the Commercial
        Paper Rate, plus 4 percent. The weighted average interest rate for the
        year ended March 31, 1998 was 9.62 percent. The weighted average amount
        of borrowings outstanding during the year ended March 31, 1998 was
        $988,000. This line of credit is secured by a security interest which
        covers substantially all assets of the Company. This line of credit
        contains certain restrictive covenants, which, among other things,
        require the maintenance of certain financial ratios and place limits on
        other indebtedness. As of March 31, 1998, the Company was in compliance
        with all of the financial covenants in the credit agreement.

        The debt discount represents the value of warrants which were issued in
        conjunction with the notes payable. The debt is being accreted to face
        value using the effective interest method. The credit agreements also
        contain anti-dilution provisions, which require the issuance of
        additional warrants upon triggering events, such as the issuance of
        certain equity securities at issuance or exercise prices below specified
        amounts. Upon the occurrence of those triggering events, the Company
        records additional debt costs, which are amortized over the remaining
        life of the debt.

12.     Shareholders' Equity

        As of March 31, 1998, the Company had four classes of convertible
        preferred stock, Class A-1, A-2, A-3, and A-4. The holders of Class A-1,
        A-2 and A-4 convertible preferred stock are entitled to one vote for
        each share of common stock issuable upon conversion of the preferred
        stock at the time the vote is taken. Class A-3 stock has no voting
        privileges, except where mandated by law. All classes of preferred stock
        share ratably with the common stockholders in dividends and upon
        liquidation. Shares of convertible preferred stock are convertible to
        common stock on a one-to-one basis. Preferred stock may be converted to
        common stock at any time, and the Board of Directors may require
        conversion of all outstanding preferred shares upon the closing of a
        Qualified Public Offering. All classes of preferred stock contain
        anti-dilution privileges whereby the conversion price will be reduced if
        any shares of common stock are sold for a lower price than the stated
        conversion price.

        Prior to March 28, 1997, the Company had 3,600 shares of common stock
        authorized, issued and outstanding which were owned equally by the
        former shareholders. As of March 28, 1997 these common stock shares were
        cancelled and new common stock shares were issued. The new common stock
        shares have a par value of $0.017 per share.

13.     Stock Option Plan

        The Company has elected to follow APB 25 "Accounting for Stock Issued to
        Employees" and related interpretations in accounting for its employee
        stock options because, as discussed below, the alternative fair value
        accounting provided for under SFAS 123 "Accounting for Stock-Based
        Compensation" requires use of option valuation models that were not
        developed for use in valuing employee stock options.


                                      F-48
   163

        The 1997 Long Term Incentive Stock Plan, as amended (the Plan), allows
        grants of options to purchase up to 200,000 shares of Series A-2
        Preferred Stock and 16,667 shares of Series A-4 Preferred Stock. The
        preferred stock is convertible into common stock at any time. Stock
        options granted under the Plan are exercisable over a period of ten
        years and vest over a period of three to five years. As of March 31,
        1998, 178,749 stock options have been granted to various employees and
        approximately 37,918 remained available for grant under the Plan. In
        addition, an officer of the Company received options to purchase 34,933
        shares of Series A-2 Preferred Stock and 2,538 shares of Series A-4
        Preferred Stock. These options are in addition to those reserved under
        the Plan and contain anti-dilution privileges. No options have been
        exercised. There were no stock options granted, issued or exercised
        during the years ended January 31, 1996 and 1997, or the period from
        February 1, 1997 to March 27, 1997.

        The fair value for these options was estimated at the date of grant
        using a Black-Scholes option pricing model with the following weighted
        average assumptions: (i) no dividend yield, (ii) volatility of
        effectively zero, (iii) risk-free interest rate of seven percent and
        (iv) expected life of ten years.

        The following table summarizes the information regarding stock options
        as of March 31, 1998:

        Had compensation expense for the Company's 1998 stock-based compensation
        been recorded under fair market value principles applicable under SFAS
        123, the Company would have recorded $62,000 of additional compensation
        expense, and net income would have been reduced to $2,034,000 for the
        year ended March 31, 1998. Basic earnings per share and fully diluted
        earnings would have been reduced to $0.54 and $0.51, respectively, for
        the year ended March 31, 1998 had the Company recorded the additional
        compensation expense.

14.     Concentration of Credit Risk

        The Company had several customers which individually account for greater
        than ten percent of net sales during the periods presented as follows:

15.     Disclosure About the Fair Value of Financial Instruments

        The following methods and assumptions were used to estimate the fair
        value of each class of financial instrument for which it is practicable
        to estimate:

        Cash-The carrying amount is a reasonable estimate of fair value. Thus,
        the fair value is disclosed on the consolidated balance sheets.

        Note Receivable-The notes receivable bear interest at a variable rate;
        therefore fair value is assumed to approximate carrying value. Thus, the
        fair value is disclosed on the consolidated balance sheets.

        Long-Term Debt-The notes payable bear interest at a variable rate;
        therefore fair value is assumed to approximate carrying value. Thus, the
        fair value is disclosed on the consolidated balance sheets.

16.     Subsequent Events

        a.      Rosewood Acquisition

                In April 1998, the Company consummated the acquisition of all
                outstanding Rosewood shares. The purchase price consisted of
                cash payments totaling $21,773,000, a 9% subordinated note in
                the amount of $1.5 million, and a variable number of shares of
                the Company's Series A-6 preferred stock with a fixed value of
                $1.0 million. The purchase price also includes $195,000 of
                transactional costs. The number of shares issued is subject to
                adjustment based on additional analysis of the value of the
                Company. The agreement also provides that, in the event an
                initial public offering, as defined, is not consummated within
                five years of the purchase, the seller may elect to have the
                shares repurchased by the Company at a price equal to the then
                fair market value. Alternately, the Company may elect to acquire
                the seller's shares at the fair market value.

        b.      Proposed acquisition (unaudited)

                In June 1998, the Company signed a letter of intent to acquire a
                modular building manufacturer located in the southeastern United
                States. The proposed purchase price consists of a base price of
                $2.0 million plus additional consideration based on future
                earnings.

        c.      Proposed merger (unaudited)

                The Company has entered into a Plan of Reorganization and Merger
                dated September 28, 1998 with Modtech, Inc. Under terms of the
                agreement, all equity instruments will be converted into equity
                instruments of Modtech Holdings, Inc. or redeemed for cash.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1998

1.      Financial Statements

        The accompanying consolidated financial statements included herein have
        been prepared by the Company, without audit, and include all adjustments
        which are, in the opinion of Management, necessary for a fair
        presentation of the financial position as of June 30, 1998, the results
        of operations and cash flows for the three-month period ended June 30,
        1997 and June 30, 1998 pursuant to the rules and regulations of the
        Securities and Exchange Commission (SEC). All such adjustments are of a
        normal recurring nature. Certain information and footnote disclosures
        normally included in consolidated financial statements prepared in
        accordance with generally accepted accounting principles have been
        condensed or omitted pursuant to such rules and regulations. Although
        the Company believes that the disclosures in such financial statements
        are adequate to make the information presented not misleading, these
        consolidated statements should be read in conjunction with the Company's
        fiscal 1998 audited consolidated financial statements and notes thereto
        included in this Form S-4. The results of operations for the three-month
        periods are not necessarily indicative of the results for a full year.
        The financial statements include the accounts, from the date of
        acquisition, of Office Master (acquired in February 1998) and Rosewood
        (acquired in April 1998--see Note 6.)

3.      Comprehensive Income

        In June 1997, the Financial Accounting Standards Board (FASB) issued
        Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
        Comprehensive Income". This Statement requires that all items that meet
        the definition of comprehensive income be reported in a financial
        statement for the period in which they are recognized. This Statement is
        effective for fiscal years beginning after December 15, 1997 and was
        adopted by the Company in the quarter ended June 30, 1998.

        The Company had no comprehensive income adjustments for the period ended
        June 30, 1998.

4.      Earnings per Share

        The Company accounts for earnings per share in accordance with SFAS No.
        128, "Earnings per Share." This Statement requires the presentation of
        both basic and diluted net income per share for financial statement
        purposes. Basic net income per share is computed by dividing income
        available to common shareholders by the weighted average number of
        common shares outstanding. Diluted net income per share includes the
        effect of the potential shares outstanding, including dilutive stock
        options using the treasury stock method.

        Concurrent with the proposed merger, all outstanding shares of preferred
        stock will convert into common stock. Pro forma earnings per share is
        calculated using the pro forma weighted average number of common shares
        outstanding that would have resulted from the preferred stock conversion
        to common shares.

        The following table reconciles the components of the pro forma basic net
        income per share calculation to pro forma diluted net income per share.

5.      Income Taxes

        The effective tax rate differs from that computed at the Federal
        statutory rate of 34 percent principally because of the effect of state
        income taxes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareholder of
Office Master of Texas, Inc.:

We have audited the accompanying balance sheet of Office Master of Texas, Inc.
(a Texas corporation) as of December 31, 1997, and the related statements of
income and retained earnings and cash flows for the year then ended. 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 audit.

We conducted our audit 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 audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Office Master of Texas, Inc. as
of December 31, 1997, and the results of its operations and its cash flows for
the year then ended in conformity with generally accepted accounting principles.

As discussed more fully in Note 9 to the financial statements, the Company's
shareholder has entered into a letter of intent to sell all shares of common
stock currently outstanding.

1.      COMPANY OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:

Organization and Business

Office Master of Texas, Inc. (the "Company"), manufactures modular buildings at
its production facility in Glen Rose, Texas, and distributes to customers
throughout the United States, primarily in the South. The Company's customers
include dealers and leasing companies who then sell or lease the buildings to
third parties operating in various industries. The Company is 100% owned by
Bertrand Taylor (the "shareholder").

Inventories

   
Inventories consist of raw materials, work-in-process, and finished goods and
are stated at the lower of cost or market on first-in first-out basis. The
following is a summary of inventory by component:
    
   

                                
       Raw materials          $458,228
       Work-in-process          95,669
       Finished goods          285,627

    

Work-in-process consists of raw materials and overhead.

Equipment and Leasehold Improvements

Equipment and leasehold improvements are stated at cost. Depreciation is
computed using the straight-line method over the following useful lives:

       Buildings                            31.5 years
       Vehicles and equipment               Five to ten years
       Leasehold improvements               Useful life or life of
                                            the lease, whichever is
                                            shorter

Major renewals or betterments are capitalized while maintenance costs and
repairs are expensed in the period incurred.

Revenue Recognition

The Company recognizes revenue upon completion of the buildings and transfer of
title. Buildings are maintained on the Company's property until the customer
arranges for delivery.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

2.      NOTE RECEIVABLE FROM SHAREHOLDER:

Note receivable from the shareholder represents advances to the shareholder.
Interest accrues monthly on the receivable at 6.5%. Pursuant to the agreement
entered into as described in Note 9, this receivable will be paid prior to the
close of the transaction described therein.

3.      NOTES PAYABLE:

Notes payable consists of five secured notes payable to two banks. These notes
accrue interest at rates ranging from 9.5% to 10.5%. Amounts due on the note
payable in future years are as follows:

entered into as described in Note 9, this payable will be paid prior to the

shareholder and currently pays a monthly rental fee of $3,300 pursuant to an
informal agreement. The Company also incurred rental expense during a portion of
the year related to a parcel of land adjacent to the Company's facility. Such
land was sold to the Company during the year in exchange for an agreement to
employ additional county residents. The current year rent expense was $60,906.

7.   ACCRUED LIABILITIES:

The components of accrued liabilities at December 31, 1997, consist of the
following:

during the year, and approximately 93% of accounts receivable at December 31,
1997.

9.      SUBSEQUENT EVENT:

On December 10, 1997, the shareholder entered into an agreement to sell all of
the outstanding shares of the Company for an amount substantially in excess of
the net book value of the Company. Pursuant to this agreement, the shareholders
agree to, among other things, (1) repay all related party notes and advances,
plus accrued interest, (2) enter into one-year consulting agreements, and (3)
enter into five-year noncompete agreements. The transaction is expected to close
in February 1998.

Major renewals or betterments are capitalized while maintenance costs and
repairs are expensed in the period incurred. Upon retirement or disposal of
depreciable assets, the cost and related accumulated depreciation are removed
from the accounts and the resulting gain or loss is reflected in operations.
Statement of Financial Accounting Standards (SFAS) No. 121, Accounting for the
Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of,
requires that long-lived assets to be held and used be


                                      F-71

reviewed for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable based on the
estimated future cash flows. In management's opinion, no such events or changes
in circumstances have occurred.

         PRODUCT WARRANTY

The Company provides a one-year parts and labor warranty on units sold. The
Company provides, by a current charge to income, an amount it estimates will be
needed to cover future warranty obligations for products sold during the year.
The accrued liability for warranty costs of $71,600 and $31,000 at December 31,
1997 and 1996, respectively, is included in accrued liabilities in the
accompanying balance sheets.

         REVENUE RECOGNITION

The Company recognizes revenue upon completion of the buildings and transfer of
title to the customer. Customer-owned buildings are often maintained on the
Company's premises until the customer arranges for pickup and delivery.

         USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

         OTHER INCOME

Other income for the year ended December 31, 1997 included approximately
$130,000 of bad debt recovery and a dividend of approximately $50,000 received
from the Company's workers' compensation carrier.

(4)     INCOME TAXES:

The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes. Deferred tax assets and liabilities are recorded
based on the differences between the financial statement and tax bases of assets
and liabilities at the tax rates in effect when these differences are expected
to reverse. The deferred provision for income taxes results from timing
differences in the recognition of certain revenue and expense items for
financial reporting and income tax reporting purposes.

The provision for income taxes for the years ended December 31 is comprised of
the following:

make a profit sharing contribution. To be eligible for a profit sharing
contribution, the employee must work at least 1,000 hours during the Plan year
and be employed by the Company on the last day of the Plan year. The Company's

outstanding shares of the Company for an amount in excess of the net book value
of the Company. Pursuant to this agreement, the shareholders agree to, among
other things, enter into noncompete, consulting and employment agreements. The
transaction is expected to close in April 1998.

      Section 145 of the Delaware General Corporation Law empowers the
Registrant to indemnify, subject to the standards therein prescribed, any person
in connection with any action, suit or proceeding brought or threatened by
reason of the fact that such person is or was a director, officer, employee or
agent of the Registrant or is or was serving as such with respect to another
corporation or other entity at the request of the Registrant. Article VI of the
Registrant's By-Laws provides that such Registrant shall, to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law, indemnify its
directors and officers from and against any and all of the expenses, liabilities
or other matters referred to in or covered by said Article.

      As permitted by Section 102 of the Delaware General Corporation Law, the
Registrant's Certificates of Incorporation includes a provision eliminating, to
the extent permitted by Delaware law, the personal liability of each director of
the Registrant to the Registrant or any of its stockholders for monetary damages
resulting from breaches of such director's fiduciary duty of care.

ITEM 22.  UNDERTAKINGS.

      The undersigned Registrant hereby undertakes:

      (a) to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

           (i)  to include any prospectus required by section 10(a)(3) of the 
Securities Act of 1933 (the "Securities Act");

           (ii) to reflect in the prospectus any facts or events arising after
the effective date of this Registration Statement (or the most recent
post-effective amendment hereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in this Registration
Statement.

      (b) that, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment 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.

      (c) to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

      (d) to respond to requests for information that is incorporated by
reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form,
within one business day of receipt of such request, and to send the incorporated
documents by first-class mail or equally prompt means. This includes information
contained in documents filed subsequent to the effective date of the
registration statement through the date of responding to the request.

      (e) to supply by means of a post-effective amendment all information
concerning a transaction, and SPI being acquired involved therein, that was not
the subject of and included in the registration statement when it became
effective.

      (f) that, for purposes of determining any liability under the Securities
Act of 1933, each filing of a Registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of any employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement 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.

      (g) insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrants pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
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

                                      II-3

   193

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.

undersigned, thereunto duly authorized in Newport Beach, California on October
