PROSPECTUS
                            FOCUS ENHANCEMENTS, INC.

                        1,441,224 Shares of Common Stock

     This  Prospectus  relates  to the offer and sale from time to time of up to
1,441,224  shares (the "Shares") of common stock,  $.01 par value per share (the
Common  Stock") of FOCUS  Enhancements,  Inc.  (the  "Company"),  by the Selling
Stockholders named herein (the "Selling  Stockholders"),  or by their respective
pledgees, donnees, transferees or other successors in interest that receive such
Shares as a gift,  partnership  distribution or other non-sale related transfer.
Of the 1,441,224  Shares being offered hereby:  (i) 1,092,150 Shares were issued
to JNC Opportunity Fund Ltd. (the "Investor");  (ii) 327,645 Shares are issuable
upon the exercise of warrants (the "Investor  Warrants") issued to the Investor;
and (iii) 21,429 Shares are issuable upon the exercise of warrants issued to the
placement agent and its designee (the "Broker  Warrants" and,  together with the
Investor Warrants,  the "Warrants").  The Shares and Warrants were issued by the
Company to the Selling Stockholders on March 3, 1998 in a private placement (the
"March 98 Offering"). To the extent that the Warrants are exercised, the Company
will receive  proceeds equal to the exercise price of the Warrants.  The Company
will  not  receive  any  proceeds  from the sale of the  Shares  by the  Selling
Stockholders.  The expenses of  registration  of the Shares which may be offered
hereby under the Securities Act of 1933, as amended (the "Securities  Act") will
be paid by the Company.

         The  Shares  covered  under the  Registration  Statement  of which this
Prospectus  is a part may be  offered  for sale  from time to time by or for the
account of the Selling Stockholders,  or their pledgees,  donees, transferees or
other successors in interest, in the open market, on the NASDAQ Small Cap Market
or on one or more  exchanges on which the Shares are then  listed,  in privately
negotiated  transactions,  in an underwritten offering, in a combination of such
methods, or by any other legally available means, at market prices prevailing at
the time of such sale, at prices related to such  prevailing  market prices,  at
negotiated prices or at fixed prices. The Shares are intended to be sold through
one or more  broker-dealers or directly to purchasers.  Such  broker-dealers may
receive  compensation in the form of discounts,  concessions or commissions from
the Selling Stockholders,  their successors in interest and/or the purchasers of
the  Shares  for whom such  broker-dealers  may act as agent or to whom they may
sell as principal, or both (which compensation as to a particular  broker-dealer
may be in excess of  customary  commissions).  The Selling  Stockholders,  their
successors in interest and/or any  broker-dealers  acting in connection with the
sale of the Shares  hereunder may be deemed to be underwriters  with the meaning
of  Section  2(11)  of  the  Securities   Act,  and  any  commissions  or  other
compensation  received by them and any profits realized by them on the resale of
the  Shares as  principals  may be deemed  underwriting  compensation  under the
Securities Act. See "SELLING STOCKHOLDERS" and "PLAN OF DISTRIBUTION."

         The Common  Stock is traded on the  Nasdaq  SmallCap  Market  under the
symbol FCSE.  On March 31,  1998,  the last sale price of the  Company's  Common
Stock as reported on the Nasdaq SmallCap Market was $3 1/8.

                                       Selling  Stockholders  at  the  time  of
                                       sale. 

USE OF PROCEEDS...................     To the  extent  that  the  Warrants  are
                                       exercised,  the  Company  intends to use
                                       the net  proceeds  for  general  working
                                       capital   purposes.   The  Company  will
                                       receive no part of the proceeds from the
                                       sale of the Shares  registered  pursuant
                                       to this Registration Statement.

                                  RISK FACTORS

         An investment in the securities  offered hereby  involves a high degree
of risk and should only be purchased  by investors  who can afford to lose their
entire  investment.  The  following  factors,  in  addition  to those  discussed
elsewhere in the  Prospectus,  should be considered  carefully in evaluating the
Company and its business.

         Future  Capital  Needs.  At December 31, 1997,  the Company had working
capital of $2,619,300, cash and cash equivalents of $719,851 and was fully drawn
on its line of credit  (approximately  $720,000 at December  31,  1997) with its
bank and its $1.5 million term note with an unaffiliated  lender.  Historically,
the  Company  has been  required  to meet its  short- and  long-term  cash needs
through  debt and the sale of Common  Stock in private  placements  in that cash
flow from operations has been  insufficient.  During 1997, the Company  received
approximately  $6,082,000 in net proceeds  from the exercise of warrants,  stock
options  and the sale of Common  Stock.  In March  1998,  the  Company  received
approximately  $2,800,000  in net proceeds  from the sale of Common Stock in the
March 98 Offering.

         The Company's future capital  requirements will depend on many factors,
including  cash flow from  operations,  continued  progress in its  research and
development programs,  competing technological and market developments,  and the
Company's ability to market its products successfully.  During 1998, the Company
may be required to raise additional  funds through equity or debt financing,  of
which there can be no assurance.  Any equity  financing could result in dilution
to the  Company's  then-existing  stockholders.  Sources of debt  financing  may
result in higher interest expense. Any financing, if available,  may be on terms
unfavorable to the Company. If adequate funds are not available, the Company may
be required to curtail its activities significantly.

         Reliance on Major  Customers.  For the year ended  December  31,  1997,
approximately  16% of the Company's  revenues were derived from sales to a major
distributor, approximately 27% of the Company's revenues were derived from sales
to a major manufacturer of personal computers and its contract manufacturer, and
approximately  11% of the Company's  revenues were derived from sales to a major
television  manufacturer.  Management expects that sales to these customers will
continue to represent a significant percentage of the Company's future revenues.
The Company does not have long-term  contracts pursuant to which any customer is
required to purchase any minimum  amount of products.  There can be no assurance
that the Company will continue to receive orders of the same magnitude as in the
past from  existing  customers  or that it will be able to market its current or
proposed  products  to new  customers.  The loss of any  major  customer  by the
Company would have a materially adverse effect on the business of the Company as
a whole.

         History of  Operating  Losses.  The  Company  has  experienced  limited
profitability  since its inception and at December 31, 1997,  had an accumulated
deficit of  $22,411,611.  The Company  incurred  net losses of  $10,772,410  and
$1,986,079 for the years ended December 31, 1996 and 1997, respectively.
There can be no assurance that the Company will be profitable in 1998.

         Limited Availability of Capital under Credit Arrangements with Lenders.
The Company  maintains a line of credit with Silicon  Valley Bank which is fully
drawn  ($720,000  was owed to the bank at December  31,  1997).  At December 31,
1997,  the Company was in violation of certain  debt  covenants  relating to the
line of credit. In addition, the line of credit was scheduled to expire on March
8, 1998.  The Company has  received a waiver of the  covenants  from the bank, a
revision of the loan covenants and an agreement to extend the line until June 8,
1998. The Company is currently in  discussions  with another lender to refinance
this line.

                                       -5-

         The Company also owes $1.5 million to an  unaffiliated  lender pursuant
to a term note that currently accrues interest at a revolving rate of prime plus
4%, is payable  quarterly in arrears at the end of December,  March,  June,  and
September,  and was  due  February  1,  1996.  On June  28,  1996,  the  Company
negotiated  an amendment to the term note with the lender to extend the due date
of the term note to March 31,  1997.  Pursuant  to the  amendment,  the  Company
granted the lender a second security  interest in all the assets of the Company.
The Company is currently negotiating an additional extension with the lender.

         In the event that the Company is  unsuccessful  in refinancing its bank
line of credit or that the  unaffiliated  lender does not extend the due date of
its term note,  the Company  would be required to repay the amounts  outstanding
from working capital or from equity or debt financing.

         Market  Acceptance.  The  Company's  sales and  marketing  strategy  is
targeted to sales of its PC-to- TV video-graphics  products to the Windows,  Mac
OS markets,  including computer  manufacturers,  VGA graphic card developers and
VGA  chip  developers,  as well as to  television  manufacturers.  Although  the
Company has to date experienced success in penetrating these markets,  there can
be no  assurance  that the  Company's  marketing  strategy  will  continue to be
effective  and  that  current  customers  will  continue  to buy  the  Company's
products.  Market acceptance of the Company's current and proposed products will
depend upon the  ability of the Company to  demonstrate  the  advantages  of its
products over other PC-to-TV video- graphics products.

         Reliance on Vendors. In the year ended December 31, 1997, approximately
90% of the components for the Company's  products were secured and  manufactured
on a turnkey basis by two vendors. In the event that either vendor were to cease
supplying the Company, management believes there are alternative vendors for the
components for the Company's  products.  However,  the Company would  experience
short-term delays in the shipment of its products.

         Dependence on Timely Delivery of the FOCUS Scan 300 Chip. In late 1997,
the  Company  completed  development  of an ASIC  called the FOCUS Scan 300 Chip
which the Company  will  incorporate  into all of its next  generation  PC-to-TV
video-graphics  products.  The  Company  is  relying  on an  outside  vendor  to
manufacture  its  requirements  for  the  Chip.  A  significant  portion  of the
Company's  anticipated  revenues  and gross  margins for 1998 are  dependent  on
timely delivery of sufficient  quantities of the FOCUS Scan 300 Chip in order to
fill  pending and  anticipated  orders.  In the event that the Company  does not
receive sufficient quantities of the Chip to fill orders, the Company's revenues
and profitability for 1998 could be adversely effected.

         Technological  Obsolescence.   The  Windows  and  Mac  OS  markets  are
characterized  by extensive  research and  development  and rapid  technological
change resulting in product life cycles of nine to eighteen months.  Development
by others of new or improved  products,  processes or technologies  may make the
Company's  products  or proposed  products  obsolete  or less  competitive.  The
Company will be required to devote substantial  efforts and financial  resources
to enhance its existing  products and to develop new  products.  There can be no
assurance that the Company will succeed with these efforts.

         Competition.  The Windows and Mac OS markets are extremely competitive.
The Company  currently  competes with other  developers  of PC-to-TV  conversion
products  and with  video-graphic  integrated  circuit  developers.  Many of the
Company's  competitors  have greater market  recognition and greater  financial,
technical,  marketing and human resources than the Company. Although the Company
is not currently aware of any announcements by its competitors that would have a
material impact on the Company or its operations, there can be no assurance that
the Company will be able to compete  successfully  against existing companies or
new entrants to the marketplace.

                                       -6-

         Component Supply Problems.  The Company purchases all of its parts from
outside  suppliers and from time to time  experiences  delays in obtaining  some
components or  peripheral  devices.  The Company  attempts to reduce the risk of
supply interruption by evaluating and obtaining  alternative sources for various
components or peripheral devices. However, there can be no assurance that supply
shortages  will not occur in the future which could  significantly  increase the
cost,  or delay  shipment  of,  the  Company's  products,  which  in turn  could
adversely affect its results of operations.

         Protection of Proprietary  Information.  Although the Company currently
has three patents  pending,  all with respect to its PC-to-TV  video  conversion
chips, and anticipates  filing another patent  application in the second quarter
of this year,  the Company  does not  currently  have any  patents.  The Company
treats its technical data as confidential  and relies on internal  nondisclosure
safeguards,  including  confidentiality  agreements with employees,  and on laws
protecting trade secrets to protect its proprietary information. There can be no
assurance that these measures will adequately protect the confidentiality of the
Company's proprietary  information or that others will not independently develop
products or technology  that are equivalent or superior to those of the Company.
While it may be necessary or desirable in the future to obtain licenses relating
to one or more of its  products or  relating to current or future  technologies,
there can be no assurance that the Company will be able to do so on commercially
reasonable terms.

                                   THE COMPANY

         FOCUS   Enhancements,   Inc.  (the  "Company"  or  "FOCUS")  internally
develops,  markets and sells  worldwide  a line of  proprietary  PC-to-TV  video
conversion products for PC's and Macintoshes (R). Based on an independent survey
by Frost & Sullivan,  the Company is an industry  leader in the  development and
marketing of PC-to-TV  video  conversion  products that make personal  computers
"TV-ready" and televisions "PC- ready."

         The Company's  proprietary  PC-to-TV video conversion  products include
video output devices marketed and sold under the Company's  registered trademark
"TView."  All of the  Company's  PC-to-TV  conversion  products  enable users to
transmit at  low-cost,  high-quality,  computer  generated  images from any DOS,
Windows or Mac OS based  personal  computer to any television of any size with a
standard RCA or S-Video interface.  FOCUS' PC-to-TV  technology  provides sharp,
flicker-free,  computer-generated  images on televisions for multimedia/business
presentations,  classroom/training sessions, game playing, collective viewing of
computer applications, and Internet browsing.

         The  Company  markets  and sells its FOCUS  branded  consumer  products
globally  through a network  of  distributors,  volume  resellers,  mail  order,
value-added resellers ("VARs") and original equipment manufacturers ("OEMs"). In
North  America,  the Company  markets and sells its  products  through  national
distributors  such as Ingram Micro D, D & H, Academic and Nuvo;  national volume
resellers  such as CompUSA,  Computer  City,  Micro Center,  Staples and through
third party mail order companies such as MicroWarehouse,  Multiple Zones, Global
Direct, PC Connection and CDW.

         In addition,  the FOCUS branded PC-to-TV products have been selected by
leading  personal  computer  manufacturers  to be marketed with the use of their
select  brand of personal  computers.  Compaq,  and Toshiba  have  included  the
Company's  PC-to-TV  products on their selected market price lists,  and promote
the FOCUS PC-to-TV products in their box materials.

         The Company also markets and sells its products internationally in over
30 countries by  independent  distributors  in each country.  These  independent
distributors market and sell the FOCUS branded products to retailers, mail order
companies, and VARs in their respective countries.

         In addition to the FOCUS branded products,  the Company markets,  sells
or licenses its proprietary PC-to-TV technology to television manufacturers such
as Philips Consumer Electronics and Zenith Electronics, and to personal computer
manufacturers  such as Apple  Computer.  The Company is currently in discussions
with  several  other  PC  manufacturers,   television  manufacturers,  VGA  chip
developers and VGA card developers globally.

         The  Company  was  founded  in  December   1991,  as  a   Massachusetts
corporation and was  reincorporated in Delaware in April 1993. In December 1993,
the  Company  acquired  Lapis  Technologies  Inc.  ("Lapis"),   a  developer  of
high-quality,  low-cost  Macintosh PC to TV video graphics  products.  Effective
September 30, 1996, the Company  consummated the  acquisition of TView,  Inc., a
developer of PC-to-TV video  conversion ASIC  technology.  This  acquisition has
played a major  strategic role in allowing  FOCUS to gain a major  technological
lead over  competitors in the video scan conversion  category and has positioned
FOCUS as a leader in PC-to-TV  video  conversion  technology.  On September  30,
1997, the Company sold its line of computer connectivity products.

         The  Company's  principal  executive  offices  are located at 142 North
Road,  Sudbury,  Massachusetts  01776.  Its research and  development  center is

                                 USE OF PROCEEDS

         The  Company  will not  receive  any  proceeds  from the  resale by the
Selling Stockholders of the Shares.

         Management  intends  to use  any  proceeds  from  the  exercise  of the
Warrants  for  general  working  capital  purposes  including   expenditures  in
connection with the development,  sales and marketing of future products for the
Company.

                              SELLING STOCKHOLDERS

         The Shares being  offered for resale by the Selling  Stockholders  were
acquired in connection  with the March 98 Offering and include  shares of Common
Stock  issuable upon exercise of the Warrants.  In connection  with the March 98
Offering,  the Company  granted the Selling  Stockholders  certain  registration
rights pursuant to which the Company agreed to keep the Registration  Statement,
of which this  Prospectus is a part,  effective  until the date that all of such
Shares have been sold pursuant to the  Registration  Statement or the Shares are
otherwise  eligible for resale  pursuant to Rule 144(k) of the  Securities  Act,
whichever  occurs  first.  The  Company  has  agreed to  indemnify  the  Selling
Stockholders  and  each  of  their  officers,   directors,  members,  employees,
partners,  agents and each person who controls  any of the Selling  Stockholders
against certain expenses,  claims,  losses,  damages and liabilities (or action,
proceeding  or inquiry  by any  regulator  or  self-regulatory  organization  in
respect thereof).  The Company has agreed to pay its expenses of registering the
Shares under the Securities Act,  including  registration  and filing fees, blue
sky expenses,  printing expenses,  accounting fees,  administrative expenses and
its own counsel fees.

         The  following  table sets forth the name of each Selling  Stockholder,
the  number  of  shares  of  Common  Stock  beneficially  owned by such  Selling
Stockholder  as of March 3, 1998 and the number of Shares being  offered by each
Selling  Stockholder.  The Shares being offered  hereby are being  registered to
permit public secondary trading,  and the Selling  Stockholders may offer all or
part  of the  Shares  for  resale  from  time to  time.  However,  such  Selling
Stockholders  are under no obligations to sell all or any portion of such Shares
nor are such Selling Stockholders obligated to sell any Shares immediately under
this  Prospectus.  All  information  with  respect to share  ownership  has been
furnished by the Selling Stockholders. Because the Selling Stockholders may sell
all or part of their  Shares,  no  estimates  can be given as to the  number  of
Shares  that will be held by any Selling  Stockholder  upon  termination  of any
offering made hereby. See "PLAN OF DISTRIBUTION."

(1)      Except as set forth in footnote (5) below, beneficial ownership is determined in accordance with Rule
         13d-3 of the Exchange Act. The persons named in the table above have sole voting and investment power
         with respect to all shares of Common Stock shown as beneficially owned by them.

(2)      Assumes all Shares offered hereby are sold in the Offering.

(3)      Includes 327,645 Shares issuable upon exercise of the Investor  Warrants.  The Investor  Warrants are
         exercisable  until March 3, 2005 if at any time prior to August 25, 1999,  the average of the closing
         bid prices of the Company's  Common Stock during any  consecutive 20 trading days is equal to or less
         than $2.7469.

(4)      Represent Shares issuable upon exercise of the Broker  Warrants.  The Broker Warrants are exercisable
         at a price of $4.2118 per share until March 3, 2003.

(5)      Pursuant to the terms of the Warrants,  the Warrants are exercisable by any holder only to the extent
         that the number of shares of Common Stock  thereby  issuable,  together  with the number of shares of
         Common  Stock owned by such  holder and its  affiliates  (but not  including  shares of Common  Stock
         underlying  unexercised  portions of the  Warrants)  would not exceed  9.99% of the then  outstanding
         Common Stock as  determined in accordance  with Section 13(d) of the Exchange Act.  Accordingly,  the
         number of Shares  set forth in the table for a Selling  Stockholder  may  exceed the number of Shares
         that such  Selling  Stockholder  could  own  beneficially  at any given  time  through  such  Selling
         Stockholder's  ownership  of the  Warrants.  In that  regard,  beneficial  ownership  of such Selling
         Stockholder set forth in the table is not determined in accordance with Rule 13d-3 under the Exchange
         Act.
</FN>


                              PLAN OF DISTRIBUTION

         The Shares may be sold or distributed  from time to time by the Selling
Stockholders or by pledgees, donees or transferees of, or successors in interest
to, the  Selling  Stockholders,  directly to one or more  purchasers  (including
pledgees)  or through  brokers,  dealers or  underwriters  who may act solely as
agents or may acquire Shares as principals,  at market prices  prevailing at the
time of sale, at prices related to such prevailing  market prices, at negotiated
prices or at fixed prices,  which may be changed. The distribution of the Shares
may be effected in one or more of the following  methods:  (i) ordinary  brokers
transactions, which may include long or short sales, (ii) transactions involving
cross  or block  trades  or  otherwise  on the  NASDAQ  SmallCap  Market,  (iii)
purchases by brokers,  dealers or  underwriters  as principal and resale by such
purchasers  for their own  accounts  pursuant to this  Prospectus,  (iv) "at the
market" to or through  market  makers or into an existing  market for the Common
Stock,  (v) in other ways not  involving  market makers or  established  trading
markets,  including direct sales to purchasers or sales effected through agents,
(vi)  through  transactions  in  options,  swaps or other  derivatives  (whether
exchange listed or otherwise),  or (vii) any combination of the foregoing, or by
any other legally  available  means.  In addition,  the Selling  Stockholders or
their  successors  in  interest  may  enter  into  hedging   transactions   with
broker-dealers  who may engage in short  sales of shares of Common  Stock in the
course of hedging the positions they assume with the Selling  Stockholders.  The
Selling  Stockholders or their successors in interest may also enter into option
or other  transactions  with  broker-dealers  that  require the delivery by such
broker-dealers of the Shares,  which Shares may be resold thereafter pursuant to
this Prospectus.

         Brokers,   dealers,   underwriters  or  agents   participating  in  the
distribution  of the Shares may receive  compensation  in the form of discounts,
concessions or commissions from the Selling  Stockholders  and/or the purchasers
of Shares for whom such broker-dealers may act as agent or to whom they may sell
as principal,  or both (which compensation as to a particular  broker-dealer may
be in excess of customary commissions).

                                      -10-

The Selling  Stockholders and any  broker-dealers  acting in connection with the
sale of the Shares hereunder may be deemed to be underwriters within the meaning
of Section 2(11) of the Securities Act, and any commissions received by them and
any profit  realized by them on the resale of Shares as principals may be deemed
underwiting  compensation  under the Securities Act. Neither the Company nor any
Selling Stockholder can presently estimate the amount of such compensation.  The
Company knows of no existing  arrangements  between any Selling  Stockholder and
any other stockholder, broker, dealer, underwriter or agent relating to the sale
of distribution of the Shares.

         Each  Selling  Stockholder  and any other  persons  participating  in a
distribution  of  securities  will be subject to  applicable  provisions  of the
Exchange  Act and the  rules  and  regulations  thereunder,  including,  without
limitation,  Regulation M, which may restrict  certain  activities of, and limit
the timing of purchases and sales of securities  by,  Selling  Stockholders  and
other persons participating in a distribution of securities.  Furthermore, under
Regulation M, persons  engaged in a  distribution  of securities  are prohibited
from simultaneously  engaging in market making and certain other activities with
respect  to  such  securities  for a  specified  period  of  time  prior  to the
commencement  of  such   distributions   subject  to  specified   exceptions  or
exemptions.  All of the foregoing may affect the marketability of the securities
offered hereby.

         Any  securities  covered  by this  Prospectus  that  qualify  for  sale
pursuant to Rule 144 under the Securities Act may be sold under that Rule rather
than pursuant to this Prospectus.

         There can be no assurance that the Selling  Stockholders  will sell any
or all of the shares of Common Stock offered by them hereunder.

                                  LEGAL MATTERS

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

         Insofar as indemnification for liabilities arising under the Act may be
permitted to  directors,  officers  and  controlling  persons of the  Registrant
pursuant to the foregoing  provisions,  or otherwise,  the  Registrant  has been
advised that in the opinion of the Commission  such  indemnification  is against
public policy as expressed in such Act and is, therefore,  unenforceable. In the
event that a claim for indemnification  against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the Shares 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 such Act and will
be governed by the final adjudication of such issue.

Item 15. Indemnification of Directors and Officers

         Section 145 of the Delaware General Corporation Law empowers a Delaware
corporation  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  corporation  or was  serving  as such with  respect  to another
corporation or other entity at the request of such corporation.

         The Delaware General Corporation Law, the Company's charter and by-laws
provide  for   indemnification  of  the  Company's  directors  and  officer  for
liabilities  and expenses  that they may incur in such  capacities.  In general,
directors  and officers are  indemnified  with respect to actions  taken in good
faith in a manner  reasonably  believed  to be in, or not  opposed  to, the best
interests of the Company, and with respect to any criminal action or proceeding,
actions that the  indemnitee  had no reasonable  cause to believe were unlawful.
Reference is made to the Company's Second Restated Certificate of Incorporation,
as amended and Restated By-laws incorporated herein by reference.

         The  Underwriting  Agreement  executed in connection with the Company's
initial public  offering  provides that the  underwriters  are obligated,  under
certain circumstances,  to indemnify directors, officers and controlling persons
of the Company  against certain  liabilities,  including  liabilities  under the
Securities Act of 1933, as amended (the "Act"). Reference is made to the form of
Underwriting  Agreement  previously  filed  as  Exhibit  1.1  to  the  Company's
Registration Statement on Form SB-2, No. 33-60248-B.

         The Company has obtained directors and officers liability insurance for
the benefit of its directors and certain of its officers.

         Reference  is  made  to the  Underwriting  Agreement  described  above,
pursuant to which the Registrant  agreed to indemnify each  underwriter and each
person,  if any, who controls any underwriter  within the meaning of the Act, or
the Securities Exchange Act of 1934, as amended,  against certain types of civil
liabilities arising in connection with the aforementioned Registration Statement
or the prospectus contained therein.

Item 17. Undertakings

(a)      The undersigned Registrant hereby undertakes:

         (1)      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;

         (ii)     To reflect in the prospectus any facts or events arising after
                  the effective date of the registration  statement (or the most
                  recent post-effective  amendment thereof) which,  individually
                  or in the  aggregate,  represent a  fundamental  change in the
                  information   set  forth  in  this   registration   statement.
                  Notwithstanding  the  foregoing,  any  increase or decrease in
                  volume of  securities  offered (if the total  dollar  value of
                  securities offered would not exceed that which was registered)
                  and any  deviation  from the low or high end of the  estimated
                  maximum  offering  range  may  be  reflected  in the  form  of
                  prospectus  filed with the Commission  pursuant to Rule 424(b)
                  (Section 230.424(b) of 17 C.F.R.) if, in the aggregate,

                                      II-2





                  the changes in volume and price  represent  no more than a 20%
                  change in the maximum  aggregate  offering  price set forth in
                  the  "Calculation of Registration  Fee" table in the effective
                  registration statement; and

         (iii)    To include any material  information  with respect to the plan
                  of distribution not previously  disclosed in this registration
                  statement or any material  change to such  information in this
                  registration statement;

         provided,  however, that subparagraphs (i) and (ii) do not apply if the
         information  required to be included in a  post-effective  amendment by
         those  paragraphs  is contained in the  periodic  reports  filed by the
         Registrant  pursuant to Section 13 or Section  15(d) of the  Securities
         and  Exchange  Act of 1934 that are  incorporated  by reference in this
         registration statement.

         (2)      That for the purpose of  determining  any liability  under the
                  Securities  Act of 1933,  each such  post-effective  amendment
                  shall be deemed to be a new registration statement relating to
                  the  Securities  offered  herein,  and  the  offering  of such
                  Securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

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

(b)      Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be permitted  to  directors,  officers and  controlling
         persons of the  Registrant  pursuant to the  foregoing  provisions,  or
         otherwise,  the  Registrant has been advised that in the opinion of the
         Securities  and Exchange  Commission  such  indemnification  is against
         public   policy   as   expressed   in  such  Act  and  is,   therefore,
         unenforceable.

(c)      The undersigned registrant hereby undertakes that:

             (1) For purposes of determining  any liability under the Securities
         Act of 1933, the information  omitted from the form of prospectus filed
         as part of this  Registration  Statement in reliance upon Rule 430A and
         contained in a form of prospectus filed by the Company pursuant to Rule
         424(b)(1) or (4) or 497(h) under the  Securities Act shall be deemed to
         be part of this  Registration  Statement as of the time it was declared
         effective; and

             (2) For purposes of determining  any liability under the Securities
         Act of 1933,  each  post-effective  amendment  that  contains a form of
         prospectus shall be deemed to be a new registration  statement relating
         to the securities offered therein,  and the offering of such securities
         at that  time  shall be  deemed to be the  initial  bona fide  offering
         thereof.

                                      II-3


                                   SIGNATURES
