REOFFER
PROSPECTUS
                            FOCUS ENHANCEMENTS, INC.

                         350,000 Shares of Common Stock

         This  Prospectus  relates to the offer and sale from time to time of up
to 350,000 shares (the "Shares") of common stock,  $.01 par value per share (the
"Common Stock") of FOCUS Enhancements,  Inc. (the "Company"), by Digital Vision,
Inc., (the "Selling Stockholder"),  or by its pledgees,  donees,  transferees or
other successors in interest that receive such Shares as a gift, distribution or
other non-sale  related  transfer.  The Shares were issued by the Company to the
Selling Stockholder on March 31, 1998 as partial payment for certain assets sold
by the Selling  Stockholder  to the Company (the "Sale of Assets").  The Company
will  not  receive  any  proceeds  from the sale of the  Shares  by the  Selling
Stockholder.  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  Stockholder,  or its 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 Stockholder, its 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 Stockholder, its 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 STOCKHOLDER" and "PLAN OF DISTRIBUTION."

         The Common  Stock is traded on the  Nasdaq  SmallCap  Market  under the
symbol FCSE. On June 25, 1998, the last sale price of the Company's Common Stock
as reported on the Nasdaq SmallCap Market was $2.50.

                                  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 March 31,  1998,  the  Company  had working
capital of  $5,825,071,  cash and cash  equivalents  of $1,164,624 and was fully
drawn on its line of credit (approximately  $690,000 at March 31, 1998) 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
$6,081,939 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 a Private Placement,
and in May 1998, the Company received approximately  $6,000,000 in proceeds from
the exercise of Common Stock  Purchase  Warrants  issued in connection  with the
Company's initial public 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 three months ended March 31, 1998,
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 March 31, 1998,  had an  accumulated
deficit of  $22,046,863.  The Company  incurred  net losses of  $10,772,410  and
$1,986,079  for the years ended  December 31, 1996 and 1997,  respectively.  The
Company  had net income of $364,748  and  $16,476 for the first three  months of
1997 and 1998, 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  ($690,000 was owed to the bank at March 31, 1998).  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. In March 1998,  the Company  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 Silicon Valley Bank
to  extend  the line  for an  additional  term.  The  Company  is  currently  in
discussions with another lender to refinance this line.

                                      -5-
<PAGE>
         The Company also currently owes $1.5 million to an unaffiliated  lender
pursuant to a term note that 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 the principal  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  anticipates  paying this lender with capital  raised from
recent warrant exercises.

         In the event that the Company is  unsuccessful  in refinancing its bank
line of credit or the Company is unable to pay the unaffiliated  lender 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  Two  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 is  incorporating  into all of its next  generation  PC-to-TV
video-graphics  products.  The  Company  is  relying  on an  outside  vendor  to
manufacture  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

                                      -6-
<PAGE>
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.

         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 has filed
five patent  applications and expects to file two additional patent applications
in 1998 with respect to its PC-to-TV  video-graphics  products, 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 Mac's(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,  Zenith  Electronics,  Port,  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.  In March
1998, the Company acquired  Digital Vision,  Inc., a developer of PC-to-TV video
scan  converters  and  TV-to-PC  video frame  capture  products for the personal
computer marketplace.

                                 USE OF PROCEEDS

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

                               SELLING STOCKHOLDER

         The Shares  being  offered for resale by the Selling  Stockholder  were
acquired in connection  with the Sale of Assets.  In connection with the Sale of
Assets, the Company granted the Selling Stockholder 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
Stockholder and its officers,  directors,  members, employees,  partners, agents
and each person who controls the Selling  Stockholder  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 the Selling Stockholder, the
number of shares of Common Stock beneficially  owned by the Selling  Stockholder
as of June 26,  1998 and the  number  of Shares  being  offered  by the  Selling
Stockholder.  The Shares being  offered  hereby are being  registered  to permit
public secondary trading,  and the Selling  Stockholder may offer all or part of
the Shares for resale from time to time.  However,  the Selling  Stockholder  is
under no  obligation to sell all or any portion of the Shares nor is the Selling
Stockholder obligated to sell any Shares immediately under this Prospectus.  All
information  with respect to share  ownership has been  furnished by the Selling
Stockholder. Because the Selling Stockholder may sell all or part of its Shares,
no  estimates  can be given as to the number of Shares  that will be held by the
Selling  Stockholder upon termination of any offering made hereby.  See "PLAN OF
DISTRIBUTION."

                              PLAN OF DISTRIBUTION

         The Shares may be sold or distributed  from time to time by the Selling
Stockholder or by pledgees,  donees or transferees of, or successors in interest
to, the  Selling  Stockholder,  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  Stockholder or its
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 Stockholder.  The Selling Stockholder
or its  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 Stockholder 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).   The  Selling   Stockholder  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 the Selling  Stockholder can presently
estimate  the amount of such  compensation.  The  Company  knows of no  existing
arrangements between the Selling Stockholder and any other stockholder,  broker,
dealer, underwriter or agent relating to the sale of distribution of the Shares.

         The  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 the Selling  Stockholder  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 Stockholder will sell any or
all of the shares of Common Stock offered hereunder.

                                  LEGAL MATTERS

         The  validity of the shares of Common Stock  offered  hereby was passed
upon for the Company by Sullivan & Worcester LLP, Boston,  Massachusetts  02109.
John A. Piccione,  Esq., is a partner at Sullivan & Worcester LLP. Mr.  Piccione
holds options to purchase 45,000 shares of Common Stock.


                                     EXPERTS

         The consolidated  financial statements of the Company as of and for the
year ended  December 31, 1997  appearing in the Company's  Annual Report on Form
10-KSB  for the year  ended  December  31,  1997,  have been  audited  by Wolf &

auditing.

                      DISCLOSURE OF COMMISSION POSITION ON
                 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. 33-602-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,  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;

                                      II-2
<PAGE>
         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.

laws of the State of Delaware  (the  "Company"),  and Digital  Vision,  Inc.,  a
corporation organized under Massachusetts ("DVI").

         WHEREAS:

         A. In connection  with the Purchase  Agreement of even date herewith by
and  between the Company  and DVI (the  "Purchase  Agreement"),  the Company has
agreed, upon the terms and subject to the conditions contained therein, to issue
and sell to DVI three hundred fifty thousand  (350,000)  shares of the Company's
common stock, par value $.01 per share,  unregistered  with restrictive  legends
(the "Common Stock"); and

         B. To induce DVI to execute  and deliver the  Purchase  Agreement,  the
Company has agreed to provide certain  registration  rights under the Securities
Act of 1933,  as  amended,  and the rules  and  regulations  thereunder,  or any
similar successor statute  (collectively,  the "Securities Act"), and applicable
state securities laws.

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
covenants  contained  herein  and other  good and  valuable  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and DVI
hereby agree as follows:

         1.       DEFINITIONS.

                  a. As used in this  Agreement,  the following terms shall have

<PAGE>



                  b.  Capitalized  terms used herein and not  otherwise  defined
herein shall have the respective  meanings set forth in the Securities  Purchase
Agreement.

         2.       REGISTRATION.

                  a. Mandatory Registration.  The Company shall use its diligent
business efforts to ensure the registration of the Registrable Securities by the
ninetieth  (90th) day following the date hereof.  In connection  therewith,  the
Company shall prepare, and, as soon as practicable,  but in no event later than,
on or before the  ninetieth  (90th) day  following  the date hereof (the "Filing
Date"),  file with the SEC a Registration  Statement on Form S-3 or, if Form S-3
is not  then  available,  on such  form  of  Registration  Statement  as is then
available  to  effect  a  registration  of all of  the  Registrable  Securities,
covering the resale of all of the Registrable Securities.

                  b.  Eligibility  for Form  S-3.  The  Company  represents  and
warrants that, as of the date of this agreement,  it meets the  requirements for
the use of Form S-3 for registration of the sale by Seller and any transferee or
assignee of the  Registrable  Securities  and the Company shall file all reports
required  to be filed by the  Company  with the SEC in a timely  manner so as to
maintain such eligibility for the use of Form S-3.

         3.       OBLIGATIONS OF THE COMPANY.

         In connection with the registration of the Registrable Securities,  the
Company shall have the following obligations:

                  a.  The  Company  shall  prepare  and  file  with  the SEC the
Registration Statement required by Section 2(a) as soon as practicable after the
date  hereof  (but in no event  later  than the  Filing  Date),  and cause  such
Registration Statement relating to Registrable Securities to become effective as
soon as  practicable  after such  filing,  and keep the  Registration  Statement
effective pursuant to Rule 415 at all times until such date as is the earlier of
(i) the date on which all of the Registrable  Securities have been sold and (ii)
the date on which all of the Registrable  Securities (in the reasonable  opinion
of counsel to Seller) may be immediately sold to the public without registration
or restriction pursuant to Rule 144(k) under the Securities Act or any successor
provision (the "Registration  Period"),  which Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein and all
documents  incorporated  by  reference  therein)  shall not  contain  any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein, or necessary to make the statements therein not misleading.

                  b.  The  Company  shall  prepare  and  file  with the SEC such
amendments  (including   post-effective   amendments)  and  supplements  to  the
Registration   Statement  and  the  prospectus   used  in  connection  with  the
Registration  Statement as may be necessary to keep the  Registration  Statement
effective at all times during the Registration  Period, and, during such period,
comply with the provisions of the Securities Act with respect to the disposition
of  all  Registrable  Securities  of the  Company  covered  by the  Registration
Statement until such time as all of such

                                        2
<PAGE>
Registrable  Securities  have been disposed of in  accordance  with the intended
methods  of  disposition  by  Seller  or  sellers  thereof  as set  forth in the
Registration Statement.

                  c. The Company shall furnish to Seller (i) promptly  after the
same is prepared  and publicly  distributed,  filed with the SEC, or received by
the Company,  one copy of the Registration  Statement and any amendment thereto,
each preliminary  prospectus,  final prospectus and each amendment or supplement
thereto,  and each  letter  written by or on behalf of the Company to the SEC or
the staff of the SEC regarding the registrable  securities  (including,  without
limitation,  any request to accelerate  the  effectiveness  of any  Registration
Statement or amendment thereto), and each item of correspondence from the SEC or
the  staff of the SEC,  in each case  relating  to such  Registration  Statement
(other than any portion,  if any,  thereof which contains  information for which
the  Company  has  sought   confidential   treatment),   (ii)  on  the  date  of
effectiveness of the Registration  Statement or any amendment  thereto, a notice
stating  that  the  Registration   Statement  or  amendment  has  been  declared
effective,  and  (iii)  such  number  of copies  of a  prospectus,  including  a
preliminary  prospectus,  and all  amendments and  supplements  thereto and such
other  documents as Seller may  reasonably  request in order to  facilitate  the
disposition of the Registrable Securities owned by Seller.

                  d. The Company  shall use its best efforts to (i) register and
qualify the Registrable  Securities covered by the Registration  Statement under
such other securities or "blue sky" laws of The  Commonwealth of  Massachusetts,
(ii) prepare and file such amendments (including post-effective  amendments) and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in The Commonwealth of Massachusetts;  provided,
however,  that the Company shall not be required in connection therewith or as a
condition  thereto to (a) qualify to do business  in any  jurisdiction  where it
would not  otherwise  be  required  to qualify but for this  Section  3(d),  (b)
subject itself to general taxation in any such jurisdiction,  (c) file a general
consent  to  service  of  process  in any such  jurisdiction,  (d)  provide  any
undertakings  that cause the Company  undue  expense or burden,  or (e) make any
change in its charter or bylaws,  which in each case the Board of  Directors  of
the Company  determines to be contrary to the best  interests of the Company and
its stockholders.

                  e. As promptly as  practicable  after  becoming  aware of such
event,  the Company shall notify Seller of the happening of any event,  of which
the Company has knowledge,  as a result of which the prospectus  included in the
Registration  Statement,  as then in effect,  includes an untrue  statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the  statements  therein not  misleading,  and use its best
efforts  promptly  to prepare a  supplement  or  amendment  to the  Registration
Statement  to correct such untrue  statement  or omission,  and deliver one such
supplement or amendment to Seller.

                  f. The  Company  shall use its best  efforts  to  prevent  the
issuance  of  any  stop  order  or  other   suspension  of  effectiveness  of  a
Registration  Statement,  and,  if  such an  order  is  issued,  to  obtain  the
withdrawal of such order at the earliest  practicable  moment (including in each
case by amending or  supplementing  such  Registration  Statement) and to notify
Seller of the issuance of such

                                        3
<PAGE>
order  and  the  resolution  thereof  (and  if such  Registration  Statement  is
supplemented  or amended,  deliver such number of copies of such  supplement  or
amendment to Seller as Seller may reasonably request).

                  g.  The  Company  shall  hold in  confidence  and not make any
disclosure of information  concerning  Seller provided to the Company unless (i)
disclosure  of such  information  is  necessary  to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant  to a subpoena or other order
from  a  court  or  governmental  body  of  competent  jurisdiction,  (iv)  such
information  has been made  generally  available  to the  public  other  than by
disclosure in violation of this or any other  agreement,  or (v) Seller consents
to the form and  content of any such  disclosure.  The  Company  agrees  that it
shall,  upon learning that disclosure of such information  concerning  Seller is
sought  in or by a court  or  governmental  body of  competent  jurisdiction  or
through  other  means,  give  prompt  notice  to  Seller  prior to  making  such
disclosure, and allow Seller, at its expense, to undertake appropriate action to
prevent disclosure of, or to obtain a protective order for, such information.

                  h. The Company shall comply with all  applicable  laws related
to the  Registration  Statement  and  offering  and sale of  securities  and all
applicable  rules and  regulations  of  governmental  authorities  in connection
therewith (including,  without limitation, the Securities Act and the Securities
Exchange Act of 1934, as amended,  and the rules and regulations  promulgated by
the SEC.)

         All  obligations  of the Company under this Section 3 (except for those
obligations  set forth in paragraph  (l) of this  Section 3) shall  terminate as
soon as Seller no longer owns any Registrable Securities.

         4.       OBLIGATIONS OF THE SELLER.

         In connection with the registration of the Registrable Securities,  the
Seller shall have the following obligations:

                  a. It shall be a condition precedent to the obligations of the
Company to complete the registration  pursuant to this Agreement with respect to
the Registrable  Securities of Seller,  that Seller shall furnish to the Company
such information regarding itself, the Registrable Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such  documents in connection  with such  registration  as the
Company may reasonably request.

                  b.  Seller,   by  Seller's   acceptance  of  the   Registrable
Securities,  agrees to cooperate with the Company as reasonably requested by the
Company  in  connection  with the  preparation  and  filing of the  Registration
Statement hereunder.

                                        4
<PAGE>
                  c. Seller  agrees  that,  upon  receipt of any notice from the
Company of the happening of any event of the kind  described in Sections 3(e) or
3(f), Seller will immediately  discontinue disposition of Registrable Securities
pursuant to the  Registration  Statement  covering such  Registrable  Securities
until Seller's receipt of the copies of the  supplemented or amended  prospectus
contemplated by Sections 3(e) or 3(f) and, if so directed by the Company, Seller
shall  deliver to the Company (at the  expense of the  Company) or destroy  (and
deliver to the Company a certificate of destruction) all copies in such Seller's
possession,  of the prospectus  covering such Registrable  Securities current at
the time of receipt of such notice.

         5.       EXPENSES OF REGISTRATION.

         All  reasonable  expenses  incurred in connection  with  registrations,
filings or qualifications pursuant to Section 2, including,  without limitation,
all registration, listing and qualifications fees, printers and accounting fees,
the fees and  disbursements  of counsel  for the  Company  shall be borne by the
Company.

         6.       INDEMNIFICATION.

         In the event any Registrable  Securities are included in a Registration
Statement under this Agreement:

                  a. To the extent permitted by law, the Company will indemnify,
hold harmless and defend (i) Seller, and (ii) the directors, officers, partners,
members,  employees,  agents and each  person  who  controls  Seller  within the
meaning  of  Section 15 of the  Securities  Act or Section 20 of the  Securities
Exchange  Act of 1934,  as amended  (the  "Exchange  Act"),  if any,  (each,  an
"Indemnified  Person"),  against any joint or several losses,  claims,  damages,
liabilities  or expenses  (collectively,  together with actions,  proceedings or
inquiries by any regulatory or self-regulatory  organization,  whether commenced
or  threatened,  in respect  thereof,  "Claims") to which any of them may become
subject  insofar as such Claims  arise out of or are based upon:  (i) any untrue
statement  or alleged  untrue  statement  of a material  fact in a  Registration
Statement or the omission or alleged  omission to state  therein a material fact
required  to  be  stated  or  necessary  to  make  the  statements  therein  not
misleading,  (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or  supplemented,  if the  Company  files any  amendment  thereof or  supplement
thereto with the SEC) or the omission or alleged  omission to state  therein any
material fact  necessary to make the  statements  made therein,  in light of the
circumstances  under which the statements therein were made, not misleading,  or
(iii) any violation or alleged  violation by the Company of the Securities  Act,
the Exchange  Act,  any other  applicable  securities  law,  including,  without
limitation,  any state  securities  law,  or any rule or  regulation  thereunder
relating to the offer or sale of the Registrable  Securities (the matters in the
foregoing clauses (i) through (iii) being, collectively,  "Violations"). Subject
to the  restrictions  set forth in  Section  6(c) with  respect to the number of
legal counsel, the Company shall reimburse the Seller and each other Indemnified
Person,  promptly as such expenses are incurred and are due and payable, for any
reasonable  legal  fees  or  other  reasonable  expenses  incurred  by  them  in
connection  with  investigating  or  defending  any such Claim.  Notwithstanding
anything to the contrary contained

                                        5
<PAGE>
herein, the indemnification  agreement contained in this Section 6(a): (i) shall
not apply to a Claim  arising out of or based upon a Violation  which  occurs in
reliance upon and in  conformity  with  information  furnished in writing to the
Company  by  such  Indemnified  Person  expressly  for  use in the  Registration
Statement or any such amendment  thereof or supplement  thereto;  (ii) shall not
apply to amounts paid in settlement of any Claim if such  settlement is effected
without the prior  written  consent of the Company,  which  consent shall not be
unreasonably  withheld;  and (iii) with respect to any  preliminary  prospectus,
shall not inure to the benefit of any Indemnified Person if the untrue statement
or  omission  of material  fact  contained  in the  preliminary  prospectus  was
corrected on a timely basis in the prospectus,  as then amended or supplemented,
if such corrected  prospectus was timely made available by the Company  pursuant
to Section  3(c) hereof,  and the  Indemnified  Person was  promptly  advised in
writing not to use the  incorrect  prospectus  prior to the use giving rise to a
Violation and such Indemnified  Person,  notwithstanding  such advice,  used it.
Such  indemnity  shall  remain  in  full  force  and  effect  regardless  of any
investigation  made by or on behalf of the Indemnified  Person and shall survive
the  transfer  of the  Registrable  Securities  by Seller  pursuant to Section 9
hereof.

                  b. In  connection  with any  Registration  Statement  in which
Seller is participating,  Seller agrees to indemnify,  hold harmless and defend,
to the same  extent  and in the same  manner  set  forth in  Section  6(a),  the
Company, each of its directors,  each of its officers who signs the Registration
Statement,  its  employees,  agents and each  person,  if any,  who controls the
Company  within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, and any other stockholder  selling securities  pursuant to the
Registration  Statement  or any of its  directors  or officers or any person who
controls  such  stockholder  within  the  meaning of the  Securities  Act or the
Exchange  Act  (collectively  and  together  with  an  Indemnified   Person,  an
"Indemnified Party"), against any Claim to which any of them may become subject,
under the Securities  Act, the Exchange Act or otherwise,  insofar as such Claim
arises out of or is based upon any  Violation,  in each case to the extent  (and
only  to the  extent)  that  such  Violation  occurs  in  reliance  upon  and in
conformity with written information furnished to the Company by Seller expressly
for use in connection with such Registration  Statement;  and subject to Section
6(c)  Seller  will  reimburse  any  legal or other  expenses  (promptly  as such
expenses are incurred  and are due and payable)  reasonably  incurred by them in
connection with  investigating or defending any such Claim;  provided,  however,
that the indemnity  agreement  contained in this Section 6(b) shall not apply to
amounts paid in settlement of any Claim if such  settlement is effected  without
the prior written  consent of Seller,  which  consent shall not be  unreasonably
withheld;  provided,  further,  however,  that Seller shall be liable under this
Agreement  (including  this  Section 6(b) and Section 7) for only that amount as
does not exceed the net proceeds  actually received by Seller as a result of the
sale of Registrable  Securities  pursuant to such Registration  Statement.  Such
indemnity shall remain in full force and effect  regardless of any investigation
made by or on behalf of such Indemnified Party.  Notwithstanding anything to the
contrary  contained  herein,  the  indemnification  agreement  contained in this
Section 6(b) with respect to any preliminary  prospectus  shall not inure to the
benefit of any Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary  prospectus was corrected on a timely basis in
the  prospectus,  as then amended or  supplemented,  and the  Indemnified  Party
failed to utilize such corrected prospectus.

                                        6
<PAGE>
                  c.  Promptly  after  receipt  by  an  Indemnified   Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   such  Indemnified  Person  or
Indemnified  Party shall,  if a Claim in respect  thereof is to made against any
indemnifying  party under this  Section 6, deliver to the  indemnifying  party a
written notice of the commencement  thereof,  and the  indemnifying  party shall
have the right to participate in, and, to the extent the  indemnifying  party so
desires,  jointly with any other indemnifying party similarly noticed, to assume
control  of the  defense  thereof  with  counsel  mutually  satisfactory  to the
indemnifying  party and the Indemnified  Person or the Indemnified Party, as the
case may be;  provided,  however,  that  such  indemnifying  party  shall not be
entitled to assume such defense and an Indemnified  Person or Indemnified  Party
shall have the right to retain its own counsel  with the fees and expenses to be
paid by the  indemnifying  party,  if,  in the  reasonable  opinion  of  counsel
retained by the indemnifying  party, the  representation  by such counsel of the
Indemnified  Person or  Indemnified  Party and the  indemnifying  party would be
inappropriate  due to actual or  potential  conflicts  of interest  between such
Indemnified  Person or Indemnified Party and any other party represented by such
counsel in such proceeding or the actual or potential  defendants in, or targets
of, any such action include both the Indemnified Person or the Indemnified Party
and the indemnifying  party and any such Indemnified Person or Indemnified Party
reasonably  determines  that  there  may be  legal  defenses  available  to such
Indemnified  Person or Indemnified Party which are different from or in addition
to those available to such indemnifying  party. The indemnifying party shall pay
for  only  one  separate  legal  counsel  for  the  Indemnified  Persons  or the
Indemnified Parties, as applicable,  and such legal counsel shall be selected by
Seller,  if the  Seller is  entitled  to  indemnification  hereunder,  or by the
Company, if the Company is entitled to indemnification hereunder, as applicable.
The  failure  to  deliver  written  notice to the  indemnifying  party  within a
reasonable  time of the  commencement  of any such action shall not relieve such
indemnifying  party of any liability to the  Indemnified  Person or  Indemnified
Party under this Section 6, except to the extent that the indemnifying  party is
actually  prejudiced in its ability to defend such action.  The  indemnification
required  by this  Section 6 shall be made by  periodic  payments  of the amount
thereof  during the course of the  investigation  or defense,  as such  expense,
loss, damage or liability is incurred and is due and payable.

         7.       CONTRIBUTION.

         To  the  extent  any   indemnification  by  an  indemnifying  party  is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided,  however, that
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section 6, (ii) no person  guilty of  fraudulent  misrepresentation  (within the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution  from any seller of  Registrable  Securities  who was not guilty of
such fraudulent  misrepresentation,  and (iii)  contribution  (together with any
indemnification  or other  obligations  under this  Agreement)  by any seller of
Registrable  Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

         8.       AMENDMENT OF REGISTRATION RIGHTS.

         Provisions of this Agreement may be amended and the observance  thereof
may  be  waived  (either  generally  or  in a  particular  instance  and  either
retroactively  or  prospectively),  only with written consent of the Company and
Seller.  Any  amendment or waiver  effected in  accordance  with this Section 10
shall be binding upon Seller and the Company.

         9.       MISCELLANEOUS.

                  a. A person or entity is deemed to be a holder of  Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

                  b. Any  notices  required or  permitted  to be given under the
terms of this  Agreement  shall be sent by certified or registered  mail (return
receipt  requested)  or  delivered  personally  or by  courier  or by  confirmed
telecopy,  and shall be effective  five (5) days after being placed in the mail,
if mailed, or upon receipt or refusal of receipt, if delivered  personally or by

                  c.  Failure of any party to exercise any right or remedy under
this  Agreement or otherwise,  or delay by a party in  exercising  such right or
remedy, shall not operate as a waiver thereof.

                  d.  This  Agreement  shall be  governed  by and  construed  in
accordance  with the laws of The  Commonwealth  of  Massachusetts  applicable to
contracts made and to be performed in The Commonwealth of Massachusetts.  Seller
irrevocably consents to the jurisdiction of the United States federal courts and
the state courts located in The  Commonwealth  of  Massachusetts  in any suit or
proceeding based on or arising under this Agreement and irrevocably  agrees that
all claims in  respect  of such suit or  proceeding  may be  determined  in such
courts.  Seller  irrevocably  waives the defense of an inconvenient forum to the
maintenance  of such suit or  proceeding.  Seller further agrees that service of
process upon Seller, mailed by first class mail shall be deemed in every respect
effective service of process upon Seller in any such suit or proceeding. Nothing
herein shall  affect the  Company's  right to serve  process in any other manner
permitted by law. Seller agrees that a final non-appealable judgment in any such
suit  or  proceeding   shall  be  conclusive   and  may  be  enforced  in  other
jurisdictions by suit on such judgment or in any other lawful manner.

                  e. This  Agreement and the Purchase  Agreement  (including all
schedules  and  exhibits  thereto)  constitute  the entire  agreement  among the
parties  hereto with  respect to the subject  matter  hereof and  thereof.  This

                  f.  Subject  to the  requirements  of  Section 9 hereof,  this
Agreement  shall inure to the benefit of and be binding upon the  successors and
assigns of each of the parties hereto.

                  g. The  headings  in this  Agreement  are for  convenience  of
reference only and shall not limit or otherwise affect the meaning hereof.

                  h. This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original but all of which shall  constitute one
and the same  agreement.  This  Agreement,  once  executed  by a  party,  may be
delivered to the other party hereto by facsimile  transmission of a copy of this
Agreement bearing the signature of the party so delivering this Agreement.

                  i. Each party  shall do and  perform,  or cause to be done and
performed,  all such further acts and things,  and shall execute and deliver all
such other  agreements,  certificates,  instruments and documents,  as the other
party may reasonably request in order to carry out the intent and accomplish the

Gentlemen:

         We are familiar with the  Registration  Statement on Form S-3 (the "S-3
Registration  Statement")  to which this  opinion is an exhibit,  to be filed by
FOCUS  Enhancements,  Inc., a Delaware  corporation  (the  "Company"),  with the
Securities and Exchange Commission under the Securities Act of 1933, as amended.
The S-3  Registration  Statement  relates to the  proposed  public  offering  by
Digital Vision,  Inc. (the "Selling  Stockholder")  of a total of 350,000 shares
(the "Shares") of the Company's Common Stock,  $.01 par value per share ("Common
Stock"),  issued to the Selling  Stockholder in connection  with the purchase by
the Company of certain assets from the Selling Stockholder on March 31, 1998.

         We have  acted  as  counsel  to the  Company  in  connection  with  the
preparation of the S-3 Registration  Statement,  and we have examined and relied
on  the  originals  or  copies,   certified  or  otherwise   identified  to  our
satisfaction  of all such  corporate  records  of the  Company  and  such  other
instruments   and  other   certificates  of  public   officials,   officers  and
representatives  of the  Company and such other  persons,  and we have made such
investigations of law, as we have deemed  appropriate as a basis for the opinion
expressed below. In making such examination,  we have assumed the genuineness of
all signatures,  the legal capacity of natural persons,  the authenticity of all
documents  submitted to us as originals  and the  conformity to the originals of
all documents  submitted to us as copies,  which facts we have not independently
verified. As to various facts material to the opinions set forth herein, we have
relied without  independent  verification  upon certificates of public officials
and upon facts certified to us by officers of the Company. We express no opinion
herein as to any laws other  than the  General  Corporation  Law of the State of
Delaware.

         Based upon the  foregoing,  we are of the opinion  that the Company has
corporate  power adequate for the issuance of the Shares  issuable in the manner
set forth in the S-3  Registration  Statement  and  offered  pursuant to the S-3
Registration Statement.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
S-3 Registration Statement.

                                                  Very truly yours,
