                               PROSPECTUS SUMMARY


                             ProtoSource Corporation


Our Business.............       ProtoSource Corporation's operations are
                                conducted through it's psnw.com division, which
                                is an Internet Service Provider based in Fresno,
                                California. In 2001, the division refocused its
                                strategy away from dial-up access into three new
                                services:

                                   o    high-speed Internet access reselling
                                        ADSL/SDSL;
                                   o    web design, development and hosting for
                                        small and medium-sized businesses; and
                                   o    outsourced technical support for other
                                        ISPs.

                                On December 18, 2001, we announced that we had
                                signed a binding Term Sheet to acquire Agence
                                21, a development-stage high-end photography
                                distribution company. The acquisition is subject
                                to a number of conditions, including the
                                approval by stockholders of each of the
                                companies.

                                via SDSL and private lines. We also offer Web

                                  RISK FACTORS

     Investing in our securities will provide you with an equity ownership
interest in ProtoSource. As one of our shareholders, your investment will be
subject to risks inherent in our business. If any of the following risks
actually occur, our business could be harmed. In that event, the trading price
of our shares might decline, and you could lose all or part of your investment.
You should carefully consider the following factors as well as other information
contained in this prospectus before deciding to invest in shares of our
securities. An investment in our securities involves a high degree of risk.

Risks Related To Our Business And Industry


We have a history of operating losses and we expect these losses to continue.

     We have experienced significant losses. We expect to continue to incur
significant losses for the foreseeable future. For the past five years, we have
funded our operations with the proceeds from three public offerings and various
private placements. We incurred net losses of approximately $1,293,640 and
$5,206,198 for the years ended December 31, 1999 and 2000, respectively, and
$9,860,312 for the nine months ended September 30, 2001. We have an accumulated
deficit of $23,123,284 at September 30, 2001. We expect our expenses to increase
as we expand our business. We cannot assure you that our revenues will increase
as a result of our increased spending. If revenues grow more slowly than we
anticipate, or if operating expenses exceed our expectations, we may not become
profitable. Even if we become profitable, we may not be able to sustain our
profitability.

We have a limited history of owning and operating our acquired businesses on a
consolidated basis, which could result in ineffective management of these
businesses.

     There can be no assurance that we will be able to meet performance
expectations or successfully integrate our acquired businesses on a timely basis
without disrupting the quality and reliability of service to our customers or
diverting management resources. If we complete our proposed acquisition of
Agence 21, our business will change dramatically and we will face additional
challenges. Our growth has placed and will continue to place a significant
strain on management, our financial resources, and on our information, operating
and financial systems. If we are unable to manage this growth effectively, it
may have an adverse effect on our business, financial condition and results of
operations.

Our efforts to concentrate our psnw.com business in commercial accounts may be
unsuccessful resulting in significant financial losses.

     Because acquisition of monthly residential accounts has required excessive
marketing costs in relation to revenue expectations, we have elected to cease
advertising and other marketing expenses directed towards that business. As a
consequence, we are concentrating our efforts to obtain commercial accounts,
which we believe can be profitable. If we are unable to obtain a sufficient
number of commercial accounts or that business is not profitable as we project,
our business, financial conditions and results of operations.

If we are unable to respond to rapidly changing technology and process
development, we may not be able to compete effectively.

     Rapidly changing technology and continuing process development characterize
the market for our products and services. The future success of our business
will depend in large part upon our ability to maintain and enhance our
technological capabilities, to develop and market products and services that

                                       2



meet changing customer needs, and to successfully anticipate or respond to
technological changes on a cost-effective and timely basis. In addition, the
Internet industry could in the future encounter competition from new or revised
technologies that render existing technology less competitive or obsolete or
that reduce the demand for our services. There can be no assurance that we will
effectively respond to the technological requirements of the changing market. To
the extent we determine that new technologies and equipment are required to
remain competitive, the development, acquisition and implementation of such
technologies and equipment may require us to make significant capital
investments. There can be no assurance that capital will be available for these
purposes in the future or that investments in new technologies will result in
commercially viable technological processes.

Our future indebtedness could adversely affect our financial health and severely
limit our ability to plan for or respond to changes in our business.

     We plan to incur indebtedness from time to time to finance acquisitions or
capital expenditures or for other purposes. This debt could have adverse
consequences for our business, including:

     o    We will be more vulnerable to adverse general economic conditions;

     o    We will be required to dedicate a substantial portion of our cash flow
          from operations to repayment of debt, limiting the availability of
          cash for other purposes;

     o    We may have difficulty obtaining additional financing in the future
          for working capital, capital expenditures, acquisitions, general
          corporate purposes or other purposes;

     o    We may have limited flexibility in planning for, or reacting to,
          changes in our business and industry;

     o    We could be limited by financial and other restrictive covenants in
          our credit arrangements in our borrowing of additional funds; and

     o    We may fail to comply with the covenants under which we borrowed our
          indebtedness, which could result in an event of default. If an event
          of default occurs and is not cured or waived, it could result in all
          amounts outstanding, together with accrued interest, becoming
          immediately due and payable. If we were unable to repay such amounts,
          the lenders could proceed against any collateral granted to them to
          secure that indebtedness.

If Internet usage does not continue to grow, we may not be able to continue our
business plan resulting in a curtailment or cessation of operations.

     Widespread use of the Internet is a relatively recent phenomenon. Our
future success depends on continued growth in the use of the Internet and the
continued development of the Internet as a viable commercial medium. We cannot
be certain that Internet usage will continue to grow at or above its historical
rates or that extensive Internet content will continue to be developed or be
accessible at no or nominal cost to users. If Internet use does not continue to
grow or users do not accept our products and services, our business could be
adversely affected and as a result the price of our common stock may decline.

                                       3



We face risks of claims from third parties for intellectual property
infringement and other matters that could adversely affect our business.

     Our services operate in part by making Internet content and cable TV
programming available to our users. This creates the potential for claims to be
made against us, either directly or through contractual indemnification
provisions with third parties. Claims might, for example, be made for
defamation, negligence, copyright, trademark or patent infringement, personal
injury, invasion of privacy or upon other legal theories. Any claims could
result in costly litigation and be time consuming to defend, divert management's
attention and resources, cause delays in releasing new or upgraded existing
services or require us to enter into royalty or licensing agreements. Royalty or
licensing agreements, if required, may not be available on acceptable terms, if
at all.

     Litigation regarding intellectual property rights is common in the Internet
and software industries. We expect that Internet technologies and software
products and services may be increasingly subject to third-party infringement
claims as the number of competitors in our industry segment grows and the
functionality of products in different industry segments overlaps.

     There can be no assurance that our services do not infringe the
intellectual property rights of third parties. A successful claim of
infringement against us and our failure or inability to license the infringed or
similar technology could adversely affect our business, financial condition and
results of operations.

We may incur liabilities for the activities of users of our service resulting in
unanticipated expenses.

     The law relating to the liability of providers of online services for
activities of their users is currently unsettled and could damage our business.
We do not carry insurance that will indemnify us for all liability for
activities of our users. Our advertisers' Websites may contain text, images or
information that could infringe third-party copyrights, trademarks or other
intellectual property rights. We cannot assure you that we will successfully
avoid civil or criminal liability for unlawful activities carried out by users
of our service. The imposition upon us of potential liability for unlawful
activities of users of our service could require us to implement measures to
reduce our exposure to such liability, which may require us, among other things,
to spend substantial resources or to discontinue certain service offerings. Any
costs incurred as a result of such liability or asserted liability could damage
our business.


Risks Related To This Offering and Our Common Stock

Sales of our shares by the selling stockholders may depress our stock price.

     Our selling stockholders may offer, from time to time, up to 1,331,230
shares of our common stock for sale by this prospectus. Sale of a substantial
number of shares of our common stock in the public market by our selling
stockholders could depress the market price of our common stock and could impair
our ability to raise capital through the sale of additional equity securities.

The exercise of our outstanding warrants and options may depress our stock
price.

     We currently have 3,511,000 warrants and options to purchase shares of our
common stock outstanding. The exercise of warrants and/or options by a
substantial number of holders within a relatively short period of time could
have the effect of depressing the market price of our common stock and could
impair our ability to raise capital through the sale of additional equity
securities.

                                       4



We may experience variability in our operating results, which could negatively
impact the price of our shares.

     Our annual and quarterly results have fluctuated in the past. The reasons
for these fluctuations may similarly affect us in the future. Prospective
investors should not rely on results of operations in any past period to
indicate what our results will be for any future period. Our operating results
may fluctuate in the future as a result of many factors, including:

     o    variations in the timing and volume of customer orders;

     o    introduction and market acceptance of our new products;

     o    changes in demand for our existing products;

     o    the accuracy of our forecasts of future requirements;

     o    changes in competitive and economic conditions generally or in our
          markets; and

     o    the timing of, and the price we pay for, acquisitions and related
          integration costs.

     Any of these factors or a combination of these factors could have a
material adverse effect on our business, financial condition and results of
operations.

We may need additional capital that could dilute the ownership interest of
investors.

     We require substantial working capital to fund our business. If we raise
additional funds through the issuance of equity, equity-related or convertible
debt securities, these securities may have rights, preferences or privileges
senior to those of the rights of holders of our common stock and they may
experience additional dilution. We cannot predict whether additional financing
will be available to us on favorable terms when required, or at all. Since our
inception, we have experienced negative cash flow from operations and expect to
experience significant negative cash flow from operations in the future. The
issuance of additional common stock by our management, may have the effect of
further diluting the proportionate equity interest and voting power of holders
of our common stock, including investors in this offering.

Our securities are thinly traded and the limited liquidity in our securities
could be adversely affected with resulting decreases in the price of our shares.

     The trading market price of our common stock may decline below its current
price. Our common stock is currently very thinly traded on The Nasdaq SmallCap
Market. An active public market for our common stock may not develop or be
sustained during or after this offering. The additional shares made available
for sale in the market as a result of this offering may depress the price of our
common stock.

We have been notified by The Nasdaq Stock Market that our common stock will be
delisted from trading on the Nasdaq SmallCap Market. We have appealed this
decision, but the delisitng of our common stock from trading on the Nasdaq
SmallCap Market will have a depressive effect on the price of the stock.

     On December 5, 2001, we received a Nasdaq Staff Determination that we fail
to comply with either the net tangible assets or stockholders' equity
requirements for continued listing on the Nasdaq SmallCap Stock Market, as set
forth in Marketplace Rule 4310(c)(2)(b) and that our securities are, therefore,

                                       5



subject to delisting from the Nasdaq SmallCap market. We requested an oral
hearing before the Nasdaq Listing Qualifications Panel to review the Staff
Determination, which hearing took place on January 17, 2002. There can be no
assurance the Panel will grant our request for continued listing. If our
securities are delisted, quotations for our common stock will be available on
the Over-The-Counter Electronic Bulletin Board. In the absence of at least
$5,000,000 of net tangible assets or a stock price in excess of $5.00 per share,
trading in our common stock would be subject to Rule 15c2-6 and Rules 15g-2
through 15g-9 under the Securities Exchange Act of 1934, requiring additional
pricing and compensation disclosures to be made to customers. These rules
require, among other things, that any broker engaging in a transaction in our
securities provide its customers with a risk disclosure document, disclosure of
market quotations, if any, disclosure of the compensation of the broker and its
salespersons in the transaction, and monthly account statements showing the
market values of our securities held in the customer's accounts. The brokers
must provide bid and offer quotations and compensation information before making
any purchase or sale of a penny stock and also provide this information in the
customer's confirmation. Generally, brokers may be less willing to execute
transactions in securities subject to the "penny stock" rules. This may make it
more difficult for investors to dispose of our common stock and cause a decline
in the market value of our stock.

The number and percentage of shares beneficially owned is determined in
accordance with Rule 13d-3 of the Securities Exchange Act of 1934, and the
information is not necessarily indicative of beneficial ownership for any other
purpose. Under such rule, beneficial ownership includes any shares as to which
the selling stockholder has sole or shared voting power or investment power and
also any shares which the selling stockholder has the right to acquire within 60
days.

The percentage interest of each selling stockholder is based on the number of
shares of common stock beneficially owned by such stockholder divided by the sum
of the outstanding shares of common stock (as of February 8, 2002).






                                       10



                              PLAN OF DISTRIBUTION

     Sales of the shares may be effected by or for the account of the selling
stockholders from time to time in transactions (which may include block
transactions) on the Nasdaq SmallCap Market, in negotiated transactions, through
a combination of such methods of sale, or otherwise, at fixed prices that may be
changed, at market prices prevailing at the time of sale or at negotiated
prices. The selling stockholders may effect such transactions by selling the
shares directly to purchasers, through broker-dealers acting as agents of the
selling stockholders, or to broker-dealers acting as agents for the selling
stockholders, or to broker-dealers who may purchase shares as principals and
thereafter sell the shares from time to time in transactions (which may include
block transactions) on the Nasdaq SmallCap Market, in negotiated transactions,
through a combination of such methods of sale, or otherwise. In effecting sales,
broker-dealers engaged by a selling stockholder may arrange for other
broker-dealers to participate. Such broker-dealers, if any, may receive
compensation in the form of discounts, concessions or commissions from the
selling stockholders and/or the purchasers of the shares for whom such
broker-dealers may act as agents or to whom they may sell as principals, or both
(which compensation as to a particular broker-dealer might be in excess of
customary commissions).

     The selling stockholders and any broker-dealers or agents that participate
with the selling stockholders in the distribution of the shares may be deemed to
be "underwriters" within the meaning of the Securities Act of 1933. Any
commissions paid or any discounts or concessions allowed to any such persons,
and any profits received on the resale of the shares purchased by them may be
deemed to be underwriting commission or discounts under the Securities Act of
1933.

     We have agreed to bear all expenses of registration of the shares other
than legal fees and expenses, if any, of counsel or other advisors of the
selling stockholders. The selling stockholders will bear any commissions,
discounts, concessions or other fees, if any, payable to broker-dealers in
connection with any sale of their shares.

                                  LEGAL MATTERS

     The valid issuance of the shares of common stock offered hereby has been
passed upon for ProtoSource by Sichenzia Ross Friedman Ference LLP, New York,
New York.

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

     The following table shows the estimated expenses of the issuance and
distribution of the securities offered hereby (all such expenses will be borne
by ProtoSource Corporation):

     Registration fee.......................................   $   303.00
     Legal fees and expenses................................     2,500.00
     Accounting fees and expenses...........................     1,500.00
         Miscellaneous, including Nasdaq listing fees.......       697.00


              Total.........................................   $    5,000


ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Our Articles of Incorporation provide that liability of directors to us for
monetary damages is eliminated to the full extent provided by California law.
Under California law, a director is not personally liable to us or our
stockholders for monetary damages for breach of fiduciary duty as a director
except for liability arising from (i) any breach of the director's duty of
loyalty to us or our shareholders; (ii) acts or omissions not in good faith or
that involve intentional misconduct or a knowing violation of law; (iii)
authorizing the unlawful payment of a dividend or other distribution on our
capital stock or the unlawful purchases of our capital stock, or (iv) any
transaction from which the director derived any improper personal benefit.

     The effect of this provision in the Articles of Incorporation is to
eliminate the rights of us and our stockholders (through stockholders'
derivative suits on behalf of us) to recover monetary damages from a director
for breach of the fiduciary duty of care as a director (including breaches
resulting from negligent or grossly negligent behavior) except in the situations
described above. This provision does not limit or eliminate the rights of any
stockholder or us to seek non-monetary relief such as an injunction or
rescission in the event of a breach of a director's duty of care or any
liability for violation of the federal securities laws.

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






ITEM 16. EXHIBITS

     The exhibits filed as part of this Registration Statement are as follows:

     Number    Description
     ------    -----------


     5.1       Opinion of Sichenzia Ross Friedman Ference LLP regarding legality
               of securities being registered.

     23.1      Consent of Sichenzia Ross Friedman Ference LLP (included in its
               opinion filed as Exhibit 5.1).

     23.2      Consent of  Angell & Deering.


ITEM 17. UNDERTAKINGS

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     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 its Certificate of Incorporation, its Bylaws, or
otherwise, the Registrant has been advised that in the opinion of the Securities
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. If a claim for
indemnification against such liabilities (other than the payment of the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against a public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

     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 to:

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

               (ii) 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 the 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 and of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the effective registration
          statement;

                                      II-2



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

provided, however, that paragraph (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is incorporated
by reference from periodic reports filed by the registrant pursuant to section
13 or section 15(d) of the Securities Exchange Act of 1934.

          (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 therein, 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 securities being registered which remain unsold at the termination of
the offering.




                                      II-3



                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
