1.   Nature of Operations and Summary of Significant Accounting Policies

     Nature of operations - ProtoSource Corporation, formerly SHR Corporation
     doing business as Software Solutions Company (the "Company"), was
     incorporated on July 1, 1988, under the laws of the state of California.
     Until May 1, 2002, the Company was an Internet service provider (ISP). The
     Company provided dial-up Internet access, web hosting services and web
     development services. The Company entered into an agreement on May 1, 2002
     to sell substantially all of the assets pertaining to the ISP to Brand X
     Networks, Inc. (see Note 3). Effective January 1, 2004, the Company
     acquired P2i Newspaper, Inc. (see Note 4). P2i Newspaper, Inc. is
     principally engaged in the conversion of text and graphics from print to
     interactive Web content. Its clients include newspaper groups located in
     the United States and the United Kingdom. P2i Newspaper is headquartered in
     Bethlehem, Pennsylvania and has a data conversion center located in Kuala
     Lumpur, Malaysia.

     Basis of presentation - The accompanying unaudited condensed consolidated
     financial statements of the Company are prepared in conformity with
     generally accepted accounting principles. The disclosures presented are
     sufficient, in management's opinion, to make the interim information
     presented not misleading. All adjustments, consisting of normal recurring
     adjustments, which are necessary so as to make the interim information not
     misleading, have been made. Results of operations for the three months
     ended March 31, 2006 are not necessarily indicative of the results expected
     for the full fiscal year or for any future period. It is recommended that
     this financial information be read with the complete financial statements
     included in the Company's Annual Report on Form 10-KSB for the year ended
     December 31, 2005 previously filed with the Securities and Exchange
     Commission. The accompanying condensed consolidated financial statements
     have been prepared on a going concern basis, which contemplates the
     realization of assets and the satisfaction of liabilities in the normal
     course of business. The financial statements do not include any adjustments
     relating to the recoverability and classification of recorded asset amounts
     or the amount and classification of liabilities that might be necessary
     should the Company be unable to continue as a going concern. The Company's
     continuation as a going concern is dependent upon its ability to generate
     sufficient cash flows to meet its obligations on a timely basis, to obtain
     additional financing as may be required, and to generate revenues to a
     level where the Company becomes profitable. Additionally, the Company has
     experienced extreme cash liquidity shortfalls from operations.

     The Company's continued existence is dependent upon its ability to achieve
     its operating plan. Management's plans include the following:

     o    Obtaining additional working capital through the sale of common stock
          or debt securities.

     o    The ability of P2i Newspaper to successfully implement its strategic
          plan as follows:

          P2i Newspaper's long-term business strategy is to focus on the
          processing of print content into Web content using technologically
          sophisticated, database-driven, services and solutions across multiple
          business-to-business verticals. The combination of on-target sales
          strategies, low labor costs, a well-educated labor pool fluent in
          English, and sophisticated technologies make P2i Newspaper highly
          competitive. The Company intends leveraging these competitive
          advantages in other markets over the next five years.

          P2i Newspaper is focused on increasing market share in the newspaper
          vertical and targeting government, retail, manufacturing and
          publishing verticals.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE THREE-MONTH PERIOD ENDED MARCH 31, 2006
                                   (unaudited)

1.   Nature of Operations and Summary of Significant Accounting Policies -
     Continued

          Newspaper

          o    In November 2003, P2i Newspaper made the strategic decision to
               withdraw from marketing directly to new newspaper accounts in the
               United States, but instead to focus on building partnerships to
               build sales. The Company recognized that the conversion of print
               content into Internet content was viewed by newspapers as an
               essential commodity, and as such they were motivated by price as
               much as product functionality and features.

          o    Through its partners and residual direct accounts, P2i Newspaper
               is supplying or has access to over 1,600 U.S. newspapers.

          Government

          o    The UK government has mandated that all government publications
               must also be available online within the near future. P2i
               Newspaper is working closely to maximize this opportunity.

          o    P2i Newspaper's solution has been evaluated by the city of
               Stockport in the UK and has passed the established Bobby AA
               standards. The Company continues to pursue business in this
               market sector.

          Retail

          o    P2i P2i Newspaper currently processes inserts for several
               retailers.

          o    In addition, the Company is in talks with retailer groups to
               provide the ad and special section processing that will be
               incorporated into a platform featuring newspaper content and
               retail inserts.

          o    The pricing for converting catalog and retail insert pages has
               fallen dramatically over the past 18 months. P2i Newspaper
               believes it will continue to fall and that the Company is
               perfectly positioned to establish partnerships with media
               companies with a retail focus.

          Manufacturing

          o    P2i Newspaper solutions are applicable for any business with
               large volumes of frequently updated print content that is
               appropriate for Internet distribution.

          o    Manufacturing companies are generally putting all technical
               manuals online in crude PDF format.

          o    The potential revenue opportunity is being quantified, but is
               believed to be substantial.

     If management cannot achieve the above objectives, the Company may find it
     necessary to dispose of assets, or undertake other actions as may be
     appropriate.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE THREE-MONTH PERIOD ENDED MARCH 31, 2006
                                   (unaudited)
- --------------------------------------------------------------------------------

1.   Nature of Operations and Summary of Significant Accounting Policies -
     Continued

     Principles of consolidation - The consolidated financial statements include
     the accounts of the Company and P2i Newspaper LLC, its wholly-owned
     subsidiary. All significant intercompany accounts and transactions have
     been eliminated.

     Revenue recognition - In accordance with the SEC's Staff Accounting
     Bulletin No. 104, the Company recognizes service revenue when persuasive
     evidence of an arrangement exists, services are performed and delivered
     without defect, the price of the transaction is fixed and determinable, and
     collectibility is reasonably assured.

     In general, no matter the nature of a customer's business, the Company,
     through its software technology at its production facilities, converts any
     manner of print text and print graphics to interactive web content
     accessible via the Internet. This most often is in the form of online
     advertising. (i.e., A visitor to a customer's website can, if he so
     chooses, interact with the ad because the Company's technology has made
     that possible. The interactivity often involves various links to additional
     information and possible other pertinent or interested parties or sources
     behind the genesis and purpose of the ad.) This electronically processed
     service is objective and readily verifiable by both parties immediately
     upon delivery to a customer's website.

     Only after the Company completes its conversion processing of specific
     digital data (printable text and/or graphic image files) provided by the
     customer and delivers the results as interactive, online web content
     directly to the customer's internet website(s) does the Company identify a
     measurable event for purposes of revenue recognition. The measurable,
     delivered event or unit is typically identified as a "page" (or "pages") of
     service provided to the customer, immediately usable by the customer and
     its clients at their website(s). This process service takes place daily, 52
     weeks a year, whereupon, digital files are received and processed overnight
     for morning delivery. Through contractual agreement, a price is determined
     and the customer is billed for each unit of service provided at the agreed
     upon price. Although the Company accumulates billable revenue-recognizable
     events daily, it typically waits until month end to bill for all units
     delivered during the course of that month as a convenience to its
     customers.

     If there are any identifiable problems or defect with any "page" content,
     it is typically fixed by the Company within a matter of hours. With respect
     to sales returns or credits, cancellations and warranties, the inherent
     nature of the type of services provided and the underlying processes
     employed by the Company to create and deliver completed product to its
     customers, there is no material exposure to what would be classified as
     sales returns or credits. Likewise, cancellations and or warranties are not
     significantly measurable in respect to the type of electronic product
     (Internet website content) deliverable to the Company's customers.
     Historically, there has been little to no applicable sales returns or
     credits. For these reasons, the Company has no material need or basis to
     make estimates for returns and allowances.

     Stock-based compensation - Effective January 1, 2006, the Company adopted
     Statement of Financial Accounting Standards ("SFAS") No. 123(R),
     "Share-Based Payment", using the modified prospective application
     transition method. The modified prospective application transition method
     requires compensation cost to be recognized beginning on the effective date
     (a) based on the requirements of SFAS 123R for all share-based payments
     granted after the effective date and (b) based on the requirements of SFAS
     123 for all awards granted to employees prior to the effective date of SFAS
     123R that remain unvested on the effective date. As such, prior periods
     will not reflect restated amounts. Prior to January 1, 2006, we accounted
     for all of our stock option plans in accordance with Accounting Principles
     Board Opinion No. 25, "Accounting for Stock Issued to Employees," and
     related Interpretations. No stock-based employee compensation expense
     related to stock option plans was reflected in net income or (loss) prior
     to January 1, 2006.

1.   Nature of Operations and Summary of Significant Accounting Policies -
     Continued

     Net income (loss) per basic and diluted share of common stock - Basic net
     income (loss) per share is calculated using the weighted average number of
     common shares outstanding. Diluted net income (loss) per share is computed
     on the basis of the weighted average number of common shares outstanding
     during the period increased by the dilutive effect of outstanding stock
     options using the "treasury stock" method.

     Options and warrants to purchase 1,185,000 and 2,225,000 shares of common
     stock at March 31, 2006 and 2005, respectively, were not included in the
     computation of diluted earnings per share, since their inclusion would be
     anti-dilutive or would have no effect on net income (loss) per share.

     Reclassifications - Certain reclassifications have been made to the 2005
     financial statement presentation for comparability with the 2006 financial
     statements.

2.   Recently Issued Accounting Standards

     In March 2005, the FASB issued FASB Interpretation ("FIN") No. 47,
     "Accounting for Conditional Asset Retirement Obligations". FIN No. 47
     requires an entity to recognize a liability for a conditional asset
     retirement obligation when incurred if the liability can be reasonably
     estimated. The Interpretation also clarifies that the term Conditional
     Asset Retirement Obligation refers to a legal obligation to perform an
     asset retirement activity in which the timing and/or method of settlement
     are conditional on a future event that may or may not be within the control
     of the entity. FIN No. 47 also clarifies when an entity would have
     sufficient information to reasonably estimate the fair value of an asset
     retirement obligation. FIN No. 47 has not had a material impact on our
     financial condition or results of operations.

     In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error
     Corrections", which changes the requirements for the accounting and
     reporting of a change in accounting principle. The statement requires
     retrospective application to prior period financial statements of changes
     in accounting principle, unless impracticable to do so. It also requires
     that a change in the depreciation, amortization, or depletion method for
     long-lived non-financial assets be accounted as a change in accounting
     estimate, effected by a change in accounting principle. Accounting for
     error corrections and accounting estimate changes will still be handled
     according to guidance in APB Opinion 20, "Accounting Changes", as carried
     forward in this pronouncement. The statement is effective for fiscal years
     beginning after December 15, 2005. We do not expect adoption of SFAS No.

     results of operations.

3.   Sale of ISP Division

     Effective May 1, 2002, the Company entered into an agreement to sell
     substantially all of the assets of the ISP division to Brand X Networks,
     Inc., a California Corporation, for $632,000. The assets have been held and
     operated by Brand X Networks, Inc. for its purposes since May 1, 2002, at
     which time the Company discontinued its ISP operations. On April 14, 2003,
     the Company completed a fifth amendment to the purchase agreement with
     Brand X pursuant to which the Company agreed to accept an aggregate payment
     of $632,000 for the ISP Division, less credits to Brand X of $112,686 and
     interim payments received of $34,859. Of such amount, $200,000 was due to
     the Company through the provision of services to the Company from Brand X.
     The balance was due at the rate of approximately $5,171 per month, until
     completely paid.

- --------------------------------------------------------------------------------

3.   Sale of ISP Division - Continued

     On January 1, 2004, the sale of the ISP business to Brand X closed. Under
     the terms of that agreement a promissory note of $284,455 was executed by
     Brand X to be paid in 55 equal monthly installments. This note was
     collateralized by a pledge of shares in Brand X. In addition, ProtoSource
     was entitled to appoint one person to the board of directors of Brand X for
     the duration of the agreement.

     In February 2006, still within terms of the purchase agreement, Brand X
     notified ProtoSource that it would be unable to make its next payment on
     its note payable obligation and could not then specify when the next
     payment(s) would be forthcoming. Subsequently, ProtoSource discovered that
     Brand X had become insolvent and is unable to meet its obligations to
     ProtoSource and, as a consequence, is unable to cure its now default status
     on its note payable obligation and, therefore, of the purchase agreement
     itself. ProtoSource has assessed the collectibility of the remaining note
     receivable balance of $162,582 and its unused services credit balance of
     $151,308 and has determined that collection or realization of any portion
     of these amounts is highly doubtful and their values should be written down
     to $0. As a consequence, the Company recorded a provision for Brand X's
     uncollectible note and services credit in the amount of $313,890 in 2005.
     Furthermore, in March 2006, ProtoSource agreed to the sale of the Brand X
     note to P2i, Inc. ("P2i"), a related party. Under the terms of the sale,
     P2i executed a note in favor of ProtoSource which was on the same terms and
     conditions as the original note between Brand X and ProtoSource. Brand X
     also executed a security agreement in favor of ProtoSource pursuant to
     which all of Brand X's assets are pledged to secure the obligations under
     the P2i note.

4.   Acquisition

     On February 13, 2003, the Company announced an agreement and Plan of Merger
     to acquire all of the outstanding capital stock of P2i Newspaper, Inc., a
     Delaware corporation ("P2i Newspaper") and a wholly-owned subsidiary of
     P2i, Inc., a Pennsylvania corporation ("P2i"), in exchange for the issuance
     of up to 19,383,531 shares of ProtoSource common stock and satisfaction of
     the existing P2i debt to the Company (the "Agreement").

     The 19,383,531 shares will be reduced by the number of shares equal to the
     total fees incurred to audit the financial statements of P2i or P2i
     Newspaper, divided by $0.50 (the "Adjusted Shares"). The Adjusted Shares
     shall be subject to a three-year lock-up, which may be released upon the
     stock price and volume reaching established thresholds.

     On January 1, 2004, the Company, P2i Newspaper and P2i amended the terms of
     the Agreement (the "Amendment"). Pursuant to the terms of the Amendment, in
     exchange for all of the issued and outstanding shares of P2i Newspaper, the
     Company issued 193,836 shares of series B preferred stock (the "Preferred
     Stock"), which shares shall be reduced by the total fees incurred to audit
     the financial statements of P2i or P2i Newspaper, divided by $50. Each
     share of Preferred Stock is exchangeable for 100 shares of the Company's
     common stock at any time after the Company increases its authorized number
     of shares of common stock to 100,000,000 shares.

     As part of this transaction, the Company also acquired an additional
     interest in P2i's new media business which brings its total ownership in
     P2i to 19.8%.

4.   Acquisition - Continued

     The acquisition of P2i Newspaper became effective on January 1, 2004, at
     which time P2i Newspaper became a wholly-owned subsidiary of the Company.
     P2i Newspaper is a leader in the conversion of previously created print
     advertising into interactive Web products for newspaper, magazine and mail
     order/retail catalog advertising. Clients include newspapers from the
     Gannett, Tribune and McClatchy Newspaper groups. The Company is

Results of Operations
- ---------------------

Three Months ended March 31, 2006 vs. Three Months ended March 31, 2005

Net Revenues - For the three months ended March 31, 2006 and 2005, net revenues
were $590,390 and $434,322 respectively. All revenues of the Company are
attributed to the operations of P2i Newspaper, Inc. acquired January 1, 2004.
The $156,068 increase in revenues over the previous year is largely attributable
to a sales effort that has focused on media companies within the newspaper
vertical that have a demand for the conversion of large volumes.

Operating Costs and Expenses - For the three months ended March 31, 2006,
operating expenses totaled $514,776 versus $448,510 in 2005. Higher production
expenditures necessary to meet the approximately 36% increase in sales accounted
for most of the increase in operating costs and expenses, but they fell
substantially as a percentage of sales due to higher efficiencies. Sales and
marketing, and general and administrative expenses increased $18,398, largely
due to higher payroll related costs. Administrative costs principally consist of
the Company's management office and personnel, professional fees associated with
restructuring and maintenance of the Company, and officers' and directors'
liability insurance costs.

Interest Expense - Interest expense totaled $86,355 for the three-month period
ended March 31, 2006 versus $120,226 in the same period in 2005. The interest
expense is a result of the convertible notes obtained during 2002, 2003, and
2004 to fund the operations of the Company and P2i Newspaper, pending and post
merger. A significant component of 2005's interest expense includes residual
amortization of debt issuance costs incurred during 2004. As there have been no
new debt issues since April 2004, the current period reflects no amortized
effect of historical debt issue costs.

Other Income (Charges) - In 2006, other charges included a $21,826 loss on
disposal of computer equipment.

Liquidity and Capital Resources
- -------------------------------

We assess liquidity by our ability to generate cash to fund our operations.
Significant factors that affect the management of our liquidity include: current
balances of cash, expected cash flows provided by operations, current levels of
our accounts receivable and accounts payable balances, access to financing
sources and our expected investment in equipment.

The Company generated positive cash flows from operating activities for each of
the three-month periods ending March 31, 2006 and 2005. Even though the
Company's net loss for the quarter ended March 31, 2006 was approximately
$25,000, cash flows provided by operations were approximately $75,000. In part,
this was due to non-cash charges of approximately $28,000 included in the net
loss; this consisted primarily of depreciation and amortization of approximately
$6,000 and approximately $22,000 of recorded loss on disposal of equipment.
Additionally, cash flows from operations during the quarter was impacted
positively by changes in working capital components of approximately $73,000.
Significant changes in working capital components included an increase in
working capital of approximately $93,000 related primarily to interest arising
from the Company's convertible debt obligations that was accrued but unpaid, but
this increase was offset by an approximately $46,000 decrease in available cash
resulting from the growth in the Company's accounts receivable due to the higher
level of revenues. Accounts receivable are all current, except for approximately
$7,800 which is considered to be a doubtful account.

During the quarter ended March 31, 2006, we had negative cash flows from
investing activities of approximately $45,000, due to acquisitions of equipment
and advances to directors and officers.

And during the quarter ended March 31, 2006, we used approximately $31,000 of
cash to advance funds of approximately $21,000 to a related company and for
payments on capital lease obligations of approximately $10,000.

As of March 31, 2006, we had $40,370 in cash and $515,993 in accounts receivable
and other current assets. Taken together with $3,747,234 of total current
liabilities, this resulted in a negative working capital position of $3,190,871
at March 31, 2006.

On December 14, 2001, after exploring numerous alternatives, the Company entered
into a term sheet to acquire P2i for 22,768,412 shares of our common stock.

In March 2002, the Company entered into an agreement with AAWC to act as
placement agent for the sale of convertible notes aggregating at least $300,000.
The notes are secured by certain assets of the Company and accrue interest at
10% per annum. P2i has agreed to pay all the costs and obligations incurred with
this financing. The funding was completed during March 2002 and AAWC was paid a
10% commission and a 3% non-accountable expense allowance.

On May 1, 2002, the Company entered into a conditional agreement to sell the
assets of the Fresno-based ISP business to Brand X Networks. Brand X Networks is
a privately held California-based company whose principal shareholders were
former employees of the Company. Additionally, Brand X has assumed financial and
operational responsibility for the ISP business. On April 14, 2003, the Company
completed a fifth amendment to the purchase agreement with Brand X pursuant to
which the Company has agreed to accept an aggregate payment of $632,000 for the
ISP Division, less credits to Brand X of $112,686, and the transaction closed on
January 1, 2004. Of such amount, $200,000 was to be paid through the provision
of services to the Company from Brand X. The balance was to be paid at the rate
of approximately $5,171 per month, until completely paid.

In February 2006, still within terms of the purchase agreement, Brand X notified
ProtoSource that it would be unable to make its next payment on its note payable
obligation and could not then specify when the next payment(s) would be
forthcoming. Subsequently, ProtoSource discovered that Brand X had become
insolvent and is unable to meet its obligations to ProtoSource and, as a
consequence, is unable to cure its now default status on its note payable
obligation and, therefore, of the purchase agreement itself. ProtoSource has
assessed the collectibility of the remaining note receivable balance of $162,582
and its unused services credit balance of $151,308 and has determined that
collection or realization of any portion of these amounts is highly doubtful and
that their values should be written down to $0. As a consequence of these
subsequent events, the Company recorded a provision for Brand X's uncollectible
note and services credit in the amount of $313,890 in 2005. In March 2006,
Protosource agreed to the sale of the Brand X note to P2i, Inc. ("P2i"), a
related party. Under the terms of the sale, P2i executed a note in favor of
Protosource which was on the same terms and conditions as the original note
between Brand X and Protosource. Brand X also executed a security agreement in
favor of Protosource pursuant to which all of Brand X's assets are pledged to
secure the obligations under the P2i note.

In July 2002, the Company executed its merger agreement with P2i. Concurrently,
the Company's CEO, Mr. William Conis, resigned his position as both CEO and
Director. Mr. Peter Wardle, CEO of P2i and a ProtoSource Director, became CEO of
the Company.

On September 17, 2002, the Board of Directors approved a revised term sheet
restructuring the P2i acquisition, and on January 1, 2004, this transaction
closed. Under the new terms, ProtoSource acquired the Newspaper portion of P2i,
Inc.'s business through the acquisition of specific assets which include the
entire newspaper related customer base, technology, intellectual property and
P2i's production company located just south of Kuala Lumpur, Malaysia. In
addition, key P2i employees transitioned with the business. These assets and the
key employees have been transferred to P2i Newspaper, Inc. a wholly-owned
subsidiary of P2i formed specifically for this purpose. The acquisition of P2i
Newspaper, Inc. by ProtoSource has been accounted for by the purchase method of
accounting as a reverse acquisition. For accounting purposes, P2i Newspaper,
Inc. is considered to be the acquirer and ProtoSource is the acquiree.

The number of shares of restricted common stock to be issued to P2i ("P2i,
Inc.") has subsequently been revised to 19,383,531 shares (after conversion of
the preferred stock issued as merger consideration) which will result in an
ownership of approximately 37% by the stockholders of P2i, on a fully diluted
basis assuming conversion of certain bridge loans into common stock, the balance
being held by the current stockholders of ProtoSource. After the acquisition of
P2i Newspaper, the Board of Directors of ProtoSource consists of seven members.
One member has been appointed by the investment banker, AAWC. (This appointment
must be approved by P2i but can't be unreasonably withheld.) Messrs. Wardle and
Butera will be on the Board and they shall appoint the two independent members
plus one other as long as they hold 25% or more of P2i (see below) collectively,
and P2i owns 25% or more of ProtoSource. In the event that P2i's ownership drops
below 25% but is not less than 10%, P2i shall appoint one board member. In the
event that P2i's ownership drops below 10%, P2i shall not have the right to
appoint any board member. ProtoSource and P2i both used the same investment
banker to represent them in the transaction and each will pay the investment
banker a fee based on the value of the transaction using a pre-set formula. The
investment banking fees to be paid are $406,844 by ProtoSource and $413,422 by
P2i. The amounts paid to the investment banker will be paid through the issuance
of common stock, which is restricted for a three-year period, based on an
agreed-upon value of $.50 per share at the time of signing the term sheet, or
813,688 shares for ProtoSource and 826,844 shares for P2i. The shares to be
issued for P2i's investment banking fees will be subtracted from the shares to
be issued to the P2i stockholders for the acquisition. P2i's remaining catalog
and new media business will stay with P2i. However, ProtoSource has increased
its ownership in P2i from the current 2.18% (506,225 shares) to 19.8%. The
consideration paid was the forgiveness of P2i debt to ProtoSource.

During 2002, the Company entered into an agreement with AAWC to act as a
placement agent for the sale of convertible notes aggregating $1,300,000. The
notes are secured by stock in P2i Newspaper, Inc. and accrue interest at 10% per
annum. The Company pays the cost and obligations of the first $200,000 incurred
with this financing and P2i Newspaper, Inc. has agreed to pay all remaining
costs and obligations. Through December 31, 2003, $1,225,000 in funding had been
completed. AAWC was paid a 10% commission and a 3% non-accountable expense.
Substantially all of the proceeds from these notes have been loaned to P2i
Newspaper, Inc. The loans were in the form of demand notes accruing interest at
8% per annum. These loans, with their related interest receivable, were written
off in 2003.

During May 2003, the Company entered into an agreement with Carl R. Butera for
the sale of a convertible note aggregating $200,000. The note is secured by
stock in P2i Newspaper, Inc. and accrues interest at 10% per annum.
Substantially all of the proceeds from this note have been loaned to P2i
Newspaper, Inc. The loans were in the form of a demand notes accruing interest
at 8% per annum. These loans, with their related interest receivable, were
written off in 2003.

During the twelve-month period ended December 31, 2003, the Company entered into
certain agreements with AAWC to act as a placement agent for the sale of
convertible notes aggregating $700,000. The notes are secured by stock in P2i
and accrue interest at 10% per annum. P2i has agreed to pay the related costs
and obligations. Through December 31, 2003, $600,000 in funding had been
completed; an additional $100,000 was completed during January 2004. AAWC was
paid a 10% commission and a 3% non-accountable expense. Substantially all of the
proceeds from these notes have been loaned to P2i Newspaper, Inc. The loans were
in the form of demand notes accruing interest at 8% per annum. These loans, with
their related interest receivable, were written off in 2003.

During 2004, the Company entered into certain agreements with AAWC to act as a
placement agent for the sale of convertible notes aggregating $500,000, of which
$300,000 was raised during the first and second quarters of 2004. These notes
accrue interest at 10% per annum. AAWC was paid a 10% commission and a 3%
non-accountable expense. These notes and all other notes are secured by the
assets of ProtoSource and P2i Newspaper.

On October 15, 2005, the Company entered into a 24-month term capital lease
agreement with Bankers Capital for the purchase of computer and computer related
items valued at $27,767 with monthly lease payments of $1,596 each. The lease
term expires September 14, 2007 and the residual maturity date is October 15,
2007 with a $1.00 purchase option. $3,487.38 was paid to Bankers Capital at the
start of the lease to cover the first payment, one payment held for a security
deposit, and for UCC filing and documentation fees. Company officers Peter A.
Wardle and Thomas C. Butera are personal Guarantors of this agreement.

Critical Accounting Policies and Estimates
- ------------------------------------------

Management's discussion and analysis of its financial position and results of
operations are based upon the Company's condensed consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States. The preparation of these financial
statements requires management to make estimates and assumptions that affect the
reported amounts of assets, liabilities, revenue and expenses and related
disclosure of contingent assets and liabilities. The significant accounting
policies which we believe are the most critical to aid in fully understanding
and evaluating our reported financial results include the following:

In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed Of" (and superceded in 2001 by
SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets"),
the Company recorded impairment charges of $24,000 in 2004 to reduce the
carrying value of its investment in P2i, Inc. to zero.

In accordance with SFAS No. 109, "Accounting for Income Taxes", the Company
maintains a valuation allowance of $5,560,000 as of March 31, 2006 on deferred
tax assets relating to its net operating losses which the Company has not
determined to be more likely than not realizable.

In accordance with SFAS No. 142, "Goodwill and Other Intangible Assets",
goodwill is not amortized, rather, management tests goodwill annually for
impairment in the fourth quarter.

The Company considers certain trade accounts receivable to be of doubtful
collection; accordingly, the Company has a $7,782 allowance for doubtful
accounts. The Company considers the balances of its note receivable of $162,582
and its unused services credit of $151,308 as uncollectible or unrealizable;
accordingly, a $313,890 allowance was recorded in 2005.


Item 3. CONTROLS AND PROCEDURES.

Evaluation of disclosure controls and procedures.

An evaluation was performed under the supervision and with the participation of
our management, including the chief executive officer, or CEO, who is also the
acting chief financial officer, or CFO, of the effectiveness of the design and
operation of our disclosure procedures. Based on management's evaluation as of
as of the end of the period covered by this Report, our principal executive
officer and chief financial officer has concluded that our disclosure controls
and procedures (as defined in Rules 13a-14(c) and 15d-14(c) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") were sufficiently
effective to ensure that the information required to be disclosed by us in the
reports that we file under the Exchange Act is gathered, analyzed and disclosed
with adequate timeliness, accuracy and completeness.

Changes in internal controls.

There have been no significant changes in our internal controls or in other
factors that could significantly affect these controls subsequent to the date of
the evaluation referred to above, nor were there any significant deficiencies or
material weaknesses in our internal controls. Accordingly, no corrective actions
were required or undertaken except as disclosed.
