                                                             August 26, 2002


     On April 10th, 2002, Robert Hammond, the Chief Executive Officer, President
and Chairman of Partbase,  Inc.  (NASDAQ SC:  PRTS)  proposed a "going  private"
transaction  where he or a  related  entity  would pay $1.02 per share for those
shares  of  common  stock  that he did  not  already  own.  The  Offer  was at a
significant  premium to the then market  price of $0.72 per share.  Mr.  Hammond
owns 9,150,000 of the  13,977,920  shares  outstanding,  for  approximately  65%
ownership.  The  Company's  Board  of  Director's  then  constituted  a  Special
Committee  of  Directors,  Pierre  Narath,  Thomas Van Hare and Ed  McCartin  to
consider the offer presented for the proposed  transaction.  Shortly thereafter,
the Company  retained  the  services of vFinance  Investments,  Inc. to help the
Special Committee  evaluate the Fairness of the offer to shareholders and render
an opinion to the Board of Directors.

     To that end,  Employees of vFinance  visited the Company to perform on-site
due  diligence,  met with CEO and Chairman  Robert Hammond and CFO Mark Weicher,
and also meet with a second  bidder who  emerged  and made an offer of $1.22 per
share, AirOperations.com.  The vFinance team spent a considerable amount of time
speaking  with Mark  Weicher,  rounding up  information  for due  diligence  and
analysis purposes.  The vFinance team then went about the task of performing its
analysis to determine an  appropriate  value for the Company.  The first task at
hand was to define those other  companies that might be considered  "comparable"
to  Partsbase.  In reality,  PRTS is  somewhat  unique in the manner in which it
operates,  enabling  e-commerce  for the aviation  industry,  allowing  vendors,
manufacturers  and  end-users  to post,  sell and  trade  parts for all kinds of
aircraft at a special portal. The model is  subscription-based,  with buyers and
sellers  paying a fee for the  right  to post on the  website,  and the  Company
receives a small piece of each transaction as well.

     As  mentioned,  this  model  differs  in that no parts are ever  taken into
inventory,  so the  company  cannot be  compared  with  traditional  vendors  of
aircraft  parts.  We then  decided  that a  comparable  analysis  should look at
companies  that  attempt  to  facilitate  e-commerce  within  specific  industry
segments,  or are online databases that can be searched and data mined. Attached
is  Exhibit A, which is a listing  of those  companies  that fit the  parameters
defined above. The Companies cut across many different industry  segments,  vary
in size in terms of market capitalization and revenues. Some demographics of our
selected sample are in order.

     A total of eleven (11) companies that we believe fit our defined parameters
were included in our comparable sample. They range in market capitalization size
from $2.2 million to $619.3 million,  with a mean market  capitalization of $100
million.  The  majority of the  companies  fall  within the venue of  E-commerce
enabling, with no specific industry focus, while Healthcare E-commerce companies
composed the next largest  segment.  Automotive  E-commerce  and  Database/Print
Media round out the companies in the sample. The range of year-end 2001 revenues
generated by this group varied from $1.43 million to $148  million,  with a mean
of $41.6 million,  as compared to the $6.0 million generated by Partsbase,  Inc.
in 2001.

     Having  reviewed  the  operating   demographics  of  this  sample  set  and
determined  that Partsbase fell within the parameters of this group, we began to
set forth the basis of our  analysis.  In the end,  we settled  on 3  analytical
techniques;  Comparable  Company  Analysis,  Buy-Out/Acquisition  Analysis,  and


                                       3


Liquidation Analysis, to arrive at what we felt was a proper valuation range for
PartsBase, Inc.

     In terms of  Comparable  Analysis,  we saw that it would not be possible to
perform the analysis  using  earnings or cashflow as the valuation  methodology,
mainly because most of these  companies are currently not generating  earning or
cashflow.  As such, we determined  that we would derive  multiples  based off of
Market  Price and  Enterprise  Value.  These two items would be compared to each
company's  Revenue,  EBITDA  (Earnings before  Interest,  Taxes,  Depreciation &
Amortization),  EBIT (Earnings before Interest and Taxes) and Net Assets.  These
multiples,  once derived from our sample set, would be the "Industry  Multiples"
that would be  applied  against  PRTS's  operating  statistics  to arrive at its
value.  Based on this  analysis,  the range of per share prices worked out to be
$1.44 to $2.05 per share. (See Exhibit B )

     We then went back to our  sample set and  determined  that 2  companies  in
particular,  FreeMarkets,  Inc., and Neoforma, Inc. were skewing the analysis as
they were much larger in terms of market  capitalization  than the others,  even
though they were similar in operating  methods.  We then decided to evaluate the
comparables  and price ranges with them out of the analysis (See Exhibit C), and
the effect  was  drastic.  The range fell t o$1.02 to $1.65 per share,  when the
analysis reflected those companies closer in market  capitalization to PartBase.
In the end, we will make use of both sets of comparable  analyses,  as each is a
valid manner by which to examine PRTS's value.

     After examining the selected universe of somewhat comparable companies,  we
analyzed  buyouts of similar sized companies (See Attached Exhibit D) in related
sectors. It shows the transaction prices, market capitalizations,  premiums paid
above the market price from the date of offer,  and the amount of cash listed on
the target  company's book as a percentage of it's market  capitalization.  Four
target  companies were examined that were similar to slightly  larger in size in
market  capitalization to PartsBase,  Inc. The buyouts ranged in size from $10.8
million to $93.5 million, with two structured as all stock transactions,  one as
a combination of cash and stock,  and the final one as all cash. Given the small
size of the sample (many e-commerce  enabling companies went bankrupt during the
Dot.com  bust,  with the assets  being  acquired  at fire sale  prices.),  it is
difficult to infer any  statistical  trends from the data,  as each  transaction
differs  significantly.  One thing  that does come  through  in the data is that
transactions do occur at a value less than the actual cash listed on the balance
sheet.  In those  scenarios  where the enterprise  value,  defined as the market
value of the  company's  equity plus debt less the cash on the balance  sheet is
negative, the implication is that the operating business should not be valued on
a going concern basis.  It cannot be ascertained if the  implication is due to a
flawed operating model, ineffective management, slower than expected development
of industry fundamentals,  or lack of demand for product reflective of decreased
spending for technology  investments.  Irrespective of the reason,  the analysis
indicates  that the mean  premium to market price paid for the  acquisitions  in
this sample set was 54%,  which applied to the initial  market  price,  yields a
price of $1.11.  Applying the mean  percentage of balance sheet cash to offering
price (75%) we arrive at a price of $1.28, effectively making the range $1.11 to
$1.28 for our sample buyout set.

     We touched upon the concept of negative  enterprise value, where the market
value of the debt and  equity  less  cash on the  balance  sheet  was  negative,
implying  little or no  operating  value  should be  assigned  to the  Operating
Business.  While we do not attempt to evaluate the merits of the PRTS  operating
model,  the following  analysis assumes that the assets of the Company are to be
liquidated,  and  we  attempt  to  assign  values  and  arrive  at a  per  share
Liquidation price. For the basis of our analysis, noted as Exhibit E, we decided
to take a conservative  approach and look at the value of the assets on a "worst
case" scenario, typified when one is a motivated seller, in a low demand market.
We started by examining  the assets on the Balance  sheet as of 3/31/02 and made
certain assumptions to the recoverability of value in that asset.  Regarding the
Cash on the Balance Sheet, we assumed that Current  Liabilities would be paid in
full, and a contingency  reserve to settle outstanding leases and other expenses
such as D&O  insurance  would reduce the amount  available to  Shareholders.  We
estimated that amount at  $20,389,000.  The greatest offset to Cash was Deferred
Revenue,  which was cash  collected  without the  Company  having  provided  the
service.  As a  corollary  of this item,  we assumed  that once  contracts  were
invalidated,  a  significant  portion  of the  Accounts  Receivable  may  become
uncollectible.  We estimated a 50%  collection  rate on the A/R,  adding another
$548,000 to the value.  We also  assumed no recovery  of prepaid  expenses,  and
listed $0 for that item.


                                       8



     Next, we moved on to examine the  Longer-term  assets on the balance sheet,
which  included  Furniture  and Fixtures,  Automobiles,  Equipment and Software.
Recovery  of value on these  items is far more  difficult,  as the glut of these
forms of hard assets,  resulting  from numerous  "Dot.com",  Telecom,  and other
bankruptcies,  has caused  prices to drop  precipitously.  We  basically  viewed
recovery on the hard assets at  approximately  $0.20 on the dollar on a weighted
average basis, or $464,000,  with minimal amounts for furniture and fixtures and
software, and greater amounts on Equipment and automobiles.  We did not assign a
recovery value on Restricted Cash, which backs an irrevocable  Letter of Credit,
and Other Assets.  The total of these amounts work out to be $21,401,000,  which
equates to approximately $1.53 per share.

     We have examined 3 valuation methodologies, with 2 iterations on Comparable
Analysis,  and arrived at ranges of $1.44 to $2.05 for Comparables which include
large market cap competitors, $1.02 to $1.65 for Comparables of like market cap,
$1.11  to$1.28 for Buy Out  valuations,  and $1.53 under a possible  Liquidation
scenario.  The average of these  methodologies  is a range of $1.28 per share to
$1.63 per share,  which we are prepared to represent to the Special Committee as
the acceptable  range of offers to be considered  for a possible  acquisition or
going private transaction for Partsbase ,Inc.


     Pursuant  to a request by the  Special  Committee,  and in answer to a 13-D
filing by two of the Company's largest institutional holders, which collectively
held 10.5% of the shares  outstanding,  vFinance  was asked to arrive at a value
for the portal  assets  and  collectively  work with the  Special  Committee  to
solicit bids for those assets to determine if the  combination  of an asset sale
with a  distribution  of cash from the  company  may result in a larger  overall
value with a greater degree of certainty to shareholders rather than an outright
sale to any one bidder.

     We  valued   the   portal   assets   using  two   methodologies;   Specific
identification  of portal  assets,  and  valuation of the portal assets based on
subscription  revenues.  The  subscription  valuations  were base on a review of
trailing twelve months and a forecast for a forward  looking twelve months.  The
figure  arrived  at for the  portal  based on  balance  sheet  assets,  was $3.4
million,  while the range of values  based on  subscription  revenue was $3.6 to
$4.0 million.

     We then circled back with a number of interested  parties who had expressed
interest in the portal  assets.  One bid was submitted by Harold van Arnem and a
another by  "Company  X". The offer by van Arnem was listed as $4  million,  but
when netted against A/R and working  capital  givebacks,  equaled  approximately
$1.5  million,  and would have  required that the Company hold an 18 month note.
The second  offer by "Company X" was put at a range of $3 - $4 million,  with no
financing  contingencies,  but was subject to  adjustments  upon  completed  due
diligence.  As  such,  we  advised  the  Special  Committee  that if in It's own
opinion,  it could not be assured of getting  additional value on an asset sale,
it should  conclude  that it was not in the best  interest  of  shareholders  to
pursue this path.

     Finally,  a revised offer from Robert  Hammond has been  submitted at $1.41
per share,  with certain  contingencies,  which we feel comfortable  enough with
that we will opine is fair to shareholders.

 Report of vFinance Investment, Inc. dated June 24, 2002  Prepared  by  vFinance
                                Investments, Inc.

                                Exhibit (c) (4)


vFinance, Investments, Inc.


  Report to the Special Committee of the Board of Directors of PARTSBASE, INC.


                                                                  June 24, 2002


     On April 10th, 2002, Robert Hammond, the Chief Executive Officer, President
and Chairman of Partbase,  Inc.  (NASDAQ SC:  PRTS)  proposed a "going  private"
transaction  where he or a  related  entity  would pay $1.02 per share for those
shares  of  common  stock  that he did  not  already  own.  The  Offer  was at a
significant  premium to the then market  price of $0.72 per share.  Mr.  Hammond
owns 9,150,000 of the  13,977,920  shares  outstanding,  for  approximately  65%
ownership.  The  Company's  Board  of  Director's  then  constituted  a  Special
Committee  of  Directors,  Pierre  Narath,  Thomas Van Hare and Ed  McCartin  to
consider the offer presented for the proposed  transaction.  Shortly thereafter,
the Company  retained  the  services of vFinance  Investments,  Inc. to help the
Special Committee  evaluate the Fairness of the offer to shareholders and render
an opinion to the Board of Directors.

     To that end,  Employees of vFinance  visited the Company to perform on-site
due  diligence,  met with CEO and Chairman  Robert Hammond and CFO Mark Weicher,
and also meet with a second  bidder who  emerged  and made an offer of $1.22 per
share, AirOperations.com.  The vFinance team spent a considerable amount of time
speaking  with Mark  Weicher,  rounding up  information  for due  diligence  and
analysis purposes.  The vFinance team then went about the task of performing its
analysis to determine an  appropriate  value for the Company.  The first task at
hand was to define those other  companies that might be considered  "comparable"
to  Partsbase.  In reality,  PRTS is  somewhat  unique in the manner in which it
operates,  enabling  e-commerce  for the aviation  industry,  allowing  vendors,
manufacturers  and  end-users  to post,  sell and  trade  parts for all kinds of
aircraft at a special portal. The model is  subscription-based,  with buyers and
sellers  paying a fee for the  right  to post on the  website,  and the  Company
receives a small piece of each transaction as well.

     As  mentioned,  this  model  differs  in that no parts are ever  taken into
inventory,  so the  company  cannot be  compared  with  traditional  vendors  of
aircraft  parts.  We then  decided  that a  comparable  analysis  should look at
companies  that  attempt  to  facilitate  e-commerce  within  specific  industry
segments,  or are online databases that can be searched and data mined. Attached
is  Exhibit A, which is a listing  of those  companies  that fit the  parameters
defined above. The Companies cut across many different industry  segments,  vary
in size in terms of market capitalization and revenues. Some demographics of our
selected sample are in order.

     A total of eleven (11) companies that we believe fit our defined parameters
were included in our comparable sample. They range in market capitalization size
from $2.2 million to $619.3 million,  with a mean market  capitalization of $100
million.  The  majority of the  companies  fall  within the venue of  E-commerce
enabling, with no specific industry focus, while Healthcare E-commerce companies
composed the next largest  segment.  Automotive  E-commerce  and  Database/Print
Media round out the companies in the sample. The range of year-end 2001 revenues
generated by this group varied from $1.43 million to $148  million,  with a mean
of $41.6 million,  as compared to the $6.0 million generated by Partsbase,  Inc.
in 2001.

     Having  reviewed  the  operating   demographics  of  this  sample  set  and
determined  that Partsbase fell within the parameters of this group, we began to
set forth the basis of our  analysis.  In the end,  we settled  on 3  analytical
techniques;  Comparable  Company  Analysis,  Buy-Out/Acquisition  Analysis,  and


                                       3


Liquidation Analysis, to arrive at what we felt was a proper valuation range for
PartsBase, Inc.

     In terms of  Comparable  Analysis,  we saw that it would not be possible to
perform the analysis  using  earnings or cashflow as the valuation  methodology,
mainly because most of these  companies are currently not generating  earning or
cashflow.  As such, we determined  that we would derive  multiples  based off of
Market  Price and  Enterprise  Value.  These two items would be compared to each
company's  Revenue,  EBITDA  (Earnings before  Interest,  Taxes,  Depreciation &
Amortization),  EBIT (Earnings before Interest and Taxes) and Net Assets.  These
multiples,  once derived from our sample set, would be the "Industry  Multiples"
that would be  applied  against  PRTS's  operating  statistics  to arrive at its
value.  Based on this  analysis,  the range of per share prices worked out to be
$1.44 to $2.05 per share. (See Exhibit B )

     We then went back to our  sample set and  determined  that 2  companies  in
particular,  FreeMarkets,  Inc., and Neoforma, Inc. were skewing the analysis as
they were much larger in terms of market  capitalization  than the others,  even
though they were similar in operating  methods.  We then decided to evaluate the
comparables  and price ranges with them out of the analysis (See Exhibit C), and
the effect  was  drastic.  The range fell t o$1.02 to $1.65 per share,  when the
analysis reflected those companies closer in market  capitalization to PartBase.
In the end, we will make use of both sets of comparable  analyses,  as each is a
valid manner by which to examine PRTS's value.

     After examining the selected universe of somewhat comparable companies,  we
analyzed  buyouts of similar sized companies (See Attached Exhibit D) in related
sectors. It shows the transaction prices, market capitalizations,  premiums paid
above the market price from the date of offer,  and the amount of cash listed on
the target  company's book as a percentage of it's market  capitalization.  Four
target  companies were examined that were similar to slightly  larger in size in
market  capitalization to PartsBase,  Inc. The buyouts ranged in size from $10.8
million to $93.5 million, with two structured as all stock transactions,  one as
a combination of cash and stock,  and the final one as all cash. Given the small
size of the sample (many e-commerce  enabling companies went bankrupt during the
Dot.com  bust,  with the assets  being  acquired  at fire sale  prices.),  it is
difficult to infer any  statistical  trends from the data,  as each  transaction
differs  significantly.  One thing  that does come  through  in the data is that
transactions do occur at a value less than the actual cash listed on the balance
sheet.  In those  scenarios  where the enterprise  value,  defined as the market
value of the  company's  equity plus debt less the cash on the balance  sheet is
negative, the implication is that the operating business should not be valued on
a going concern basis.  It cannot be ascertained if the  implication is due to a
flawed operating model, ineffective management, slower than expected development
of industry fundamentals,  or lack of demand for product reflective of decreased
spending for technology  investments.  Irrespective of the reason,  the analysis
indicates  that the mean  premium to market price paid for the  acquisitions  in
this sample set was 54%,  which applied to the initial  market  price,  yields a
price of $1.11.  Applying the mean  percentage of balance sheet cash to offering
price (75%) we arrive at a price of $1.28, effectively making the range $1.11 to
$1.28 for our sample buyout set.

     We touched upon the concept of negative  enterprise value, where the market
value of the debt and  equity  less  cash on the  balance  sheet  was  negative,
implying  little or no  operating  value  should be  assigned  to the  Operating
Business.  While we do not attempt to evaluate the merits of the PRTS  operating
model,  the following  analysis assumes that the assets of the Company are to be
liquidated,  and  we  attempt  to  assign  values  and  arrive  at a  per  share
Liquidation price. For the basis of our analysis, noted as Exhibit E, we decided
to take a conservative  approach and look at the value of the assets on a "worst
case" scenario, typified when one is a motivated seller, in a low demand market.
We started by examining  the assets on the Balance  sheet as of 3/31/02 and made
certain assumptions to the recoverability of value in that asset.  Regarding the
Cash on the Balance Sheet, we assumed that Current  Liabilities would be paid in
full, and a contingency  reserve to settle outstanding leases and other expenses
such as D&O  insurance  would reduce the amount  available to  Shareholders.  We
estimated that amount at  $20,389,000.  The greatest offset to Cash was Deferred
Revenue,  which was cash  collected  without the  Company  having  provided  the
service.  As a  corollary  of this item,  we assumed  that once  contracts  were
invalidated,  a  significant  portion  of the  Accounts  Receivable  may  become
uncollectible.  We estimated a 50%  collection  rate on the A/R,  adding another
$548,000 to the value.  We also  assumed no recovery  of prepaid  expenses,  and
listed $0 for that item.


                                       8



     Next, we moved on to examine the  Longer-term  assets on the balance sheet,
which  included  Furniture  and Fixtures,  Automobiles,  Equipment and Software.
Recovery  of value on these  items is far more  difficult,  as the glut of these
forms of hard assets,  resulting  from numerous  "Dot.com",  Telecom,  and other
bankruptcies,  has caused  prices to drop  precipitously.  We  basically  viewed
recovery on the hard assets at  approximately  $0.20 on the dollar on a weighted
average basis, or $464,000,  with minimal amounts for furniture and fixtures and
software, and greater amounts on Equipment and automobiles.  We did not assign a
recovery value on Restricted Cash, which backs an irrevocable  Letter of Credit,
and Other Assets.  The total of these amounts work out to be $21,401,000,  which
equates to approximately $1.53 per share.

     We have examined 3 valuation methodologies, with 2 iterations on Comparable
Analysis,  and arrived at ranges of $1.44 to $2.05 for Comparables which include
large market cap competitors, $1.02 to $1.65 for Comparables of like market cap,
$1.11  to$1.28 for Buy Out  valuations,  and $1.53 under a possible  Liquidation
scenario.  The average of these  methodologies  is a range of $1.28 per share to
$1.63 per share,  which we are prepared to represent to the Special Committee as
the acceptable  range of offers to be considered  for a possible  acquisition or
going private transaction for Partsbase ,Inc.
