ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS.

         Pursuant to an Agreement and Plan of Merger dated as of December 17,
2002 (the "Merger Agreement"), by and among Manhattan Pharmaceuticals, Inc.,
formerly known as Atlantic Technology Ventures, Inc. (the "Registrant"),
Manhattan Pharmaceuticals, Inc., a Delaware corporation ("MP"), and Manhattan
Pharmaceuticals Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of the Registrant ("Merger Sub"), Merger Sub merged with and into MP,
with MP remaining as the surviving company (the "Merger"). The Merger was
effective as of February 21, 2003.

         In accordance with the terms of the Merger Agreement, each outstanding
share of MP common stock automatically converted into the right to receive
approximately 12.7 shares of the Registrant's common stock. At the time of the
Merger there were 7,352,633 shares of MP common stock outstanding, requiring the
Registrant to issue approximately 93,449,584 shares of its common stock to the
former stockholders of MP. Accordingly, after giving effect to the Merger, the
conversion of the Series A Preferred Stock and the exchange of warrants, the
Registrant has 116,811,980 shares of common stock outstanding. In addition,
immediately prior to the effective time of the Merger, there were outstanding
options and warrants to purchase an aggregate of 864,280 shares of MP common
stock, which as a result of the Merger, now represent the right to purchase an
aggregate of 10,984,719 shares of the Registrant's common stock.

         David M. Tanen, a member of the Registrant's board of directors since
January 2002, was also a director of MP since its inception in August 2001. Mr.
Tanen abstained from all board actions of either the Registrant or MP relating
to approval of the Merger Agreement. Mr. Tanen is also an employee of Paramount
Capital, Inc. (together with its affiliated entities, "Paramount"), an entity
wholly-owned by Dr. Lindsay A. Rosenwald. Immediately prior the completion of
the Merger, Dr. Rosenwald beneficially owned approximately 28 percent of the
Registrant's common stock and approximately 14 percent of MP's common stock.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors
Manhattan Research Development, Inc.

We have audited the accompanying balance sheet of MANHATTAN RESEARCH
DEVELOPMENT, INC. (formerly Manhattan Pharmaceuticals, Inc.) (a development
stage company) as of December 31, 2002, and the related statements of
operations, changes in stockholders' equity (deficiency) and cash flows for the
year then ended and for the period from January 1, 2002 to December 31, 2002 as
related to the period from August 6, 2001 (date of inception) to December 31,
2002. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Manhattan Research Development,
Inc. as of December 31, 2002, and its results of operations and cash flows for
the year then ended and for the period from January 1, 2002 to December 31, 2002
as related to the period from August 6, 2001 (date of inception) to December 31,
2002, in conformity with accounting principles generally accepted in the United
States of America.

The financial statements referred to above have been prepared assuming that the
Company will continue as a going concern. As discussed in Notes 1, 2 and 10 to
the financial statements, the Company, which has suffered recurring losses from
operations, completed a merger on February 21, 2003 with Manhattan
Pharmaceuticals, Inc., which has also suffered recurring losses from operations.
The combined Company will have limited financial resources. Such matters raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are described in Note 2. The
financial statements referred to above do not include any adjustments that might
result from the outcome of this uncertainty.

                          REPORT OF WEINBERG & COMPANY

                          INDEPENDENT AUDITORS' REPORT


To the Board of Directors of:
  Manhattan Pharmaceuticals, Inc.
  (A development stage company)

We have audited the accompanying balance sheet of Manhattan Pharmaceuticals,
Inc. (a development stage company) as of December 31, 2001 and the related
statements of operations, changes in stockholders' deficiency and cash flows for
the period from August 6, 2001 (inception) to December 31, 2001. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly in all
material respects, the financial position of Manhattan Pharmaceuticals, Inc. as
of December 31, 2001, and the results of its operations and its cash flows for
the period from August 6, 2001 (inception) to December 31, 2001, in conformity
with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 9 to the
financial statements, the Company has a net loss from operations of $56,796
since inception, a negative cash flow from operating activities of $27,500 since
inception, a working capital deficiency of $56,796 and a stockholders'
deficiency of $56,796. These matters raise substantial doubt about the Company's
ability to continue as a going concern. Management's plan in regards to these
matters is also described in Note 9. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                          (A Development Stage Company)

                          NOTES TO FINANCIAL STATEMENTS


NOTE 1 - BUSINESS:
               Manhattan Research Development, Inc. (the "Company" or "Manhattan
               Research") was incorporated on August 6, 2001 under the laws of
               the State of Delaware. The Company's name was changed from
               Manhattan Pharmaceuticals, Inc. to Manhattan Research
               Development, Inc. on February 21, 2003. The Company is a
               development stage biopharmaceutical company that holds an
               exclusive world-wide, royalty-free license to certain
               intellectual property (the "Property") owned by Oleoyl-Estrone
               Developments, SL ("OED") of Barcelona, Spain (the "University").
               Oleoyl-Estrone is an orally administered small molecule that has
               been shown to cause significant weight loss in preclinical animal
               studies regardless of dietary modifications.

               On February 21, 2003, Manhattan Pharmaceuticals, Inc. (formerly
               known as "Atlantic Technology Ventures, Inc.") ("Manhattan
               Pharmaceuticals") completed a reverse acquisition of the Company.
               Manhattan Pharmaceuticals is a publicly-held company. The Company
               was privately-held until the merger. The merger was effected
               pursuant to an Agreement and Plan of Merger dated December 17,
               2002 (the "Merger Agreement") by and among the Company, Manhattan
               Pharmaceuticals and Manhattan Pharmaceuticals Acquisition Corp.
               ("MPAC") which was a wholly-owned subsidiary of Manhattan
               Pharmaceuticals. In accordance with the terms of the Merger
               Agreement, MPAC merged with and into the Company, with the
               Company remaining as the surviving corporation and a wholly-owned
               subsidiary of Manhattan Pharmaceuticals. Pursuant to the Merger
               Agreement, upon the effective time of the merger, the outstanding
               shares of common stock of the Company automatically converted
               into an aggregate of 93,449,584 shares of common stock of
               Manhattan Pharmaceuticals, which represented 80% of the
               outstanding voting stock of Manhattan Pharmaceuticals after
               giving effect to the merger. In addition, immediately prior to
               the merger the Company had outstanding options and warrants to
               purchase an aggregate of 864,280 shares of its common stock,
               which, in accordance with the terms of the merger, automatically
               converted into options and warrants to purchase an aggregate of
               10,984,719 shares of the common stock of Manhattan
               Pharmaceuticals. Since the stockholders of the Company received
               the majority of the voting shares of Manhattan Pharmaceuticals,
               the merger will be accounted for as a reverse acquisition whereby
               the Company will be the accounting acquirer (legal acquiree) and
               Manhattan Pharmaceuticals will be the accounting acquiree (legal
               acquirer) as further explained in Note 10.

               Manhattan Pharmaceuticals is engaged in the business of
               developing and commercializing early-stage technologies,
               particularly biomedical and pharmaceutical technologies. During
               2002, Manhattan Pharmaceuticals had rights to technologies
               relating to three different drug candidates with potential
               application in the areas of cataract, anti-inflammatory and
               anti-microbial treatments. However, management of the combined
               Company intends to initially focus after the merger on the
               development and commercialization of the technologies owned or
               licensed by the Company.


NOTE 2 - LIQUIDITY:
               The Company reported a net loss of $1,037,320 for the year ended
               December 31, 2002. The net loss from August 6, 2001 (date of
               inception) to December 31, 2002 amounted to $1,094,116. As
               discussed in Notes 1 and 10, the Company and Manhattan
               Pharmaceuticals completed their reverse acquisition on February
               21, 2003. Manhattan Pharmaceuticals has also suffered recurring
               losses from its operations. Based on the resources available to
               the Company and Manhattan Pharmaceuticals at December 31, 2002,
               management believes that the combined Company will continue to
               incur net losses through at least December 31, 2003 and will need
               additional equity or debt financing or will need to generate
               revenues through the licensing of its products or by entering



                                      F-8


               into strategic alliances to be able to sustain its operations
               until it can achieve profitability, if ever. These matters raise
               substantial doubt about the Company's ability to continue as a
               going concern.

               The combined Company's ability to continue its operations will
               depend on its ability to raise additional funds through various
               potential sources such as equity and debt financing,
               collaborative agreements and strategic alliances, and its ability
               to realize the full potential of its technology in development.
               Additional funds are currently not available on acceptable terms
               and may not become available. There can be no assurance that any
               additional funding that the combined Company obtains will be
               sufficient to meet the combined Company's needs in the short- and
               long-term. Through December 31, 2002, a significant portion of
               the financing obtained by the Company and Manhattan
               Pharmaceuticals has been through private placements of common
               stock, preferred stock and warrants, the issuance of common stock
               for stock options and warrants exercised and debt financing.
               Until and unless the combined Company's operations generate
               significant revenues, the combined Company will attempt to
               continue to fund operations from cash on hand and through the
               sources of capital previously described. From November 2002
               through February 20, 2003, the combined Company has raised
               $2,747,600 from financing activities.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
             Use of estimates:
                  The preparation of financial statements in conformity with
                  accounting principles generally accepted in the United States
                  of America requires management to make estimates and
                  assumptions that affect certain reported amounts of assets and
                  liabilities and disclosure of contingent assets and
                  liabilities at the date of the financial statements and the
                  reported amounts of expenses during the reporting period.
                  Actual results could differ from those estimates.

               Research and development expenses:
                  Research and development expenses are expensed as incurred.

               Income taxes:
                  The Company accounts for income taxes pursuant to the asset
                  and liability method which requires deferred income tax assets
                  and liabilities to be computed for temporary differences
                  between the financial statement and tax bases of assets and
                  liabilities that will result in taxable or deductible amounts
                  in the future based on enacted tax laws and rates applicable
                  to the periods in which the differences are expected to affect
                  taxable income. Valuation allowances are established when
                  necessary to reduce deferred tax assets to the amount expected
                  to be realized. The income tax provision is the tax payable or
                  refundable for the period plus or minus the change during the
                  period in deferred tax assets and liabilities.

               Stock-based compensation:
                  Options, warrants and stock awards issued to nonemployees and
                  consultants are recorded at their fair value as determined in
                  accordance with Statement of Financial Accounting Standards
                  No. 123, "Accounting for Stock-Based Compensation," and EITF
                  No. 96-18, "Accounting for Equity Instruments That are Issued
                  to Other Than Employees for Acquiring, or in Conjunction with
                  Selling, Goods or Services" and recognized as expense over the
                  related vesting period.


NOTE 4 - NOTE PAYABLE TO BANK:
               At December 31, 2002, the Company had a $600,000 note payable to
               a bank with an annual interest rate of 3.23% due on January 5,
               2003. The note is collateralized by a stockholder's personal
               investment account of $600,000.


                                      F-9



               In January 2003, the Company made a partial repayment of
               principal in the amount of $400,000. The remaining principal
               balance was repaid on March 5, 2003 without any penalty.


NOTE 5 - NOTES PAYABLE TO STOCKHOLDER:
               At December 31, 2002 and 2001, the Company had issued unsecured
               notes payable totaling $206,000 and $27,500, respectively, to a
               stockholder. The notes bear interest at 5% and became due on
               demand when the Company received $1,000,000 from the sale of
               equity securities.


NOTE 6 - DUE AFFILIATE:
               On July 1, 2002, the Company entered into an office services
               agreement (the "Services Agreement") with a company owned by a
               principal stockholder of the Company. Pursuant to the Services
               Agreement, which expires on July 1, 2003, the Company pays
               $15,000 per month for the use of office space and management
               services. For the year ended December 31, 2002, the Company was
               charged $90,000, which is included in selling, general and
               administrative expenses.


NOTE 7 - LICENSE AND CONSULTING AGREEMENTS:
               On February 15, 2002, the Company entered into a License
               Agreement (the "License Agreement") with OED. Under the terms of
               the License Agreement, OED granted to the Company a world-wide
               license to make, use, lease and sell the products incorporating
               the Property (see Note 1). OED also granted to the Company the
               right to sublicense to third parties the Property or aspects of
               the Property with the prior written consent of OED. OED retains
               an irrevocable, nonexclusive, royalty-free right to use the
               Property solely for its internal, noncommercial use. The License
               Agreement shall terminate automatically upon the date of the last
               to expire patent contained in the Property or upon the Company's
               bankruptcy. OED may terminate the License Agreement in the event
               of a material breach by the Company that is not cured within the
               notice period. The Company may terminate the License Agreement
               for any reason upon 60 days notice.

               Under the License Agreement, the Company agreed to pay to OED
               certain licensing fees which are being expensed as they are
               incurred. Through December 31, 2002, the Company paid $175,000 in
               licensing fees which is included in research and development
               expense. In addition, pursuant to the License Agreement, the
               Company issued 1,000,000 shares of its common stock to OED. The
               Company valued these shares at their then estimated fair value of
               $1,000.

               In connection with the License Agreement, the Company has agreed
               to future milestone payments to OED as follows:

                  (i) $250,000 upon the treatment of the first patient in a
                  Phase I clinical trial under a Company-sponsored
                  investigational new drug application ("IND"); (ii) $250,000
                  upon the treatment of the first patient in a Phase II clinical
                  trial under a Company-sponsored IND; (iii) $750,000 upon the
                  first successful completion of a Company-sponsored Phase II
                  clinical trial under a Company-sponsored IND; (iv) $2,000,000
                  upon the first successful completion of a Company-sponsored
                  Phase III clinical trial under a Company sponsored IND; and
                  (v) $6,000,000 upon the first final approval of the first new
                  drug application for the first licensed product by the United
                  States Food and Drug Administration.

               In addition to the License Agreement, the Company entered into a
               consulting agreement with OED. The agreement became effective in
               February 2002, at a fee of $6,250 per month, and will terminate
               when the License Agreement terminates. The fees associated with
               the consulting agreement are expensed as incurred. OED agreed to
               serve as a member of the Company's Scientific Advisory


                                      F-10


               Board and to render consultative and advisory services to the
               Company. Such services include research, development and clinical
               testing of the Company's technology as well as the reporting of
               the findings of such tests, assistance in the filing of patent
               applications and oversight and direction of efforts in regards to
               personnel for clinical development.


NOTE 8 - INCOME TAXES:
               The estimated tax effects of significant temporary differences
               and carryforwards that gave rise to net deferred income tax
               assets as of December 31, 2002 and 2001 are as follows:



                                                2002         2001
                                             ----------    ----------
                                                     
Net deferred tax assets:
   Net operating loss carryforwards          $  417,000    $   22,000
   Research and experimentation credit
       carryforwards                             26,000
   Stock options granted to consultants          24,000
                                             ----------    ----------
                                                467,000        22,000
   Less valuation allowance                    (467,000)      (22,000)
                                             ----------    ----------

Net deferred tax assets                      $       --    $       --
                                             ==========    ==========


               Since realization of the benefits from the temporary differences
               is not considered by management to be more likely than not, a
               full valuation allowance has been provided to reduce deferred tax
               assets to zero. The valuation allowance increased by $445,000 and
               $22,000 during the year ended December 31, 2002 and the period
               from August 6, 2001 (date of inception) to December 31, 2001,
               respectively.

               At December 31, 2002, the Company has net operating loss
               carryforwards of approximately $1,044,000 for Federal and state
               tax purposes which expire through 2022. At December 31, 2002, the
               Company also has research and experimentation credit
               carryforwards of approximately $26,000 for Federal and state tax
               purposes which expire through 2022 for Federal purposes and until
               fully utilized for state purposes.

               For Federal and state tax purposes, the Company's net operating
               loss and tax credit carryforwards may be subject to certain
               limitations on annual utilization attributable to equity
               transactions that result in changes in ownership, as defined by
               the Tax Reform Act of 1986.


NOTE 9 - STOCKHOLDERS' EQUITY (DEFICIENCY):
               The Company issued 4,000,000 shares of common stock to 38
               investors during December 2001 for subscriptions receivable of
               $4,000 or $.001 per share. During 2002, the Company received the
               $4,000.

               In August 2002, the Company entered into one-year agreements with
               four consultants and issued a total of 40,000 options to these
               consultants to purchase 40,000 shares of the Company's common
               stock at an exercise price of $.01 per share expiring in August
               2007. The Company valued these options at $60,589 and is
               amortizing the expense through August 2003. Therefore, the
               Company has expensed $22,721 in 2002 and has deferred $37,868.
               During 2002, no options were exercised.

               During 2002, the Company commenced a private placement and sold
               1,197,250 shares of common stock at $1.60 per share and received
               proceeds of $1,704,318, net of expenses of $211,181. Each


                                      F-11



               investor received warrants equal to 10% of the number of shares
               of common stock purchased and, accordingly, the Company issued
               119,275 warrants in 2002 in connection with the private
               placement. Each warrant has an exercise price of $1.60 per share
               and expires in 2007.

               During January and February 2003, the Company sold an additional
               520,000 shares of common stock at $1.60 per share and 52,000
               warrants through the private placement and received net proceeds
               of approximately $832,000.

               In addition, in connection with the private placement, the
               Company issued to Joseph Stevens & Co., Inc., a NASD-member
               broker-dealer, warrants to purchase 652,555 shares of the
               Company's common stock that are exercisable at $1.60 per share
               and expire in 2008.


NOTE 10- MERGER:
               Pursuant to the Merger Agreement (see Note 1), on February 21,
               2003, the effective time of the merger, the outstanding shares of
               common stock of the Company automatically converted into an
               aggregate of 93,449,584 shares of common stock of Manhattan
               Pharmaceuticals, which represented 80% of the outstanding voting
               stock of Manhattan Pharmaceuticals after giving effect to the
               merger. In addition, immediately prior to the merger the Company
               had outstanding options and warrants to purchase an aggregate of
               864,280 shares of its common stock, which, in accordance with the
               terms of the merger, automatically converted into options and
               warrants to purchase an aggregate of 10,984,719 shares of the
               common stock of Manhattan Pharmaceuticals. Since the stockholders
               of the Company received the majority of the voting shares of
               Manhattan Pharmaceuticals, the merger will be accounted for as a
               reverse acquisition whereby the Company will be the accounting
               acquirer (legal acquiree) and Manhattan Pharmaceuticals will be
               the accounting acquiree (legal acquirer). Based on the five day
               average price of the common stock of Manhattan Pharmaceuticals of
               $0.10 per share as of February 21, 2003, the Company's purchase
               price for the acquisition of Manhattan Pharmaceuticals
               approximates $2,336,000, which represents 20 percent of the
               market value of the combined Company's post-merger total
               outstanding shares of 116,811,980. Based on the preliminary
               information currently available, the Company expects to recognize
               patents and licenses for substantially all of the purchase price.
               Upon completion of formal purchase price allocation there may be
               a decrease in the amount assigned to intangible assets and a
               corresponding increase in in-process research and development.

                     INTRODUCTION TO THE UNAUDITED PRO FORMA
                     CONDENSED COMBINED FINANCIAL STATEMENTS

         On February 21, 2003, Manhattan Pharmaceuticals, Inc. (formerly known
as "Atlantic Technology Ventures, Inc.") (Manhattan Pharmaceuticals or the
"Company") completed a reverse acquisition of privately-held Manhattan Research
Development, Inc., (formerly Manhattan Pharmaceuticals, Inc.) (Manhattan
Research) a Delaware corporation. The merger was effected pursuant to an
Agreement and Plan of Merger dated December 17, 2002 (the "Merger Agreement") by
and among the Company, Manhattan Research and Manhattan Pharmaceuticals
Acquisition Corp, the Company's wholly-owned subsidiary ("MPAC"). In accordance
with the terms of the Merger Agreement, MPAC merged with and into Manhattan
Research, with Manhattan Research remaining as the surviving corporation and a
wholly-owned subsidiary of the Company. Pursuant to the Merger Agreement, upon
the effective time of the merger, the outstanding shares of common stock of
Manhattan Research automatically converted into an aggregate of 93,449,584
shares of the Company's common stock, which represented 80 percent of the
Company's outstanding voting stock after giving effect to the merger. In
addition, immediately prior to the merger Manhattan Research had outstanding
options and warrants to purchase an aggregate of 864,280 shares of its common
stock, which, in accordance with the terms of the merger, automatically
converted into options and warrants to purchase an aggregate of 10,984,719
shares of the Company's common stock. Since the stockholders of Manhattan
Research received the majority of the voting shares of the Company, the merger
is being accounted for as a reverse acquisition whereby Manhattan Research will
be the accounting acquirer (legal acquiree) and the Company will be the
accounting acquiree (legal acquirer). Based on the five day average price of the
Company's common stock of $0.10 per share, the purchase price approximates
$2,336,000, which represents 20 percent of the combined Company's post-merger
total outstanding shares of 116,811,980. In connection with the merger, the
Company changed its name from "Atlantic Technology Ventures, Inc." to "Manhattan
Pharmaceuticals, Inc." Based on the preliminary information currently available,
Manhattan Research expects to recognize patents and licenses for substantially
all of the purchase price. Upon completion of a formal purchase price allocation
there may be a decrease in the amount assigned to intangible assets and a
corresponding increase in in-process research and development.

         The Unaudited Pro Forma Condensed Combined Statement of Operations
combines the historical consolidated statements of operations of the Company and
Manhattan Research giving effect to the merger as if it had been consummated on
January 1, 2002. The Unaudited Pro Forma Condensed Combined Balance Sheet
combines the historical consolidated balance sheet of the Company and the
historical consolidated balance sheet of Manhattan Research, giving effect to
the merger as if it had been consummated on December 31, 2002.

         We present the unaudited pro forma condensed combined financial
information for informational purposes only. The pro forma information is not
necessarily indicative of what our financial position or results of operations
actually would have been had we completed the merger on December 31, 2002 or on
January 1, 2002. In addition, the unaudited pro forma condensed combined
financial information does not purport to project the future financial position
or operating results of the combined company.

         We prepared the unaudited pro forma condensed combined financial
information using the purchase method of accounting with Manhattan Research
treated as the acquirer. Accordingly, Manhattan Research's cost to acquire the
Company will be allocated to the assets acquired and liabilities assumed based
upon their estimated fair values as of the date of acquisition. The allocation
is dependent upon certain valuations and other studies that have not progressed
to a stage where there is sufficient information to make a definitive
allocation. Accordingly, the purchase price allocation pro forma adjustments are
preliminary and have been made solely for the purpose of providing unaudited pro
forma condensed combined financial information.

(1)      DESCRIPTION OF TRANSACTION AND BASIS OF PRESENTATION

         On February 21, 2003, Manhattan Pharmaceuticals, Inc. (formerly known
as "Atlantic Technology Ventures, Inc.") (Manhattan Pharmaceuticals or the
"Company") completed a reverse acquisition of privately-held Manhattan Research
Development, Inc., (formerly Manhattan Pharmaceuticals, Inc.) (Manhattan
Research) a Delaware corporation. The merger was effected pursuant to an
Agreement and Plan of Merger dated December 17, 2002 (the "Merger Agreement") by
and among the Company, Manhattan Research and Manhattan Pharmaceuticals
Acquisition Corp, the Company's wholly-owned subsidiary ("MPAC"). In accordance
with the terms of the Merger Agreement, MPAC merged with and into Manhattan
Research, with Manhattan Research remaining as the surviving corporation and a
wholly-owned subsidiary of the Company. Pursuant to the Merger Agreement, upon
the effective time of the merger, the outstanding shares of common stock of
Manhattan Research automatically converted into an aggregate of 93,449,584
shares of the Company's common stock, which represented 80 percent of the
Company's outstanding voting stock after giving effect to the merger. In
addition, immediately prior to the merger Manhattan Research had outstanding
options and warrants to purchase an aggregate of 864,280 shares of its common
stock, which, in accordance with the terms of the merger, automatically
converted into options and warrants to purchase an aggregate of 10,984,719
shares of the Company's common stock. Since the stockholders of Manhattan
Research received the majority of the voting shares of the Company, the merger
is being accounted for as a reverse acquisition whereby Manhattan Research will
be the accounting acquirer (legal acquiree) and the Company will be the
accounting acquiree (legal acquirer). Based on the five day average price of the
Company's common stock of $0.10 per share, the purchase price approximates
$2,336,000, which represents 20 percent of the combined Company's post-merger
total outstanding shares of 116,811,980. In connection with the merger, the
Company changed its name from "Atlantic Technology Ventures, Inc." to "Manhattan
Pharmaceuticals, Inc." Based on the preliminary information currently available,
Manhattan Research expects to recognize patents and licenses for substantially
all of the purchase price. We recognize that if a final valuation, which is
expected to be completed within three to six months from the completion of the
merger, derives different amounts from our preliminary estimate, we will adjust
the combined condensed financial statements. Upon completion of a formal
purchase price allocation there may be a decrease in the amount assigned to
intangible assets and a corresponding increase in in-process research and
development.

         The merger will be accounted for as a purchase by Manhattan Research
under accounting principles generally accepted in the United States of America.
Under the purchase method of accounting, the assets and liabilities of the
Company will be recorded as of the acquisition date, at their respective fair
values, and combined with those of Manhattan Research. The reported financial
condition and results of operations of Manhattan Research after completion of
the merger will reflect these values, but will not be restated retroactively to
reflect the historical financial position or results of operations of the
Company.

(2)      Pro Forma Adjustments

(a)      To reflect conversion of preferred stock and preferred warrants to
         common stock.

(b)      To reflect issuance of 93,449,584 shares to the common shareholders of
         Manhattan Research and the conversion of the Company's preferred stock
         and preferred warrants and the exchange of certain common stock
         warrants in connection with the merger.

(c)      To eliminate deficit accumulated during development stage of the
         Company.

(d)      To reflect estimated merger expenses.

(e)      To reflect the fair value of property and equipment.

(f)      To eliminate historical paid in capital of the Company and to reflect
         issuance of new common shares in connection with the merger.

(g)      To reflect amortization of intangible assets acquired with an assumed
         useful life of 10 years.
