                        (A Development Stage Enterprise)
             Notes to Consolidated Financial Statements (Unaudited)

(1)        ORGANIZATION ACTIVITIES:

Nature of Business -- Palatin Technologies, Inc. ("Palatin" or the "Company") is
a development stage enterprise dedicated to developing and commercializing
products and technologies for diagnostic imaging and ethical drug development
utilizing peptide, monoclonal antibody and radiopharmaceutical technologies.

Business Risk and Liquidity - The Company's accompanying financial statements
have been prepared in conformity with principles of accounting applicable to a
going concern. These principles contemplate the realization of assets and the
satisfaction of liabilities in the normal course of business.

As shown in the accompanying financial statements, the Company incurred
substantial net losses of $5,154,707 for the six months ended December 31, 1998
and has a deficit accumulated during development stage of $28,474,687. The
Company anticipates incurring additional operating losses over at least the next
several years, and such losses are expected to increase as the Company expands
its research and development activities relating to various technologies. To
achieve profitability, the Company, alone or with others, must successfully
develop and commercialize its technologies and proposed products, conduct
pre-clinical studies and clinical trials, obtain required regulatory approvals
and successfully manufacture and market such technologies and proposed products.
The time required to reach profitability is highly uncertain, and there can be
no assurance that the Company will be able to achieve profitability on a
sustained basis, if at all.

The Company expects that its existing capital resources, including funds
received in February 1999 (see Note 7), will be adequate to fund the Company's
projected operations through May 31, 1999. The Company is actively seeking
additional funds through equity or debt financing, strategic alliances with
corporate partners and others, and through other sources. Based on the Company's
historical ability to raise capital and current market conditions, the Company
believes financing alternatives are available. There can be no assurance the
Company's efforts will be successful. If adequate funds are not available, the
Company may be required to delay, scale back or eliminate certain aspects of its
operations or attempt to obtain funds through arrangements with collaborative
partners or others that may require the Company to relinquish rights to certain
of its technologies, product candidates, products or potential markets. If
adequate funds are not available, the Company's business, financial condition
and results of operations will be materially and adversely affected.

(2)        BASIS OF PRESENTATION:

The accompanying financial statements have been prepared by the Company without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission (the "Commission"). Certain information and footnote disclosures
normally included in the Company's audited annual financial statements have been
condensed or omitted in the Company's interim financial statements. In the
opinion of the Company, these financial statements contain all adjustments
(consisting of only normal recurring adjustments) necessary to present fairly
the financial position of the Company as of December 31, 1998 and June 30, 1998,
and the results of operations for the three and six month periods ended December
31, 1998 and 1997 and for the period from inception (January 28, 1986) to
December 31, 1998 and cash flows for the six months ended December 31, 1998 and
1997, and for the period from inception (January 28, 1986) to December 31, 1998.
The results of operations for the interim period may not necessarily be
indicative of the results of operations expected for the full year, except that
the Company expects to incur a significant loss for the fiscal year ended June
30, 1999.

The accompanying financial statements and the related notes should be read in
conjunction with the Company's audited financial statements for the fiscal years
ended June 30, 1998 and 1997 and the ten months ended June 30, 1996, filed with
the Company's Form 10-KSB for the year ended June 30, 1998.

(3)        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation -- The consolidated financial statements include the
accounts of Palatin and its wholly owned subsidiary, RhoMed Incorporated
("RhoMed"). The remaining subsidiary of Palatin, Interfilm Technologies, Inc.,
is inactive. All significant intercompany accounts and transactions have been
eliminated in consolidation.


                                       6
<PAGE>


Use of Estimates -- The preparation of consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amount of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Cash and Cash Equivalents -- For purposes of presenting cash flows, the Company
considers cash and cash equivalents as amounts on hand, on deposit in financial
institutions and highly liquid investments purchased with an original maturity
of three months or less.

Revenue Recognition -- Grant and contract revenues are recognized as services
are provided. License and royalty revenues are recognized when earned. Product
revenues are recognized upon shipment.

Research and Development Costs -- The costs of research and development
activities are expensed as incurred.

Net Loss per Common Share -- Effective December 31, 1997 the Company adopted
SFAS No. 128, "Earnings per Share" ("SFAS 128"), which supersedes Accounting
Principles Board Opinion No. 15, "Earnings per Share." SFAS 128 requires dual
presentation of basic and diluted earnings per share ("EPS") for complex capital
structures on the face of the statement of operations. Basic EPS is computed by
dividing the income (loss) by the weighted average number of common shares
outstanding for the period. Diluted EPS reflects the potential dilution from the
exercise or conversion of securities into common stock, such as stock options.
For the six months ended December 31, 1998 and 1997 and for the period from
inception (January 28, 1986) through December 31, 1998, there were no dilutive
effects of stock options or warrants as the Company incurred a net loss in each
period. Options and warrants to purchase 2,228,640 shares of common stock at
prices ranging from $0.20 to $360 per share were outstanding at December 31,
1998. In accordance with the provisions of SFAS 128, EPS for prior periods have
been restated.

(4)        COMMITMENTS AND CONTINGENCIES:

Consulting Agreements - The Company is obligated under four consulting
agreements to make payments totaling $200,800 in fiscal 1999.

Legal Proceedings - The Company is subject to various claims and litigation in
the ordinary course of its business. Management believes that the outcome of
such legal proceedings will not have a material adverse effect on the Company.

(5)        STOCKHOLDERS' EQUITY:

On December 31, 1998, the Company sold securities consisting of 287,500 shares
of common stock ("Shares"), with each Share including a detachable five-year
non-redeemable warrant ("Warrants"), through a private placement to accredited
investors for gross proceeds of $1,150,000. Each Warrant entitles the purchaser
to purchase one share of common stock at $4.375. The net proceeds of
approximately $1,000,000 will be used for working capital and the Company's
research and development programs.

(6)        LICENSING FEES  AND ROYALTIES:

The Company recognized $550,000 in license fees as revenue during the quarter
ended December 31, 1998 related to its termination of a license option agreement
with Nihon Medi-Physics ("Nihon"). This $550,000 was previously reported as
deferred license revenue. See Part II, Item 5, Other Information.

(7)        SUBSEQUENT EVENTS:

On February 8, 1999, the Company sold securities consisting of 651,750 Shares,
with each share including a Warrant entitling the purchaser to purchase one
share of common stock at $4.70, through a private placement to accredited
investors for gross proceeds of $2,607,000. The net proceeds of approximately
$2,350,000 will be used for working capital and the Company's research and
development programs

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
           RESULTS OF OPERATIONS.

GENERAL

The following discussion and analysis should be read in conjunction with the
consolidated financial statements and notes thereto filed as part of this Form
10-QSB. Unless otherwise indicated herein, all references to the Company include
Palatin and its wholly owned subsidiary, RhoMed.

Certain statements in this Form 10-QSB contain "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors which may cause the actual results, performance or achievements of
the Company, or industry results, to be materially different from any future
results, performance, or achievements express or implied by such forward-looking
statements. When used in this Form 10-QSB, statements that are not statements of
historical fact may be deemed to be forward-looking statements. Readers are
cautioned not to place undue reliance on these forward-looking statements, which
speak only as of the date of this Form 10-QSB. The Company undertakes no
obligation to publicly release the result of any revisions to these
forward-looking statements that may be made to reflect events or circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

The Company's business is subject to significant risks, including the
uncertainties associated with product development of pharmaceutical products,
problems or delays with clinical trials, failure to receive or delays in
receiving regulatory approval, lack of enforceability of patents and proprietary
rights, manufacturing capacity, industry trends, competition, material costs and
availability, changes in business strategy or development plans, quality of
management, availability of capital, availability of qualified personnel, the
effect of government regulation, the possible effect of Year 2000 issues and
other risks detailed in the Company's filings with the Commission, including the
Company's Form 10-KSB for the year ended June 30, 1998. The Company expects to
incur substantial operating losses over the next several years due to continuing
expenses associated with its research and development programs, including
pre-clinical testing, clinical trials and manufacturing. Operating losses may
also fluctuate from quarter to quarter as a result of differences in the timing
of when expenses are incurred.

RESULTS OF OPERATIONS

Three and Six Month Periods Ended December 31, 1998 Compared to Three and Six
Month Periods Ended December 31, 1997.

Grants and contracts - There was no revenue from grants and contracts during the
three and six month period ended December 31, 1998 and three month period ended
December 31, 1997, compared to $33,967 from grants in the six month period ended
December 31, 1997. The Company recognized $550,000 in license fees as revenue
during the quarter ended December 31, 1998 related to its termination of a
license option agreement with Nihon Medi-Physics. This $550,000 was previously
reported as deferred license revenue. During the six month period ended December
31, 1997, the Company completed its four Phase I grants under the Small Business
Innovative Research program with the National Institutes of Health of the
Department of Health and Human Services.

Sales - There was no revenue from the sale of products during the three and six
month periods ended December 31, 1998 and December 31, 1997. During the fiscal
year ended June 30, 1997, the Company discontinued the manufacture and sale of
RhoChek, the sole product sold by the Company, due to insufficient sales.

Research and development - Research and development expenses increased to
$2,205,272 for the three month period ended December 31, 1998 compared to
$1,474,070 for the three month period ended December 31, 1997, and increased to
$4,342,863 for the six month period ended December 31, 1998 compared to
$2,863,848 for the six month period ended December 31, 1997. The Company
substantially increased research and development spending, primarily relating to
development of the Company's LeuTech(TM) product for diagnostic imaging of
infections, including increased expenses for manufacturing scale-up, consulting
and clinical trials, and also relating to research expenses on the Company's
PT-14(TM) peptide therapeutic product and MIDAS(TM) metallopeptide technology.
The Company expects research and development expenses to continue to increase in
future quarters as the Company expands clinical trials and manufacturing efforts
on the LeuTech product and expands efforts to develop PT-14 and MIDAS
technology.

General and administrative - General and administrative expenses decreased to
$543,174 for the three month period ended December 31, 1998 compared to $799,379
for the three month period ended December 31, 1997 and expenses decreased to
$1,389,464 for the six month period ended December 31, 1998 compared to
$1,479,616 for the six month period ended December 31, 1997. The decrease in

                                       8
<PAGE>

general and administrative expenses were mainly attributable to the continuous
efforts of management to control administrative expenses such as salaries and
out-source consulting fees in addition to the aggressive pursuit of price
negotiations and discounts.

Interest income - Interest income decreased to $25,004 for the three month
period ended December 31, 1998 compared to $122,879 for the three month period
ended December 31, 1997 and interest income decreased to $85,220 for the six
month period ended December 31, 1998 compared to $268,758 for the six month
period ended December 31, 1997. The decrease in interest income is primarily the
result of the depletion of funds available for investment purposes and used to
fund the Company's operations.

Interest expense - Interest expense decreased to $23,601 for the three month
period ended December 31, 1998 compared to $48,656 for the three month period
ended December 31, 1997 and interest expense decreased to $57,600 for the six
month period ended December 31, 1998 compared to $124,179 for the six month
period ended December 31, 1997. The decrease in interest expense is due to the
repayment by the Company of a portion of outstanding principal on long-term debt
provided by Phoenixcor.

Net loss - Net loss increased to $2,197,043 and $5,154,707 for the three and six
month periods ended December 31, 1998 compared to $2,199,226 and $4,164,918 for
the three and six month periods ended December 31, 1997.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company has incurred net operating losses and as of
December 31, 1998, had a deficit accumulated during development stage of
$28,474,687. The Company has financed its net operating losses through December
31, 1998 by a series of debt and equity financings. At December 31, 1998, the
Company had cash and cash equivalents of $2,153,266.

For the six months ended December 31, 1998, the net decrease in cash amounted to
$2,357,921. Cash used for operating activities was $5,008,713, net cash used for
investing activities was $17,101 and cash provided by financing activities was
$2,667,893.

In the six months ended December 31, 1998, the Company completed private
placements totaling 651,136 shares of common stock of the Company, together with
detachable, five-year non-redeemable warrants to purchase an additional 287,500
shares of common stock at $4.375, for gross proceeds of $3,150,000 and net
proceeds of approximately $3,000,000. The net proceeds will be used for working
capital and the Company's research and development of the LeuTech product and an
oral dosage form of PT-14.

On February 8, 1999, the Company sold securities consisting of 651,750 shares of
common stock and detachable, five-year non-redeemable warrants to purchase an
additional 651,750 shares of common stock at $4.70. The Company realized gross
proceeds of $2,607,000 and net proceeds of approximately $2,350,000. The net
proceeds will be used for working capital and the Company's research and
development programs.

On December 29, 1998, the Company and Nihon terminated the existing license
option agreement between them, and entered into a letter of intent relating to
development of diagnostic and therapeutic radiopharmaceutical products based on
the Company's MIDAS peptide technology. The letter provides for certain up-front
payments, together with certain milestone-based payments to be made at later
dates. The Company anticipates entering into a definitive agreement in the first
quarter of 1999. There can be no assurance that the Company and Nihon will ever
enter into a definitive agreement, that additional payments provided for in the
agreement will be made, or that a strategic alliance between the Company and
Nihon will result in the development or commercialization of any product.

The Company's monthly payments on long-term debt payable to Phoenixcor are
$91,695, representing payment of current interest and principal. The final
monthly payment is scheduled to be made in May 1999.

In March 1997, the Company entered into a ten-year lease on research and
development facilities in Edison, New Jersey, which commenced August 1, 1997.
Minimum future lease payments escalate from approximately $116,000 per year to
$200,000 per year after the fifth year of the lease term. The lease will expire
in fiscal year 2007.

Effective August 1, 1997, the Company entered into a five-year lease on
administrative offices in Princeton, New Jersey. Minimum future lease payments
are approximately $97,000 per year.

                                       9
<PAGE>


The Company has entered into three license agreements, which require minimum
yearly payments. Future minimum fiscal year payments under the license
agreements are as follows: 1999 - $150,000, 2000 - $200,000, 2001 - $150,000,
2002 - $200,000 and 2003 - $200,000.

The Company expects to continue actively searching for certain products and
technologies to license or acquire in the future and corporate partnerships,
depending on the financial resources of the Company. If the Company is
successful in identifying a product or technology for acquisition, substantial
funds may be required for such acquisition and subsequent development or
commercialization. There can be no assurance that any acquisition will be
consummated in the future.

The Company has incurred negative cash flows from operations since its
inception, and has expended, and expects to continue to expend in the future,
substantial funds to complete its planned product development efforts. The
Company anticipates incurring additional losses over at least the next several
years, and expects such losses to increase as the Company expands its research
and development activities relating to LeuTech, PT-14 and its MIDAS technology.
The Company's future capital requirements and the adequacy of available funds
depends on numerous factors, including progress in its product development
efforts, the magnitude and scope of such efforts, progress with pre-clinical
studies and clinical trials, progress with regulatory affairs activities, the
cost of filing, prosecution, defending and enforcing patent claims and other
intellectual property rights, competing technological and market developments,
and identifying and consummating suitable strategic alliances. To achieve
profitability, the Company, alone or with others, must successfully develop and
commercialize its technologies and proposed products. The time required to reach
profitability is highly uncertain, and there can be no assurance that the
Company will be able to achieve profitability on a sustained basis, if at all.

The Company expects that its existing capital resources will be adequate to fund
the Company's projected operations through May 31, 1999. The Company is actively
seeking additional funds through equity or debt financing, strategic alliances
with corporate partners and others, or through other sources. Based on the
Company's historical ability to raise capital and current market conditions, the
Company believes financing alternatives are available. There can be no assurance
the Company's efforts will be successful. If adequate funds are not available,
the Company may be required to delay, scale back or eliminate certain aspects of
its operations or attempt to obtain funds through arrangements with
collaborative partners or others that may require the Company to relinquish
rights to certain of its technologies, product candidates, products or potential
markets. If adequate funds are not available, the Company's business, financial
condition and results of operations will be materially and adversely affected.

YEAR 2000 COMPATIBILITY

The year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. In other words,
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in system failures or miscalculations
causing disruptions of operations, including, among others, a temporary
inability to process transactions and information or engage in similar normal
business activities.

The Company is working to resolve the potential impact of the year 2000 on the
ability of the Company's computerized information systems to accurately process
information that may be date-sensitive. The Company is in the process of
conducting a review of all hardware and software throughout the organization.
With this review the Company will be better able to measure the scope of effort
needed to ensure that all departmental operations will continue to function as
of January 1, 2000. With approximately 20 stand-alone personal computers the
Company believes that it does not have significant year 2000 issues related to
its computerized information systems. This review is expected to be completed
during 1999.

In addition, it is also possible that certain computer systems or software
products of the Company's suppliers and contractors may not be year 2000
compatible. Since the Company is not heavily dependent on any particular
software package or vendor in its operations, the Company's assessment of these
year 2000 issues related to its suppliers and contractors is minimal.

The Company currently believes that costs of addressing these issues will not
have a material adverse impact on the Company's financial position and plans to
devote all resources required to resolve any significant year 2000 issues in a
timely manner.

THIS CERTIFIES THAT ________________________ or registered assigns is the
registered holder (the "Registered Holder") of the number of Warrants set forth
above, each of which represents the right to purchase one fully paid and
non-assessable share of Common Stock, par value $0.01 per share (the "Common
Stock"), of Palatin Technologies, Inc., a Delaware corporation (the "Company"),
at the initial exercise price of $4.375 per Warrant (the "Exercise Price") at
any time after the date on which the shares of Common Stock issuable upon
exercise of the Warrants evidenced hereby have been registered under the
Securities Act of 1933, as amended, or such other action as may be required by
federal or state law relating to the issuance or distribution of securities
shall have been taken, and prior to the Expiration Date (as hereinafter
defined), by surrendering this Warrant Certificate, with the Form of Election to
Purchase duly executed at the principal office of the Company and by paying in
full the Exercise Price, plus transfer taxes, if any. Payment of the Exercise
Price shall be made in United States currency, by certified check or money order
payable to the order of the Company. Unless otherwise defined herein, the
capitalized terms used herein shall have the meaning assigned to such terms in
the Purchase Agreement.

        The Warrants have been issued pursuant to a private placement of Common
Stock and Warrants.


                                        1

<PAGE>



        This Warrant Certificate is issued under and in accordance with the
Purchase Agreement dated as of December 31, 1998, between the Company and the
Registered Holder, as amended and is subject to the terms and provisions
contained in said Purchase Agreement. The Registration Rights Agreement between
the Company and the Registered Holder governs the registration rights of the
shares of Common Stock underlying the Warrants.


                              EXERCISE OF WARRANTS

        Issuance of Common Stock. As soon as practicable after the date of
exercise of any Warrants, the Company shall issue, or cause the transfer agent
for the Common Stock, if any, to issue a certificate or certificates for the
number of full shares of Common Stock to which such Registered Holder is
entitled, registered in accordance with the instructions set forth in the Form
of Election to Purchase. All shares of Common Stock issued upon the exercise of
any Warrants shall be validly authorized and issued, fully paid and
non-assessable, and free from all taxes, liens and charges created by the
Company in respect of the issue thereof. Each person in whose name any such
certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of record of the Common Stock represented
thereby on the date of exercise of the Warrants resulting in the issuance of
such shares, irrespective of the date of issuance or delivery of such
certificate for shares of Common Stock.

        Certificates for Unexercised Warrants. In the event that less than all
of the Warrants represented by a Warrant Certificate are exercised, the Company
shall execute and mail, by first-class mail, within 30 days of the date of
exercise, to the Registered Holder of such Warrant Certificate, or such other
person as shall be designated in the Form of Election to Purchase, a new Warrant
Certificate representing the number of full Warrants not exercised. In no event
shall a fraction of a Warrant be exercised, and the Company shall distribute no
Warrant Certificates representing fractions of Warrants. Final fractions of
shares shall be treated as provided for herein.

        Reservation of Shares. The Company shall at all times reserve and keep
available for issuance upon the exercise of Warrants a number of its authorized
but unissued shares of Common Stock that will be sufficient to permit the
exercise in full of all outstanding Warrants.


                        ADJUSTMENTS AND NOTICE PROVISIONS

        Adjustment of Exercise Price. Subject to the provisions hereof, the
Exercise Price in effect from time to time shall be subject to adjustment, as
follows:


                                        2

<PAGE>



        (a) In case the Company shall at any time after the date hereof (i)
declare a dividend on the outstanding Common Stock payable in shares of its
capital stock, (ii) subdivide the outstanding Common Stock, (iii) combine the
outstanding Common Stock into a smaller number of shares, or (iv) issue any
shares of its capital stock by reclassification of the Common Stock (including
any such reclassification in connection with a consolidation or merger in which
the Company is the continuing corporation), then, in each case, the Exercise
Price, and the number of shares of Common Stock issuable upon exercise of the
Warrants in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination, or reclassification, shall be
proportionately adjusted so that the Holders of the Warrants after such time
shall be entitled to receive the aggregate number and kind of shares which, if
such Warrants had been exercised immediately prior to such time, such Registered
Holders would have owned upon such exercise and been entitled to receive by
virtue of such dividend, subdivision, combination or reclassification. Such
adjustment shall be made successively whenever any event listed above shall
occur.

        (b) In case the Company shall issue or fix a record date for the
issuance to all holders of Common Stock of rights, options, or warrants to
subscribe for or purchase Common Stock (or securities convertible into or
exchangeable for Common Stock) at a price per share (or having a conversion or
exchange price per share, if a security convertible into or exchangeable for
Common Stock) less than the Current Market Price per share of Common Stock (as
determined below) on such record date, then, in each case, the Exercise Price
shall be adjusted by multiplying the Exercise Price in effect immediately prior
to such record date by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding on such record date plus the number of shares
of Common Stock which the aggregate offering price of the total number of shares
of Common Stock so to be offered (or the aggregate initial conversion or
exchange price of the convertible or exchangeable securities so to be offered)
would purchase at such Current Market Price and the denominator of which shall
be the number of shares of Common Stock outstanding on such record date plus the
number of additional shares of Common Stock to be offered for subscription or
purchase (or into which the convertible or exchangeable securities so to be
offered are initially convertible or exchangeable). Such adjustment shall become
effective at the close of business on such record date; provided, however, that,
to the extent the shares of Common Stock (or securities convertible into or
exchangeable for shares of Common Stock) are not delivered, the Exercise Price
shall be readjusted after the expiration of such rights, options, or warrants
(but only with respect to Warrants exercised after such expiration), to the
Exercise Price which would then be in effect had the adjustments made upon the
issuance of such rights, options, or warrants been made upon the basis of
delivery of only the number of shares of Common Stock (or securities convertible
into or exchangeable for shares of Common Stock) actually issued.
Notwithstanding anything to the contrary contained herein, no adjustment shall
be made to the Exercise Price until any condition to the vesting of such rights,
options or warrants shall be fulfilled or satisfied (and then only with respect
to the portion thereof which shall have vested). In case any subscription price
may be paid in a consideration part or all of

                                        3

<PAGE>



which shall be in a form other than cash, the value of such consideration shall
be as determined in good faith by the board of directors of the Company, whose
determination shall be conclusive absent manifest error. Shares of Common Stock
owned by or held for the account of the Company or any majority-owned subsidiary
shall not be deemed outstanding for the purpose of any such computation.

        (c) In case the Company shall distribute to all holders of Common Stock
(including any such distribution made to the stockholders of the Company in
connection with a consolidation or merger in which the Company is the continuing
corporation) evidences of its indebtedness, cash (other than any cash dividend
which, together with any cash dividends paid within the twelve (12) months prior
to the record date for such distribution, does not exceed 5% of the Current
Market Price at the record date for such distribution) or assets (other than
distributions and dividends payable in shares of Common Stock), or rights,
options, or warrants to subscribe for or purchase Common Stock, or securities
convertible into or exchangeable for shares of Common Stock (excluding those
with respect to the issuance of which an adjustment of the Exercise Price is
provided pursuant to the foregoing paragraph), then, in each case, the Exercise
Price shall be adjusted by multiplying the Exercise Price in effect immediately
prior to the record date for the determination of stockholders entitled to
receive such distribution by a fraction, the numerator of which shall be the
Current Market Price per share of Common Stock on such record date, less the
fair market value (as determined in good faith by the board of directors of the
Company, whose determination shall be conclusive absent manifest error) of the
portion of the evidences of indebtedness or assets so to be distributed, or of
such rights, options, or warrants or convertible or exchangeable securities, or
the amount of such cash, applicable to one share, and the denominator of which
shall be such Current Market Price per share of Common Stock. Such adjustment
shall become effective at the close of business on such record date.

        Current Market Price. For the purpose of any computation under this
Warrant, the Current Market Price per share of Common Stock on any date shall be
deemed to be the average of the daily closing prices for the fifteen (15)
consecutive trading days immediately preceding the date in question. The closing
price for each day shall be (a) the last reported sales price regular way or, in
case no such reported sale takes place on such day, the closing bid price
regular way, in either case on the principal national securities exchange or
market system (including, for purposes hereof, the NASDAQ National Market System
or the NASDAQ SmallCap) on which the Common Stock, is listed or admitted to
trading, (b) if the Common Stock, is not listed or admitted to trading on any
national securities exchange or market system, the highest reported bid price
for the Common Stock, as furnished by the National Association of Securities
Dealers, Inc. through NASDAQ or a similar organization if NASDAQ is no longer
reporting such information, or (c) if on any such date the Common Stock is not
listed or admitted to trading on any national securities exchange and is not
quoted by NASDAQ National Market System or NASDAQ SmallCap System or any similar
organization, as determined by reference to the "pink sheets" published by the
National Quotation Bureau or, if not so published, by such

                                        4

other method of determining the market value of a share of Common Stock, as the
board of directors of the Company shall in good faith from time to time deem to
be fair, whose determination shall be conclusive absent manifest error shall be
used.

        No Adjustments to Exercise Price. No adjustment in the Exercise Price
shall be required if such adjustment is less than $.05; provided, however, that
any adjustments which by reason of this Warrant are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Warrant shall be made to the nearest cent or to the
nearest one thousandth of a share, as the case may be.

        Deferral of Adjustments to Exercise Price. In any case in which this
Warrant shall require that an adjustment in the Exercise Price be made effective
as of a record date for a specified event, the Company may elect to defer, until
the occurrence of such event, issuing to the Registered Holders of the Warrants,
if any Registered Holder has exercised a Warrant after such record date, the
shares of Common Stock, if any, issuable upon such exercise over and above the
shares of Common Stock, if any, issuable upon such exercise on the basis of the
Exercise Price in effect prior to such adjustment; provided, however, that the
Company shall deliver to such exercising Registered Holder a due bill or other
appropriate instrument evidencing such Registered Holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

        Adjustment to Number of Shares. Upon each adjustment of the Exercise
Price as a result of the calculations made above the Warrants shall thereafter
evidence the right to purchase, at the adjusted Exercise Price, that number of
shares (calculated to the nearest thousandth) obtained by dividing (A) the
product obtained by multiplying the number of shares purchasable upon exercise
of the Warrants prior to adjustment of the number of shares by the Exercise
Price in effect prior to adjustment of the Exercise Price by (B) the Exercise
Price in effect after such adjustment of the Exercise Price.

        Reorganization. In case of any capital reorganization, other than in the
cases referred to above, or the consolidation or merger of the Company with or
into another corporation (other than a merger or consolidation in which the
Company is the continuing corporation and which does not result in any
reclassification of the outstanding shares of Common Stock or the conversion of
such outstanding shares of Common Stock into shares of other stock or other
securities or property), or the sale of the property of the Company as an
entirety or substantially as an entirety (collectively such actions being
hereinafter referred to as "Reorganizations"), there shall thereafter be
deliverable upon exercise of any Warrant (in lieu of the number of shares of
Common Stock theretofore deliverable) the number of shares of stock or other
securities or property to which a Registered Holder of the number of shares of
Common Stock which would otherwise have been deliverable upon the exercise of
such Warrant would have been entitled upon such Reorganization if such Warrant
had been exercised in full immediately prior to such Reorganization. In case of
any Reorganization, appropriate adjustment, as determined in good faith by the
Board of Directors of the Company, shall be made in the application of the
provisions herein set

                                        5

<PAGE>



forth with respect to the rights and interests of Registered Holders so that the
provisions set forth herein shall thereafter be applicable, as nearly as
practicable, in relation to any shares or other property thereafter deliverable
upon exercise of Warrants. The Company shall not effect any such Reorganization,
unless upon or prior to the consummation thereof the successor corporation, or
if the Company shall be the surviving corporation in any such Reorganization and
is not the issuer of the shares of stock or other securities or property to be
delivered to holders of shares of the Common Stock outstanding at the effective
time thereof, then such issuer, shall assume by written instrument the
obligation to deliver to the Registered Holder of any Warrant Certificate such
shares of stock, securities, cash or other property as such holder shall be
entitled to purchase in accordance with the foregoing provisions.
Notwithstanding anything to the contrary contained herein, in the event of sale
or conveyance or other transfer of all or substantially all of the assets of the
Company as a part of a plan for liquidation of the Company, all rights to
exercise any Warrant shall terminate thirty (30) days after the Company gives
written notice to each Registered Holder of a Warrant Certificate that such sale
or conveyance of other transfer has been consummated.

        Reclassifications. (a) In case of any reclassification or change of the
shares of Common Stock issuable upon exercise of the Warrants (other than a
change in par value or from no par value to a specified par value, or as a
result of a subdivision or combination, but including any change in the shares
into two or more classes or series of shares), the Registered Holders of the
Warrants shall have the right thereafter to receive upon exercise of the
Warrants solely the kind and amount of shares of stock and other securities,
property, cash, or any combination thereof receivable upon such reclassification
or change by a Registered Holder of the number of shares of Common Stock for
which the Warrants might have been exercised immediately prior to such
reclassification or change. Thereafter, appropriate provision shall be as nearly
equivalent as practicable to the adjustments in this Warrant. The above
provisions of this paragraph shall similarly apply to successive
reclassifications and changes of shares of Common Stock.

        (b) Notwithstanding anything to the contrary herein contained, in the
event of a transaction contemplated by the prior paragraph in which the
surviving, continuing, successor, or purchasing corporation demands that all
outstanding Warrants be extinguished prior to the closing date of the
contemplated transaction, the Company shall give prior notice (the "Merger
Notice") thereof to the Registered Holders advising them of such transaction.
The Registered Holders shall have ten (10) days after the date of the Merger
Notice to elect to (i) exercise the Warrants in the manner provided herein or
(ii) receive from the surviving, continuing, successor, or purchasing
corporation, with respect to outstanding Warrants, the same consideration
receivable by a Registered Holder of the number of shares of Common Stock for
which the Warrants might have been exercised immediately prior to such
consolidation, merger, sale, or purchase reduced by such amount of the
consideration as has a market value equal to the exercise price of the Warrants,
as determined by the Board of Directors of the Company, whose determination
shall be conclusive absent manifest error. If any Registered Holder fails to
timely notify the

                                        6

<PAGE>



Company of its election, the Holder shall be deemed for all purposes to have
elected the option set forth in (ii) above. Any amounts receivable by a Holder
who has elected the option set forth in (ii) above shall be payable at the same
time as amounts payable to stockholders in connection with any such transaction.

        Verification of Computations. Whenever the Exercise Price is adjusted as
provided in this Warrant, the Company will promptly obtain a certificate of the
chief financial officer of the Company setting forth the Exercise Price as so
adjusted and a brief statement of the facts accounting for such adjustment, and
will make available a brief summary thereof to the Registered Holders of the
Warrant Certificates, at their addresses listed on the register maintained for
the purpose by the Company.

        Exercise Price Not Less Than Par Value. In no event shall the Exercise
Price be adjusted below the par value per share of the Common Stock.

        Notice of Certain Actions. In case at any time the Company shall 
propose:

               (a) to pay any dividend or make any distribution on shares of
        Common Stock in shares of Common Stock or make any other distribution
        (other than regularly scheduled cash dividends which are not in a
        greater amount per share than the most recent such cash dividend) to all
        holders of Common Stock; or

               (b) to issue any rights, warrants, or other securities to all
        holders of Common Stock entitling them to purchase any additional shares
        of Common Stock or any other rights, warrants, or other securities; or

               (c) to effect any reclassification or change of outstanding
        shares of Common Stock, or any consolidation, merger, sale, lease, or
        conveyance of property, described above; or

               (d) to effect any liquidation, dissolution, or winding-up of the
        Company;

then, in each such case, the Company shall cause notice of such proposed action
to be mailed to each Registered Holder of a Warrant Certificate. Such notice
shall be mailed, at least ten (10) days prior to the record date for determining
holders of the Common Stock for purposes of receiving such payment or offer or
at least ten (10) days prior to the earlier of the date upon which such action
is to take place or any record date to determine holders of Common Stock
entitled to receive such securities or other property, as the case may be.

        Notice of Adjustments. Whenever any adjustment is made pursuant to this
Warrant, the Company shall cause notice of such adjustment to be mailed to each
Registered Holder of a Warrant Certificate within fifteen (15) days thereafter,
such notice to include in reasonable detail (i) the events precipitating the
adjustment, (ii) the

                                        7

<PAGE>



computation of any adjustments, and (iii) the Exercise Price, the number of
shares or the securities or other property purchasable upon exercise of each
Warrant after giving effect to such adjustment.

        Warrant Certificate Amendments. Irrespective of any adjustments pursuant
to this Warrant, Warrant Certificates theretofore or thereafter issued need not
be amended or replaced, but certificates thereafter issued shall bear an
appropriate legend or other notice of any adjustments.

        Fractional Shares. The Company shall not be required upon the exercise
of any Warrant to issue fractional shares of Common Stock which may result from
adjustments in accordance with this Warrant to the Exercise Price or number of
shares of Common Stock purchasable under each Warrant. If more than one Warrant
is exercised at one time by the same Registered Holder, the number of full
shares of Common Stock which shall be deliverable shall be computed based on the
number of shares deliverable in exchange for the aggregate number of Warrants
exercised. With respect to any final fraction of a share called for upon the
exercise of any Warrant or Warrants, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the same fraction of the
Current Market Price of a share of Common Stock calculated in accordance with
this Warrant.

        Adjustments Not Provided For. If any change to the capitalization of the
Company should occur with respect to which a favorable adjustment to the rights
and interests of the Registered Holders of the Warrants should be made, and such
adjustment is not otherwise provided for in this Warrant, such appropriate
adjustment should be made as determined in good faith by the Board of Directors
of the Company.

        No Warrant may be exercised after 5:00 P.M., New York City time, on the
expiration date (the "Expiration Date") which will be December 31, 2003.  All
Warrants evidenced hereby shall thereafter become void.


                          OTHER PROVISIONS RELATING TO
                          RIGHTS OF REGISTERED HOLDERS
                             OF WARRANT CERTIFICATES

        Rights of Warrant Holders. No Warrant Certificate shall entitle the
registered holder thereof to any of the rights of a stockholder of the Company,
including, without limitation, the right to vote, to receive dividends and other
distributions, to receive any notice of, or to attend, meetings of stockholders
or any other proceedings of the Company.

        Lost, Stolen, Mutilated or Destroyed Warrant Certificates.  If any 
Warrant Certificate shall be mutilated, lost, stolen or destroyed, the Company
in its discretion may execute and deliver, in exchange and substitution for and
upon cancellation of a mutilated

                                        8

<PAGE>



Warrant Certificate, or in lieu of or in substitution for a lost, stolen or
destroyed Warrant Certificate, a new Warrant Certificate for the number of
Warrants represented by the Warrant Certificate so mutilated, lost, stolen or
destroyed but only upon receipt of evidence of such loss, theft or destruction
of such Warrant Certificate, and of the ownership thereof, and indemnity, if
requested, all satisfactory to the Company. Applicants for such substitute
Warrant Certificates shall also comply with such other reasonable regulations
and pay such other reasonable charges incidental thereto as the Company may
prescribe. Any such new Warrant Certificate shall constitute an original
contractual obligation of the Company, whether or not the allegedly lost,
stolen, mutilated or destroyed Warrant Certificate shall be at any time
enforceable by anyone.


                   SPLIT UP, COMBINATION, EXCHANGE, TRANSFER,
                    AND CANCELLATION OF WARRANT CERTIFICATES

        Split Up, Combination, Exchange and Transfer of Warrant Certificates.
Prior to the latest time at which the Warrants may be exercised, subject to any
applicable laws, rules or regulations restricting transferability, Warrant
Certificates, subject to the provisions hereof, may be split up, combined or
exchanged for other Warrant Certificates representing a like aggregate number of
Warrants or may be transferred in whole or in part. Any holder desiring to split
up, combine or exchange a Warrant Certificate or Warrant Certificates shall make
such request in writing delivered to the Company at its principal office and
shall surrender the Warrant Certificate or Warrant Certificates so to be split
up, combined or exchanged at said office with the Form of Assignment. Upon any
such surrender for split up, combination, exchange or transfer, the Company
shall execute and deliver to the person entitled thereto a Warrant Certificate
or Warrant Certificates, as the case may be, as so requested in the Form of
Assignment. The Company may require the holder to pay a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any split
up, combination, exchange or transfer of Warrant Certificates prior to the
issuance of any new Warrant Certificate.

        Cancellation of Warrant Certificates. Any Warrant Certificate
surrendered upon the exercise of Warrants or for split up, combination, exchange
or transfer, or purchased or otherwise acquired by the Company, shall be
canceled and shall not be reissued by the Company; and, except as otherwise
provided herein in case of the exercise of less than all of the Warrants
evidenced by a Warrant Certificate or in case of a split up, combination,
exchange or transfer, no Warrant Certificate shall be issued hereunder in lieu
of such canceled Warrant Certificate. Any Warrant Certificate so canceled shall
be destroyed by the Company.

        Agreement of Warrant Certificate Holders. Every holder of a Warrant
Certificate by accepting the same consents and agrees with the Company and with
every other holder of a Warrant Certificate that:


                                        9

<PAGE>



               (a) transfer of the Warrant Certificates shall be registered on
        the books of the Company only if surrendered at the principal office of
        the Company, duly endorsed or accompanied by a proper instrument of
        transfer; and

               (b) prior to due presentment for registration of transfer, the
        Company may deem and treat the person in whose name the Warrant
        Certificate is registered as the absolute owner thereof and of the
        Warrants evidenced thereby (notwithstanding any notations of ownership
        or writing on the Warrant Certificates made by anyone other than the
        Company) for all purposes whatsoever, and the Company shall not be
        affected by any notice to the contrary.


                                  OTHER MATTERS

        Governing Law.  The laws of the State of New York shall govern this
Warrant Certificate.


        IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed.

                               PURCHASE AGREEMENT

           This Purchase Agreement (the "Agreement") is made as of _______, 1998
by and between Palatin Technologies, Inc., a Delaware corporation (the
"Company"), with its principal office at 214 Carnegie Center, Suite 100,
Princeton, New Jersey 08540, and each of the purchasers who are signatories
hereto and any other purchasers who are made a party to this Agreement pursuant
to Section 1 (individually, a "Purchaser" and collectively, the "Purchasers").

                                    RECITALS

           The Company is hereby offering (the "Offering") a minimum of
$3,000,000 and a maximum of $7,000,000 (a) shares (the "Shares") of the
Company's Common Stock, $.01 par value per share (the "Common Stock") and (b)
warrants (the "Warrants") to purchase one share of Common Stock of the Company.
The Shares and the Warrants offered in the Offering shall sometimes collectively
be referred to herein as the "Securities." The Securities will be sold by the
Company to Purchasers pursuant to Regulation D ("Regulation D") promulgated
under the Securities Act of 1933, as amended (the "Act").

           The purchase price of the Shares to be offered in the Offering (the
"Offering Price") will be determined based upon the average reported closing
sales prices for the Common Stock on The Nasdaq SmallCap Market SM for the last
five (5) business days immediately prior to the Initial Closing Date (as defined
below). Every one share of Common Stock purchased in the Offering will entitle
the Purchaser to a Warrant to purchase one share of Common Stock at an exercise
price per share equal to the Offering Price, subject to certain adjustments. The
Warrants will be issued pursuant to a warrant agreement (the "Warrant
Agreement") between the Company and American Stock Transfer & Trust Company.

           Each prospective purchaser has received and carefully read a copy of
a private placement memorandum, dated October 2, 1998, as amended (the
"Placement Memorandum"), describing the Company's business, financial and
operating condition, the Offering and information regarding risks to be
evaluated when contemplating an investment in the Company through the Offering.

                     3.3       Investment Representations.

                               3.3.1      Purchaser is acquiring the Securities

to or for resale in connection with any distribution or public offering thereof
within the meaning of the Act, except pursuant to an effective registration

                               A) THE SECURITIES REPRESENTED HEREBY HAVE NOT
           BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
           "ACT"), OR UNDER THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES
           ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT
           BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND THE
           APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
           EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN
           OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER
           TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE
           WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

                              3.3.3      The  Purchaser has been furnished with
and has carefully read the Placement Memorandum (including, without limitation,
all appendices and supplements thereto, and is familiar with and understands the
terms of the Offering, including the rights to which the Purchaser is entitled
under the Registration Rights Agreement and the Warrant Agreement). The
Purchaser has been furnished with and has carefully read the Company's Quarterly
Report on Form 10-QSB for the Quarter ended September 30, 1998 (the "10-Q"). In
evaluating the suitability of an investment in the Company, the Purchaser has
not relied upon any representation or other information (whether oral or
written) from the Company, or any agent, employee or affiliate of the Company
other than as set forth in the Placement Memorandum or the 10-Q and the results
of Purchaser's own independent investigation. With respect to individual or
partnership tax and other economic considerations involved in this investment,
the Purchaser has carefully considered and has, to the extent the Purchaser
believes such discussion necessary, discussed with the Purchaser's professional
legal, tax, accounting and financial advisers the suitability of an investment
in the Securities for the Purchaser's particular tax and financial situation and

                                       4
<PAGE>

has determined that the Securities being subscribed for by the Purchaser are a
suitable investment for the Purchaser.

                              3.3.4      The Purchaser acknowledges that (i) the
Purchaser has had the right to request copies of any documents, records and
books pertaining to this investment and (ii) such documents, records, and books
pertaining to this investment which the Purchaser requested (including, without
limitation, the Placement Memorandum) have been made available for inspection by
the Purchaser, the Purchaser's representative, attorney, accountant or
adviser(s) (the "Purchaser's advisers").

                              3.3.5       The Purchaser and/or the Purchaser's
adviser(s) has/have had a reasonable opportunity to ask questions of and receive
answers from a person or persons acting on behalf of the Company concerning the
Offering and all such questions have been answered to the full satisfaction of
the Purchaser.

                              3.3.6       The  Purchaser is not subscribing for
Securities as a result of or subsequent to any advertisement, article, notice or
other communication published in any newspaper, magazine or similar media or
broadcast over television or radio or presented at any seminar or meeting.

                              3.3.7       Purchaser is an "accredited investor"
as such term is defined in Rule 501 under the Act and as indicated by the
Purchaser's responses to the Confidential Purchaser Questionnaire.

                              3.3.8       Purchaser is a resident of, and all 
communications regarding Purchaser's purchase of the Securities were sent to
Purchaser, in the state of Purchaser's residence shown on the subscription page
attached hereto.

                              3.3.9       If the Purchaser is a natural person,
the Purchaser has reached the age of majority in the state or other jurisdiction
in which the Purchaser resides, has adequate means of providing for the
Purchaser's current financial needs and contingencies, is able to bear the
substantial economic risks of an investment in the Securities for an indefinite
period of time, has no need for liquidity in such investment and, at the present
time, could afford a complete loss of such investment.

                              3.3.10      The Purchaser or the Purchaser's
representative, as the case may be, has such knowledge and experience in
financial, tax and business matters so as to enable the Purchaser to utilize the
information made available to the Purchaser in connection with the Offering to
evaluate the merits and risks of an investment in the Securities and to make an
informed investment decision with respect thereto.

                              3.3.11      The Purchaser recognizes that an 
investment in the Securities involves substantial risks, including loss of the
entire amount of such investment. Further, the Purchaser has carefully read and
considered the matters set forth under the caption "Risk Factors" in the
Placement Memorandum, and has taken full cognizance of and understands all of
the risks related to the purchase of the Securities.

Offering from any party other than the Company.

and hold harmless the Company and each officer, director or control person of
the Company, who is or may be a party or is or may be threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, by reason of or
arising from any actual or alleged misrepresentation or misstatement of facts or
omission to represent or state facts made or alleged to have been made by the
Purchaser to the Company, or omitted or alleged to have been omitted by the
Purchaser, concerning the Purchaser or the Purchaser's authority to invest or
financial position in connection with the Offering, including, without
limitation, any such misrepresentation, misstatement or omission contained in
any investor qualification questionnaire or any other document submitted by the
Purchaser, against losses, liabilities and expenses for which the Company, or
any officer, director or control person of the Company has not otherwise been
reimbursed (including attorneys' fees, judgments, fines and amounts paid in
settlement) actually and reasonably incurred by the Company, or such officer,
director or control person in connection with such action, suit or proceeding.

recommendation or endorsement of the Securities.

                     5.4      The Offering is intended to be exempt from 
registration under the Securities Act by virtue of Section 4(2) of the

                     5.5      There can be no assurance  that the Purchaser will
be able to sell or dispose of the Securities. It is understood that in order not
to jeopardize the Offering's exempt status under Section 4(2) of the Securities

RECOMMENDED BY ANY FEDERAL OR STATE SECURITIES COMMISSION OR REGULATORY
AUTHORITY. FURTHERMORE, THE FOREGOING AUTHORITIES HAVE NOT CONFIRMED THE
ACCURACY OR DETERMINED THE ADEQUACY OF THE PLACEMENT MEMORANDUM OR THIS PURCHASE
AGREEMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                     5.10     THE SECURITIES ARE SUBJECT TO RESTRICTIONS ON

          6. DEFAULTING PROSPECTIVE PURCHASERS. (a) If, on the relevant Closing
Date, a prospective Purchaser defaults in the performance of its obligations
under this Agreement, a non-defaulting prospective Purchaser may make
arrangements for the purchase of the Securities that would have been purchased
by such defaulting prospective Purchaser by other persons satisfactory to the
Company and the non-defaulting prospective Purchasers, but if no such
arrangements are made within 36 hours after such default, this Agreement shall
terminate without liability on the part of the non-defaulting prospective
Purchasers or the Company except that prospective Purchasers will continue to be
liable for the payment of expenses to the extent set forth in Section 7.8 and
except that the provisions of Section 3.5 shall not terminate and shall remain
in effect.

<PAGE>

                     (b)      Nothing contained herein shall relieve a 
defaulting prospective Purchaser of any liability it may have for damages caused
by its default. If other purchasers agree to purchase the Securities of a
defaulting prospective Purchaser, either the non-defaulting prospective
Purchaser or the Company may postpone a Closing Date for up to seven (7) full
business days in order to effect any changes that in the reasonable opinion of
counsel for the Company or counsel for the Placement Agent may be necessary in
the Placement Memorandum, the Operative Documents or in any other document or
arrangement, and the Company agrees to prepare and distribute promptly any
amendment or supplement to the Placement Memorandum that effects any such
changes.

          8.         ESCROW AGENT.  To induce Graham & James LLP to serve as the

hereto that:

                     (a)       The escrow agent shall not be under any duty to
give the property held by it hereunder (the "Escrowed Property") any greater
degree of care than it gives its own similar property.

                     (b)       This Section 8 of this  Agreement expressly sets
forth all the duties of the escrow agent with respect to any and all matters
pertinent hereto. No implied duties or obligations shall be read into this
Agreement against the escrow agent. The escrow agent shall not be bound by the
provisions of any agreement among the other parties hereto except this Section 8
of this Agreement.

                     (c)       The escrow agent shall not be liable, except for
its own gross negligence or willful misconduct and, except with respect to
claims based upon such gross negligence or willful misconduct that are
successfully asserted against the escrow agent, the other parties hereto shall
jointly and severally indemnify and hold harmless the escrow agent from and
against any and all losses, liabilities, claims, actions, damages and expenses,

                                       10
<PAGE>

including, without limitation, reasonable attorneys' fees and disbursements,
arising out of or in connection with this Agreement.

                     (d)       The escrow agent shall be entitled to rely upon
any order, judgment, certification, demand, notice, instrument or other writing
delivered to it hereunder without being required to determine the authenticity
or the correctness of any fact stated therein or the propriety or validity of
the service thereof. The escrow agent may act in reliance upon any instrument or
signature believed by it to be genuine and may assume that any person purporting
to give receipt or advice or make any statement or execute any document in
connection with the provisions hereof has been duly authorized to do so.

                     (e)       The escrow agent may act pursuant to the advice
of counsel with respect to any matter relating to this Agreement and shall not
be liable for any action taken or omitted in accordance with such advice.

                     (f)       The escrow agent does not have any interest in
the Escrowed Property deposited hereunder but is serving as escrow holder only
and having only possession thereof. The other parties shall, on a joint and
several basis, pay or reimburse the escrow agent upon request for any and all
expenses, if any, incurred by the escrow agent in connection with this Agreement
and transfer taxes or other taxes relating to the Escrowed Property incurred in
connection herewith and shall indemnify and hold harmless the escrow agent from
any amounts that it is obligated to pay in the way of such expenses and taxes.
This subparagraph and subparagraph (c) shall survive notwithstanding any
termination of this Agreement or the resignation of the escrow agent.

                     (g)       The escrow agent makes no representation as to 
the validity, value, genuineness or the collectability of any security or other
document or instrument held by or delivered to it.

                     (h)       The escrow agent may at any time resign as suc
by delivering the Escrowed Property to any successor escrow agent jointly
designated by the other parties hereto in writing, or to any court of competent
jurisdiction, whereupon the escrow agent shall be discharged of and from any and
all further obligations arising in connection with this Agreement. The
resignation of the escrow agent will take effect on the earlier of (a) the
appointment of a successor (including a court of competent jurisdiction) or (b)
the day which is 30 days after the date of delivery of its written notice of
resignation to the other parties hereto. If at that time the escrow agent has
not received a designation of a successor escrow agent, the escrow agent's sole
responsibility after that time shall be to safekeep the Escrowed Property until
receipt of a designation of successor escrow agent or a joint written
disposition instruction by the other parties hereto or a final order of a court
of competent jurisdiction.

                     (i)       In the event of any disagreement between the 
other parties hereto resulting in adverse claims or demands being made in
connection with the Escrowed Property, or in the event that the escrow agent in
good faith is in doubt as to what action it should take hereunder, the escrow
agent shall be entitled to retain the Escrowed Property until the escrow agent
shall have received (i) a final non-appealable order of a court of competent
jurisdiction directing delivery of the Escrowed Property or (ii) a written

                                       11
<PAGE>

agreement executed by the other parties hereto directing delivery of the
Escrowed Property, in which event the escrow agent shall disburse the Escrowed
Property in accordance with such order or agreement. Any court order shall be
accompanied by a legal opinion by counsel for the presenting party satisfactory
to the escrow agent to the effect that said opinion is final and non-appealable.

                     (j)       Notwithstanding anything to the contrary 
contained herein, the escrow agent's duties and obligations hereunder shall
terminate upon the release and distribution of the Escrowed Property in
accordance with the terms of this Agreement.

                     (k)       Each of the  Company and the  Purchaser  
understands and agrees that, notwithstanding its duties as escrow agent
hereunder, the escrow agent is the attorney for the Company, and, accordingly,
neither any services as escrow agent hereunder nor any provisions hereof, either
express or implied, shall restrict or inhibit the escrow agent in any way from
representing the Company or its affiliates in any action, dispute, controversy,
arbitration, suit or negotiation arising under this Agreement or under any other
agreement or in any manner or context whatsoever, whether or not directly or
indirectly involving the Company or its affiliates.


          9.         EXECUTION OF AGREEMENT.

                        the Shares and the Warrant Shares.

                (b)     The Company  shall use its best efforts to maintain with
                        the   Commission  a   Registration   Statement  that  is
                        effective  and causes the Shares and the Warrant  Shares

        2.3     Piggyback Registration

                (a)     Until the time set forth in Section 2.3(g) hereof,  each
                        time that the  Company  proposes  to  Register  a public
                        offering of its Common Stock, other than (i) pursuant to
                        a  Registration  Statement  on Form  S-4 or Form  S-8 or
                        similar  or  successor  forms or (ii) on a  Registration
                        Statement  filed in connection with an exchange offer or
                        other offer of Common Stock solely to the  then-existing
                        stockholders of the Company,  the Company shall promptly
                        give written notice of such proposed Registration to all
                        holders of Shares and Warrant Shares,  which shall offer
                        such  holders  the  right to  request  inclusion  of any
                        Registrable Securities in the proposed Registration.

                (b)     Each holder of Shares or Warrant  Shares  shall have ten
                        (10) days or such longer period as shall be set forth in
                        the notice from the receipt of such notice to deliver to
                        the Company a written  request  specifying the number of
                        shares of Registrable  Securities such holder intends to
                        sell and the holder's intended plan of disposition.

                (c)     The Company shall have the exclusive right to select all
                        underwriters  for any  underwritten  public  offering of
                        securities  of the  Company,  including  all  Shares and
                        Warrant   Shares.   In  the  event  that  the   proposed
                        Registration  by the Company is, in whole or in part, an
                        underwritten   public  offering  of  securities  of  the
                        Company,  any request under Section 2.3(b) shall contain
                        the holder's  agreement that the Registrable  Securities
                        will be included in the  underwriting  on the same terms
                        and  conditions as the shares of Common  Stock,  if any,
                        otherwise  being sold  through  underwriters  under such
                        Registration.

                (d)     Upon  receipt of a written  request  pursuant to Section
                        2.3(b),  the Company shall promptly use its best efforts
                        to  cause  all  such   Registrable   Securities   to  be

                                      -3-
<PAGE>

                        Registered,  to the extent  required  to permit  sale or
                        disposition as set forth in the written request.

                (e)     Notwithstanding   the   foregoing,   if   the   managing
                        underwriter   of   an   underwritten   public   offering
                        determines  and advises in writing that the inclusion of
                        all  Registrable  Securities  proposed to be included in
                        the  underwritten  public  offering,  together  with any
                        shares  proposed  to be sold by the  Company for its own
                        account and any other issued and  outstanding  shares of
                        Common Stock proposed to be included  therein by holders
                        other than the holders of Registrable  Securities  (such
                        other holders' shares hereinafter  collectively referred
                        to as the  "Other  Shares"),  would  interfere  with the
                        successful  marketing of the  securities  proposed to be
                        included in the underwritten public offering,  including
                        the price at which such securities can be sold, then the
                        number of such shares of persons  other than the Company
                        that  otherwise  would be included in such  underwritten
                        public offering shall be excluded from such underwritten
                        public  offering in a number  deemed  necessary  by such
                        managing underwriter,  first by excluding, to the extent
                        necessary,  other  shares  held by persons  who have not
                        exercised  contractual  rights to include such Shares in
                        the offering pursuant to the Prior  Registration  Rights
                        Agreements (as  hereinafter  defined),  and then, to the
                        extent necessary,  by excluding  Registrable  Securities
                        participating in such underwritten public offering,  pro
                        rata,  based on the  number  of  shares  of  Registrable
                        Securities each holder  proposes to include;  and, then,
                        excluding to the extent necessary, other Shares proposed
                        to be included  by the holders of other  Shares who have
                        exercised  registration  rights  granted  to them  under
                        registration  rights agreements of the Company in effect
                        on the date hereof or any other  registration  rights in
                        effect  on the date  hereof  (collectively,  the  "Prior
                        Registration Rights Agreements").

                (f)     All Shares and Warrant  Shares that are not  included in
                        an underwritten  public offering pursuant to Section 2.3
                        shall be withheld from the market by the holders thereof
                        for a period, not to exceed 12 months following a public
                        offering,   that  the  managing  underwriter  reasonably
                        determines   is   necessary   in  order  to  effect  the
                        underwritten public offering. The holders of such Shares
                        and the Warrant Shares shall execute such  documentation
                        as  the  managing  underwriter  reasonably  requests  to
                        evidence this lock-up.

                (g)     The registration rights provided by this Agreement shall
                        expire with respect to any Registrable Security upon the
                        earliest  to  occur  of  (i)  the   effectiveness  of  a
                        Registration Statement that includes in the Registration
                        effected   thereby,   at  the   request   of  a  Selling

                                      -4-
<PAGE>

                        Stockholder, such Registrable Security; (ii) the date on
                        which such  Registrable  Security is eligible for resale
                        under Rule 144 without regard to the volume  limitations
                        thereof; and (iii) five years from the date hereof.

        2.4     Preparation and Filing.  If and whenever the Company is under an
                obligation  pursuant to the  provisions of this Section 2 to use
                its best efforts to effect the  Registration  of any Registrable
                Securities, the Company shall, as expeditiously as practicable:

                (a)     prepare  and file  with the  Commission  a  Registration
                        Statement with respect to such  Registrable  Securities,
                        using such form of available  Registration  Statement as
                        is reasonably  selected by the Company (unless otherwise
                        specified  herein),  and use its best  efforts  to cause
                        such   Registration   Statement  to  become  and  remain
                        effective,  keeping each Selling  Stockholder advised as
                        to  the  initiation,  progress  and  completion  of  the
                        Registration;

                (b)     prepare and file with the Commission such amendments and
                        supplements  to  such  Registration  Statements  and the
                        prospectus  used  in  connection  therewith  as  may  be
                        necessary to keep such Registration  Statement effective
                        for,  in  the  case  of a  Required  Registration  under
                        Section 2.2, the period set forth in Section 2.2(b) and,
                        in the case of a Piggyback  Registration  under  Section
                        2.3, six months,  and to comply with the  provisions  of
                        the  Securities  Act with  respect  to the sale or other
                        disposition  of all  Registrable  Securities  covered by
                        such Registration Statement;

                (c)     furnish  to each  Selling  Stockholder  such  number  of
                        copies of any summary  prospectus  or other  prospectus,
                        including a preliminary  prospectus  and all  amendments
                        and   supplements   thereto,   in  conformity  with  the
                        requirements  of the  Securities  Act,  and  such  other
                        documents as such  Selling  Stockholder  may  reasonably
                        request in order to facilitate  the public sale or other
                        disposition of such  Registrable  Securities;  provided,
                        however,  that no such prospectus need be furnished more
                        than,  in the  case  of a  Required  Registration  under
                        Section  2.2,  six months  after the  conclusion  of the
                        period set forth in Section 2.2(b) and, in the case of a
                        Piggyback  Registration  under  Section  2.3, six months
                        after the effective date of the  Registration  Statement
                        related thereto;

                (d)     use  its  best   efforts  to  register  or  qualify  the
                        Registrable  Securities  covered  by  such  Registration
                        Statement  under the securities or blue sky laws of such
                        jurisdictions   as  each   Selling   Stockholder   shall
                        reasonably  request  and do any  and all  other  acts or

                                      -5-
<PAGE>

                        things which may be reasonably necessary or advisable to
                        enable  such  holder to  consummate  the public  sale or
                        other   disposition  in  such   jurisdictions   of  such
                        Registrable  Securities;  provided,  however,  that  the
                        Company  shall not be  required  to  consent  to general
                        service of process,  qualify to do business as a foreign
                        corporation where it would not be otherwise  required to
                        qualify or submit to liability  for state or local taxes
                        where it is not liable  for such  taxes or  provide  any
                        undertaking  or make any  change in its  Certificate  of
                        Incorporation; and

                (e)     at  any  time  when  a   prospectus   covered   by  such
                        Registration Statement is required to be delivered under
                        the  Securities  Act  within  the   appropriate   period
                        mentioned in Section 2.2(b) or Section 2.3(b) hereof, as
                        the case may be, notify each Selling  Stockholder of the
                        happening  of  any  event  as  a  result  of  which  the
                        prospectus included in such Registration  Statement,  as
                        then  in  effect,  includes  an  untrue  statement  of a
                        material fact or omits to state a material fact required
                        to be stated therein or necessary to make the statements
                        therein not misleading in the light of the circumstances
                        then  existing  and,  at the  request  of  such  seller,
                        prepare,  file and furnish to such  seller a  reasonable
                        number of copies of a  supplement  to or an amendment of
                        such   prospectus  as  may  be  necessary  so  that,  as
                        thereafter  delivered to the  purchasers of such shares,
                        such prospectus shall not include an untrue statement of
                        a  material  fact  or  omit to  state  a  material  fact
                        required to be stated  therein or  necessary to make the
                        statement  therein  not  misleading  in the light of the
                        circumstances  then  existing.  The  Company  may  delay
                        amending or supplementing the prospectus for a period of
                        up  to 90  days  if  the  Company  is  then  engaged  in
                        negotiations  regarding a material  transaction that has
                        not   been   publicly   disclosed,   and   the   Selling
                        Stockholders shall suspend their sale of Shares until an
                        appropriate  supplement or prospectus has been forwarded
                        to them or the proposed transaction is abandoned.

        Notwithstanding the foregoing, with respect to the proposed Registration
        of Registrable  Securities  pursuant to Section 2.3 hereof,  the Company
        may  withdraw or cease  proceeding  with any  proposed  Registration  of
        Registrable Securities if it has withdrawn or ceased proceeding with the
        proposed  Registration  of Common  Stock of the  Company  with which the
        Registration of such Registrable Securities was to be included.

        2.5     Expenses.  The  Company  shall  pay  all  Registration  Expenses
                incurred by the Company in complying with this Section 2.

        2.6     Information  Furnished  by  Purchaser.  It shall be a  condition
                precedent to the Company's  obligations  under this Agreement as
                to any Selling Stockholder that each Selling Stockholder furnish

                                      -6-

                to the  Company  in  writing  such  information  regarding  such
                Selling  Stockholder  and  the  distribution  proposed  by  such
                Selling Stockholder as the Company may reasonably request.

        2.7     Indemnification.

                2.7.1   Company's  Indemnification  of  Purchasers.  The Company
                        shall  indemnify each Selling  Stockholder,  each of its
                        officers,  directors and constituent partners,  and each
                        person controlling (within the meaning of the Securities
                        Act)  such  Selling  Stockholder,  against  all  claims,
                        losses,  damages or  liabilities  (or actions in respect
                        thereof)  suffered or  incurred  by any of them,  to the
                        extent such claims, losses, damages or liabilities arise
                        out  of or are  based  upon  any  untrue  statement  (or
                        alleged  untrue  statement) of a material fact contained
                        in any prospectus or any related Registration  Statement
                        incident to any such  Registration,  or any omission (or
                        alleged  omission)  to state  therein  a  material  fact
                        required to be stated  therein or  necessary to make the
                        statements  therein not misleading,  or any violation by
                        the Company of any rule or regulation  promulgated under
                        the   Securities  Act  applicable  to  the  Company  and
                        relating to actions or inaction  required of the Company
                        in  connection  with  any  such  Registration;  and  the
                        Company will  reimburse  each such Selling  Stockholder,
                        each of its officers, directors and constituent partners
                        and  each   person  who   controls   any  such   Selling
                        Stockholder,  for any reasonable,  documented  legal and

                        or defending any such claim, loss, damage,  liability or
                        action; provided,  however, that the indemnity contained
                        in this Section 2.7.1 shall not apply to amounts paid in
                        settlement of any such claim, loss, damage, liability or
                        action if settlement is effected  without the consent of
                        the Company  (which  consent shall not  unreasonably  be
                        withheld); and provided,  further, that the Company will
                        not be liable in any such  case to the  extent  that any
                        such claim,  loss,  damage,  liability or expense arises
                        out of or is based upon any untrue (or  alleged  untrue)
                        statement  or omission  based upon  written  information
                        furnished  to the Company by such  Selling  Stockholder,
                        underwriter,  controlling  person  or other  indemnified
                        person and stated to be for use in  connection  with the
                        offering of securities of the Company.

                2.7.2   Selling  Stockholder's  Indemnification of Company. Each
                        Selling Stockholder shall indemnify the Company, each of
                        its directors and officers, each underwriter, if any, of
                        the  Company's  securities  covered  by  a  Registration

                        person  controlling  such  other  Selling   Stockholder,
                        against all claims,  losses, damages and liabilities (or
                        actions in respect thereof)  suffered or incurred by any
                        of them  and  arising  out of or based  upon any  untrue
                        statement  (or alleged  untrue  statement) of a material
                        fact contained in such Registration Statement or related
                        prospectus,  or any  omission  (or alleged  omission) to
                        state  therein a  material  fact  required  to be stated
                        therein or necessary to make the statements  therein not
                        misleading, or any violation by such Selling Stockholder
                        of  any  rule  or  regulation   promulgated   under  the
                        Securities  Act  applicable to such Selling  Stockholder
                        and  relating  to actions or  inaction  required of such
                        Selling  Stockholder in connection with the Registration
                        of  the   Registrable   Securities   pursuant   to  such
                        Registration Statement;  and will reimburse the Company,
                        such  other  Selling   Stockholders,   such   directors,
                        officers,    partners,    persons,    underwriters   and
                        controlling persons for any reasonable, documented legal
                        and  other   expenses   incurred  in   connection   with
                        investigating or defending any such claim, loss, damage,
                        liability  or  action;  provided,   however,  that  such
                        indemnification   and  reimbursement  shall  be  to  the
                        extent,  but  only  to  the  extent,  that  such  untrue
                        statement (or alleged untrue  statement) or omission (or
                        alleged omission) is made in such Registration Statement
                        or prospectus  in reliance  upon and in conformity  with
                        written  information  furnished  to the  Company by such
                        Selling   Stockholder  and  stated  to  be  for  use  in
                        connection with the offering of Registrable Securities.

                2.7.3   Indemnification Procedure.  Promptly after receipt by an
                        indemnified  party  under this  Section 2.7 of notice of
                        the  commencement of any action which may give rise to a
                        claim for  indemnification  hereunder,  such indemnified
                        party will, if a claim in respect  thereof is to be made
                        against an  indemnifying  party under this  Section 2.7,
                        notify  the   indemnifying   party  in  writing  of  the
                        commencement   thereof  and  generally   summarize  such
                        action.  The indemnifying  party shall have the right to
                        participate  in and to assume the defense of such claim,
                        and shall be entitled to select  counsel for the defense
                        of such claim with the approval of any parties  entitled
                        to   indemnification,   which   approval  shall  not  be
                        unreasonably  withheld.  Notwithstanding  the foregoing,
                        the parties entitled to  indemnification  shall have the
                        right   to   employ   separate    counsel    (reasonably
                        satisfactory to the  indemnifying  party) to participate
                        in the  defense  thereof,  but the fees and  expenses of
                        such  separate  counsel  shall be at the expense of such
                        indemnified  parties  unless  the named  parties to such
                        action  or  proceedings  include  both the  indemnifying
                        party and the indemnified  parties and the  indemnifying
                        party  or  such  indemnified  parties  shall  have  been

                                      -8-
<PAGE>

                        advised  by  counsel  that  there are one or more  legal
                        defenses available to the indemnified  parties which are
                        different  from or additional to those  available to the
                        indemnifying  party (in which case,  if the  indemnified
                        parties  notify the  indemnifying  party in writing that
                        they elect to employ separate  counsel at the reasonable
                        expense  of the  indemnifying  party,  the  indemnifying
                        party  shall not have the right to assume the defense of
                        such action or proceeding  on behalf of the  indemnified
                        parties,   it  being  understood,   however,   that  the
                        indemnifying  party  shall not, in  connection  with any
                        such action or proceeding  or separate or  substantially
                        similar  or  related  action or  proceeding  in the same
                        jurisdiction arising out of the same general allegations
                        or   circumstances,   be  liable  for  the   reasonable,
                        documented  fees and  expenses of more than one separate
                        counsel at any time for all indemnified  parties,  which
                        counsel shall be designated in writing by the Purchasers
                        of a majority of the Registrable Securities).

                2.7.4   Contribution.  If the  indemnification  provided  for in
                        this   Section  2.7  from  an   indemnifying   party  is
                        unavailable to an indemnified party hereunder in respect
                        to any losses, claims, damages,  liabilities or expenses
                        referred to herein, then the indemnifying party, in lieu
                        of indemnifying such indemnified party, shall contribute
                        to the amount paid or payable by such indemnified  party
                        as a result of such losses, claims, damages, liabilities
                        or  expenses in such  proportion  as is  appropriate  to
                        reflect the relative fault of the indemnifying party and
                        indemnified  party in connection  with the statements or
                        omissions which result in such losses, claims,  damages,
                        liabilities  or expenses,  as well as any other relevant
                        equitable  considerations.  The  relative  fault of such
                        indemnifying   party  and  indemnified  party  shall  be
                        determined by reference to, among other things,  whether
                        the untrue or  alleged  untrue  statement  of a material
                        fact or the  omission  or  alleged  omission  to state a
                        material  fact relates to  information  supplied by such
                        indemnifying party or indemnified party and the parties'
                        relative  intent,   knowledge,   access  to  information
                        supplied by such indemnifying party or indemnified party
                        and  opportunity to correct or prevent such statement or
                        omission.  The  amount  paid or  payable by a party as a
                        result of the losses, claims,  damages,  liabilities and
                        expenses  referred  to above  shall be deemed to include
                        any   documented   legal  or  other  fees  or   expenses
                        reasonably  incurred  by such party in  connection  with
                        investigating or defending any action, suit,  proceeding
                        or  claim,   or  in   collecting   such   indemnity   or
                        reimbursement from the indemnifying party.

3. Covenants of the Company.

        The Company agrees to:

        (a)     Notify  the  holders of  Registrable  Securities  included  in a
                Registration  Statement (i) of the issuance by the Commission of
                any stop order suspending the effectiveness of such Registration
                Statement  and  (ii)  upon  learning  of the  initiation  of any
                proceedings  for the purpose of suspending  such  effectiveness,
                the existence of such  proceedings.  The Company will make every
                reasonable effort to prevent the issuance of any stop order and,
                if any stop order is issued,  to obtain the  lifting  thereof at
                the earliest possible time.

        (b)     If the  Common  Stock is then  listed on a  national  securities
                exchange,   use  its  best  efforts  to  cause  the  Registrable
                Securities to be listed on such exchange. If the Common Stock is
                not then listed on a national securities exchange,  use its best
                efforts  to  facilitate   the   reporting  of  the   Registrable
                Securities on Nasdaq.

        (c)     Take all other  reasonable  actions  necessary  to expedite  and
                facilitate  disposition  of the  Registrable  Securities  by the
                holders thereof pursuant to the Registration Statement.

        (d)     With a view to making  available  to the holders of  Registrable
                Securities  the  benefits  of Rule  144  promulgated  under  the
                Securities   Act  and  any  other  rule  or  regulation  of  the
                Commission  that may at any time permit the  Purchasers  to sell
                securities  of the Company to the public  without  registration,
                the Company agrees to:

                (i)     make and keep adequate  current public  information with
                        respect to the  Company  available,  as those  terms are
                        understood  and  defined in Rule 144, at all times after
                        90  days   after  the   effective   date  of  the  first
                        Registration  Statement  filed  by the  Company  for the
                        offering of its securities to the general public;

                (ii)    file with the  Commission in a timely manner all reports
                        and other  documents  required of the Company  under the
                        Securities Act and the  Securities  Exchange Act of 1934
                        (the "1934 Act"); and

                (iii)   furnish to each holder of Shares, so long as such holder
                        of  Shares  owns  any  Shares,  forthwith  upon  written
                        request  (a) a written  statement  by the  Company as to
                        whether it has complied with the reporting  requirements
                        of Rule 144, the  Securities Act and the 1934 Act, (b) a
                        copy of the most recent  annual or  quarterly  report of

                                      -10-

                        the Company  and such other  reports  and  documents  so
                        filed by the Company and (c) such other  information  as
                        may be reasonably requested and as is publicly available
                        in  availing  the  holders  of  Shares  of any  rule  or
                        regulation of the  Commission  which permits the selling
                        of any such securities without registration.

        (e)     Prior to the filing of a Registration Statement or any amendment
                thereto (whether pre-effective or post-effective),  and prior to
                the filing of any  prospectus or prospectus  supplement  related
                thereto,  the Company will provide each Selling Stockholder with
                copies  of all  pages  thereto,  if any,  which  reference  such
                Selling Stockholder.

        (f)     If  the  Registration   Statement  relates  to  an  underwritten
                offering,  enter  into  and  perform  its  obligations  under an
                underwriting  agreement, in usual and customary form, including,
                without limitation,  customary  indemnification and contribution
                obligations, with the underwriter's representative.

        (g)     Make  generally  available  to its  security  holders as soon as
                practicable,  but not later  than forty five (45) days after the
                close of the period  covered  thereby,  the Company's  financial
                statements as filed with the Commission.

        (h)     At the request of the  Investors who hold a majority in interest
                of  the  Registrable  Securities  being  sold,  furnish  to  the
                underwriters,  if any, on the date that  Registrable  Securities
                are delivered to the  underwriters for sale in connection with a
                registration  pursuant to this  Agreement (i) an opinion,  dated
                such date,  of the  counsel  representing  the  Company  for the
                purposes  of such  registration,  in form  and  substance  as is
                customarily  given to  underwriters  in an  underwritten  public
                offering,  addressed  to the  underwriters,  and (ii) a  letter,
                dated  such  date,   from  the  independent   certified   public
                accountants  of  the  Company,  in  form  and  substance  as  is
                customarily given by independent certified public accountants to
                underwriters in an underwritten  public  offering,  addressed to

 4.   Miscellaneous.

        (a)     This Agreement shall be governed by and construed under the laws
                of the State of New York.

        (b)     This Agreement may not be assigned by a Purchaser  other than to
                the   purchaser  or   transferee  of  more  than  5,000  of  the
                Purchaser's  Shares,  which  purchaser or transferee  shall be a
                permitted  assign  hereunder  and under the Purchase  Agreement.
                Except as otherwise  expressly  provided herein,  the provisions
                hereof shall inure to the benefit of, and be binding  upon,  the
                successors,    permitted   assigns,    heirs,    executors   and
                administrators of the parties hereto.

        (c)     This Agreement and the other documents delivered pursuant hereto
                constitute the full and entire understanding and agreement among
                the  parties  with  regard to the  subjects  hereof and no party
                shall be liable or bound to any other party in any manner by any
                representations,  warranties,  covenants or agreements except as
                specifically  set  forth  herein  or  therein.  Nothing  in this
                Agreement,  express or  implied,  is intended to confer upon any
                party,  other  than the  parties  hereto  and  their  respective
                successors  and  permitted   assigns,   any  rights,   remedies,
                obligations,   or  liabilities   under  or  by  reason  of  this
                Agreement, except as expressly provided herein.

        (d)     In the  event  that any  provision  of this  Agreement  shall be
                invalid,  illegal  or  unenforceable,  it shall,  to the  extent
                practicable,  be  modified  so as to make it  valid,  legal  and
                enforceable and to retain as nearly as practicable the intent of
                the parties,  and the validity  legality,  and enforceability of
                the  remaining  provisions  shall not in any way be  affected or
                impaired  thereby.  To the extent  permitted by law, the parties
                waive the  benefit  of any  provision  of law that  renders  any
                provision  of the  Agreement  invalid  or  unenforceable  in any
                respect.

        (e)     Except as otherwise  provided herein, any term of this Agreement
                may be amended, and the observance of any term of this Agreement
                may be waived  (either  generally or in a  particular  instance,
                either   retroactively  or  prospectively,   and  either  for  a
                specified  period  of time or  indefinitely),  with the  written
                consent of the Company and the Purchaser.

                                      -12-

        (f)     All  notices  and other  communications  required  or  permitted
                hereunder  shall be in writing  and shall be deemed  effectively
                given  upon  personal  delivery,   on  the  first  business  day
                following  mailing  by  overnight  courier,  or on the fifth day
                following  mailing  by  registered  or  certified  mail,  return
                receipt requested,  postage prepaid, addressed to the Company at
                its address as set forth in the  Purchase  Agreement  and to the
                Purchaser at its address as shown on the books of the Company.

        (g)     The titles of the paragraphs and subparagraphs of this Agreement
                are  for  convenience  of  reference  only  and  are  not  to be
                considered in construing this Agreement.

        (h)     This  Agreement  may be executed in any number of  counterparts,
                each of which  shall be  deemed  an  original,  but all of which
                together shall constitute one instrument.

        (i)     No  waiver  by any  party to this  Agreement  of any one or more
                defaults by any other party or parties in the performance of any
                of the  provisions  hereof  shall  operate or be  construed as a
                waiver of any future  default or defaults,  whether of a like or
                different  nature.  Except  as  expressly  provided  herein,  no
                failure  or  delay on the part of any  party in  exercising  any
                right,  power or  remedy  hereunder  shall  operate  as a waiver
                thereof,  nor shall any single or partial  exercise  of any such
                right,  power or remedy  preclude any other or further  exercise
                thereof or the exercise of any other right, power or remedy.
