                       AMENDMENT NO. 1 TO RIGHTS AGREEMENT

         Amendment No. 1 to Rights Agreement (the "Amendment"), made as of
August 16, 2004, by and among Vion Pharmaceuticals, Inc. a Delaware corporation
(the "Company"), and American Stock Transfer & Trust Company (the "Rights
Agent"). Reference is made herein to that certain Rights Agreement, dated as of
October 26, 1998, by and between the Company and the Rights Agent (the "Rights
Agreement"). Capitalized terms not herein defined shall have the meaning
ascribed thereto in the Rights Agreement.

         WHEREAS, the Rights Agreement may be amended by the parties pursuant to
Section 27; and

         WHEREAS, the Company and the Rights Agent wish to amend the Rights
Agreement;

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the parties hereby agree as follows:

         1. Amendment to Section 11(a)(iii). Section 11(a)(iii) of the Rights
Agreement is hereby amended and restated in its entirety to read as follows:

              (iii) In the event that the number of shares of Common Stock
         which are authorized by the Company's certificate of incorporation but
         not outstanding or reserved for issuance for purposes other than upon
         exercise of the Rights are not sufficient to permit the exercise in
         full of the Rights in accordance with the foregoing subparagraph (ii),
         the Company shall: (A) determine the excess of (1) the value of the
         shares of Common Stock issuable upon the exercise of a Right (the
         "Current Value") over (2) the Purchase Price (such excess, the
         "Spread"), and (B) with respect to each Right, make adequate provision
         to substitute for the shares of Common Stock so issuable, upon payment
         of the applicable Purchase Price, (1) cash, (2) a reduction in the
         Purchase Price, (3) other equity securities of the Company (including,
         without limitation, shares, or units of shares, of preferred stock)
         which the Board of Directors of the Company has deemed to have the
         same economic value as shares of Common Stock (such shares of
         preferred stock, "common stock equivalents"), (4) debt securities of
         the Company, (5) other assets, or (6) any combination of the
         foregoing, having an aggregate value equal to the Current Value, where
         such aggregate value has been determined by the Board of Directors of
         the Company based upon the advice of a nationally recognized
         investment banking firm selected by the Board of Directors of the
         Company; provided, however, if the Company shall not have made
         adequate provision to deliver value pursuant to clause (B) above
         within 30 days following the later of (x) the first occurrence of an
         event described in Section 11(a)(ii) and (y) the date on which the
         Company's right of redemption pursuant to Section 23 expires, then the
         Company shall be obligated to deliver, upon the surrender for exercise
         of a Right and without requiring payment of the Purchase Price, shares
         of Common Stock (to the extent available) and then, if necessary,

                                       1

<PAGE>

         cash, which in the aggregate are equal to the Spread. If the Board of
         Directors of the Company shall determine in good faith that it is
         likely that sufficient additional shares of Common Stock could be
         authorized for issuance upon exercise in full of the Rights, the 30
         day period set forth above may be extended to the extent necessary,
         but not more than 120 days following the first occurrence of an event
         described in Section 11(a)(ii), in order that the Company may seek
         stockholder approval for the authorization of such additional shares
         (such period as it may be extended, the "Substitution Period"). To the
         extent that the Company determines that some action need be taken
         pursuant to the first and/or second sentences of this Section
         11(a)(iii), the Company (x) shall provide, that such action shall
         apply uniformly to all outstanding Rights, and (y) may suspend the
         exercisability of the Rights until the expiration of the Substitution
         Period in order to seek any authorization of additional shares and/or
         to decide the appropriate form of distribution to be made pursuant to
         such first sentence and to determine the value thereof. In the event
         of any such suspension, the Company shall issue a public announcement
         stating that the exercisability of the Rights has been temporarily
         suspended, as well as a public announcement at such time as the
         suspension is no longer in effect. For purposes of this Section
         11(a)(iii), the value of the Common Stock shall be the current market
         price (as determined pursuant to Section 11(d)) per share of the
         Common Stock on the date of the first occurrence of an event referred
         to in Section 11(a)(ii) and the value of any "common stock equivalent"
         shall be deemed to have the same value as the Common Stock on such
         date.

         2. Rights Agreement Otherwise Unamended. The terms of the Rights
Agreement not amended hereby shall, except as the context unambiguously
requires, remain in full force and effect.

         3. Entire Agreement. This Amendment, together with the provisions of
the Rights Agreement not amended hereby, constitute the entire agreement between
the parties hereto with respect to the subject matter hereof and supersede all
other prior agreements, whether written or oral, between the parties hereto.

         4. Counterparts. This Amendment may be executed in one or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same document.

                                       2

         IN WITNESS WHEREOF, each of the parties hereto has caused this
Amendment to be executed in its respective corporate name by one of its duly
authorized officers, all as of the date first above written.

                                                                   May ___, 2004

Spencer Trask Ventures, Inc.
535 Madison Avenue
18th Floor
New York, New York 10022

Ladies and Gentlemen:

Home Director, Inc., a Delaware corporation (the "Company"), hereby confirms its
agreement (the "Agreement") with Spencer Trask Ventures, Inc., a Delaware
corporation (the "Placement Agent"), as follows (unless the context otherwise
requires, as used herein, the "Company" refers to Home Director, Inc. and each
of its subsidiaries, if any):

1. Offering.

(a) The Company will offer (the "Offering") for sale through the Placement Agent
as exclusive agent for the Company, investment units ("Units"), each Unit
comprised of (i) one (1) share (the "Shares") of common stock, par value $0.01
per share, of the Company (the "Common Stock") and (ii) a three (3)-year warrant
(the "Warrant", together with the Shares, the "Securities") to purchase one
share of Common Stock. The offering price per Unit (the "Purchase Price per
Unit") shall be equal to the lesser of (i) eighty percent (80%) of the average
of the closing bid prices of the Common Stock on the OTC Bulletin Board over the
ten (10) trading days immediately prior to each closing of the sale of Units (a
"Closing") or (ii) with respect to Closings after the first Closing, the lowest
Purchase Price per Unit at a prior Closing. If the Purchase Price per Unit at
any Closing is lower than any prior Closing, the Purchase Price per Unit for all
such prior Closings will be adjusted to such lower price. The exercise price of
each Warrant shall be equal to 125% of the Purchase Price per Unit at the
applicable Closing. The total amount of gross proceeds from the sale of Units in
the Offering shall be a minimum of $1.5 million (the "Minimum Amount") and a
maximum of $4.0 million (the "Maximum Amount"). In addition, for the purpose of
covering overallotments in the sale of the Units, the Company and the Placement
Agent may agree to sell additional Units with total gross proceeds equal to up
to thirty percent (30%) of the Maximum Amount. All share prices, exercise prices
and conversion prices should be assumed to be proportionally adjusted to reflect
stock splits, stock dividends, recapitalizations and the like. The Minimum and
Maximum Amounts include $1,015,000 of convertible notes which will be converted
into Units at the first Closing.

(b) The Units will be offered on a reasonable efforts basis for a period of 90
days from the date of the Memorandum (as defined in Section 1(d)) (the
"Commencement Date"), which period may be extended by the Placement Agent and
the Company for up to an additional 60 days (the

"Offering Period"). The date on which the Offering shall terminate shall be
referred to as the "Termination Date."

(c) The minimum subscription for Units shall be $50,000, however, the Placement
Agent and the Company may, in their discretion, agree to accept less than the
minimum subscription amount; provided, however, that the Placement Agent shall
not tender to the Company and the Company shall not accept subscriptions from,
or sell Units to, any persons or entities that do not qualify as (or are not
reasonably believed to be) "accredited investors," as such term is defined in
Rule 501 of Regulation D promulgated under Section 4(2) of the Securities Act of
1933, as amended (the "Act").

(d) The offering of the Units will be made by the Placement Agent on behalf of
the Company solely pursuant to the Memorandum, which at all times will be in
form and substance acceptable to the Placement Agent and its counsel and contain
such legends and other information as the Placement Agent and its counsel may,
from time to time, deem necessary and desirable to be set forth therein.
"Memorandum" as used in this Agreement means the Company's Confidential Private
Placement Memorandum, inclusive of all exhibits (including copies of the
Company's filings with the Securities and Exchange Commission (the "SEC") that
may be sent to prospective investors after the date of the Memorandum), and any
and all amendments, supplements and appendices thereto. Unless otherwise
defined, each term used in this Agreement will have the same meaning as shall be
set forth in the Memorandum.

2. Representations and Warranties. All references to the "Company" in this
Section 2 shall be deemed to include the Company's subsidiaries, as applicable.
The Company hereby represents and warrants to the Placement Agent that each of
the following shall be true in all respects as of the date hereof and, as
applicable, on and as of the date of the Memorandum as if made on and as of the
date hereof:

(a) The Memorandum will be, and as of the date of the Memorandum has been,
diligently prepared by the Company, at its sole cost, in conformity with all
applicable laws, and will in all material respects be in compliance with
Regulation D as promulgated under Section 4(2) of the Act ("Regulation D"), the
Act and the requirements of all other rules and regulations (the "Regulations")
of the SEC relating to offerings of the type contemplated by the Offering, and
the applicable securities laws and the rules and regulations of those
jurisdictions wherein the Units are to be offered and sold, excluding foreign
jurisdictions. The Units will be offered and sold pursuant to the registration
exemption provided by Regulation D and Section 4(2) and/or Section 4(6) of the
Act as a transaction not involving a public offering and the requirements of any
other applicable state securities laws and the respective rules and regulations
thereunder in those United States jurisdictions in which the Placement Agent
notifies the Company that the Units are being offered for sale. The Memorandum
will describe all material aspects, including attendant risks, of an investment
in the Company. The Company has not taken nor will it take any action that
conflicts with the conditions and requirements of, or that would make
unavailable with respect to the Offering, the exemption(s) from registration
available pursuant to Regulation D or Section 4(2) and/or Section 4(6) of the
Act and knows of no reason why any such exemption would be otherwise unavailable
to it. Neither the Company nor its affiliates has been subject to any order,

                                       2

judgment or decree of any court or governmental authority of competent
jurisdiction temporarily, preliminarily or permanently enjoining such person for
failing to comply with Section 503 of Regulation D.

(b) The Memorandum will not, and as of the date of the Memorandum does not,
include any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. None
of the statements, documents, certificates or other items prepared or supplied
by the Company with respect to the transactions contemplated hereby contains or
will contain an untrue statement of a material fact or omits a material fact
necessary to make the statements contained therein not misleading. There is no
fact that the Company has not disclosed to the Placement Agent and its counsel
in writing and of which the Company is aware that materially and adversely
affects or could materially and adversely affect the business, prospects,
financial condition, operations, assets or affairs of the Company or any of its
subsidiaries.

(c) The Company is a corporation duly organized, validly existing and in good
standing under the laws of Delaware. The Company has no subsidiaries and does
not have an equity interest in any other firm, partnership, association or other
entity other than Digital Interiors, Inc. and Home Director Technologies, Inc.
The Company directly or indirectly owns all of the outstanding capital stock of
its subsidiaries. The Company is duly qualified to transact business as a
foreign corporation and is in good standing under the laws of each jurisdiction
where the location of its properties or the conduct of its business makes such
qualification necessary, except where the failure to be so qualified would not
have a material adverse effect on the Company or its business.

(d) The Company has all requisite power and authority (corporate and other) to
conduct its business as presently conducted and as proposed to be conducted
(described in the Memorandum), to enter into and perform its obligations under
this Agreement and the other agreements contemplated hereby, and by the
Memorandum (collectively, the "Transaction Documents") and to issue, sell and
deliver the Units and the shares of Common Stock issuable upon exercise of the
Warrants (the "Conversion Shares"). The execution and delivery of each of the
Transaction Documents has been or prior to the completion of the Offering will
be, duly authorized by all necessary corporate action. This Agreement has been
duly executed and delivered and constitutes, and each of the other Transaction
Documents, upon due execution and delivery, will constitute, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, subject to any applicable bankruptcy, insolvency or
other laws affecting the rights of creditors generally and to general equitable
principles and the availability of specific performance.

(e) None of the execution and delivery of, or performance by the Company under,
any of the Transaction Documents or the consummation of the transactions herein
or therein contemplated conflicts with or violates, or will result in the
creation or imposition of, any material lien, charge or other encumbrance upon
any of the assets of the Company under any agreement or other instrument to
which the Company is a party or by which the Company or its assets may be bound,
any term of the charter or by-laws of the Company, or any license, permit,
judgment, decree, order, statute, rule or regulation applicable to the Company
or any of its assets.

                                       3

(f) The Company will have the authorized and outstanding capital stock as set
forth in the Memorandum. Except as set forth in the Memorandum, all outstanding
shares of capital stock of the Company are duly authorized, validly issued and
outstanding, fully paid and nonassessable. Except as set forth in the
Memorandum: (i) there are no outstanding options, stock subscription agreements,
warrants or other rights permitting or requiring the Company or others to
purchase or acquire any shares of capital stock, or other equity securities of
the Company, or to pay any dividend or make any other distribution in respect
thereof; (ii) there are no securities issued or outstanding that are convertible
into or exchangeable for any of the foregoing and there are no contracts,
commitments or understandings, whether or not in writing, to issue or grant any
such option, warrant, right or convertible or exchangeable security; (iii) no
shares of stock or other securities of the Company are reserved for issuance for
any purpose; (iv) there are no voting trusts or other contracts, commitments,
understandings, arrangements or restrictions of any kind with respect to the
ownership, voting or transfer of shares of stock or other securities of the
Company, including without limitation, any preemptive rights, rights of first
refusal, proxies or similar rights; and (v) except as set forth in the
Memorandum no person holds a right to require the Company to register any
securities of the Company under the Act or to participate in any such
registration. The issued and outstanding shares of capital stock of the Company
conform to all statements in relation thereto contained in the Memorandum and
the Memorandum describes all material terms and conditions thereof. All
issuances by the Company of its securities were at the time of their issuance
either (i) exempt from registration under the Act and any applicable state
securities laws or (ii) appropriately registered.

(g) The Shares, the Warrants, the Conversion Shares and the Agent's Warrants (as
defined in Section 3(e) hereof) have been duly authorized and, when issued and
delivered against payment therefor as provided in the Transaction Documents,
will be validly issued, fully paid and nonassessable and will be free and clear
of all liens, charges, restrictions, claims and encumbrances imposed by or
through the Company other than as provided in the Transaction Documents. No
holder of any of the Securities, the Conversion Shares or the Agent's Securities
(as defined in Section 3(e) hereof) will be subject to personal liability solely
by reason of being such a holder and, except as set forth in the Memorandum,
none of the Securities, the Conversion Shares or the Agent's Securities is
subject to preemptive or similar rights of any securityholder of the Company,
nor will the issuance of such securities trigger an adjustment under the
antidilution or exercise rights of any holders of any outstanding shares of
capital stock, options, warrants or other rights to acquire any securities of
the Company except as set forth in the Memorandum. Assuming that the Market
Price is equal to or greater than $0.76 at each Closing, a sufficient number of
authorized but unissued shares of Common Stock has been reserved for issuance
upon exercise of the Warrants and the exercise of the Agent's Warrants.

(h) No consent, authorization or filing of or with any court or governmental
authority is required in connection with the issuance of the Securities, the
Conversion Shares or the Agent's Securities (as defined in Section 3(e) hereof)
or the consummation of the transactions contemplated herein or in the other
Transaction Documents, except for required filings with the SEC, if any, and
applicable "blue sky" or state securities commissions relating specifically to
the Offering (all of which will be duly made on a timely basis).

                                       4

(i) Except as set forth in the Memorandum, the financial statements, together
with the related notes thereto, of the Company included or incorporated by
reference in the Memorandum are true and complete and present fairly, in all
material respects, the financial position of the Company as of the respective
dates specified and the results of its operations and changes in financial
position for the respective periods covered thereby. Such financial statements
and related notes were prepared in accordance with U.S. generally accepted
accounting principles ("GAAP") applied on a consistent basis throughout the
periods indicated except as may be disclosed in the notes thereto and except
that the unaudited financial statements omit full notes, and except for normal
year-end adjustments. Except as set forth in such financial statements or in the
Memorandum, the Company has no material liabilities of any kind, whether
accrued, absolute, contingent or otherwise or entered into any material
transactions or commitments. The other financial and statistical information
with respect to the Company included in the Memorandum present fairly the
information shown therein on a basis consistent with the financial statements of
the Company included in the Memorandum. The Company does not know of any facts,
circumstances or conditions (or any state of facts, circumstances or conditions
which management of the Company has concluded could give rise thereto) that
could materially adversely affect its business, operations, earnings or
prospects that have not been fully disclosed in the Memorandum.

(j) The conduct of business by the Company as presently and proposed to be
conducted is not subject to continuing oversight, supervision, regulation or
examination by any governmental official or body of the United States or any
other jurisdiction wherein the Company conducts or proposes to conduct such
business, except as described in the Memorandum or except such regulation as is
applicable to commercial enterprises generally. Except as set forth in the
Memorandum, all material licenses, permits, approvals, government
authorizations, leases, contracts and agreements referred to in the Memorandum,
along with all other material licenses, permits, approvals, leases, governmental
authorizations or contracts to which the Company is a party, have been obtained
and are valid and in full force and effect and neither the Company nor, to the
knowledge of the Company, any other party is in default thereunder, and to the
knowledge of the Company, no event has occurred which with the passage of time
or the giving of notice, or both, would constitute a default thereunder except
for a default which would not have a material adverse effect on the Company.
Except as described in the Memorandum, all material licenses, permits, approvals
or governmental authorizations necessary to permit the Company to conduct its
business have been obtained and are outstanding and will be outstanding on each
Closing Date, and the Company is in all material respects complying therewith.
There are no proceedings pending, or to the knowledge of the Company threatened,
seeking to cancel, terminate or limit such licenses, approvals or permits.

(k) Except as disclosed in the Memorandum, no default by the Company or, to the
best knowledge of the Company, any other party exists in the due performance
under any material agreement to which the Company is a party or to which any of
its assets is subject (collectively, the "Company Agreements"). The Company
Agreements disclosed in the Memorandum are the only material agreements to which
the Company is bound or by which its assets are subject, are accurately and
fairly described in the Memorandum and are in full force and effect in
accordance with their respective terms.

                                       5

(l) Except as set forth in the Memorandum, there are no actions, proceedings,
claims or investigations, before or by any court or governmental authority (or
any state of facts which management of the Company has concluded could give rise
thereto) pending or, to the best knowledge of the Company, threatened, against
the Company, or involving its assets or, to the knowledge of the Company,
involving any of its officers or directors which, if determined adversely to the
Company or such officer or director, could result in any material adverse change
in the condition (financial or otherwise) or prospects of the Company or
adversely affect the transactions contemplated by this Agreement or the other
Transaction Documents or the enforceability thereof.

(m) Except as set forth in the Memorandum, the Company is not in violation of:
(i) its charter or by-laws; (ii) any indenture, mortgage, deed of trust, note or
other agreement or instrument to which the Company is a party or by which it is
or may be bound or to which any of its assets may be subject; (iii) any statute,
rule or regulation currently applicable to the Company; or (iv) any judgment,
decree or order applicable to the Company, which violation or violations
individually, or in the aggregate, would result in any material adverse change
in the condition (financial or otherwise) or prospects of the Company.

(n) Except as set forth in the Memorandum and the financial statements
incorporated by reference therein, the Company does not own any real property in
fee simple, and the Company has good and marketable title to all property
(personal, tangible and intangible) owned by it, free and clear of all security
interests, liens and encumbrances except for liens imposed by law, such as
carrier's, warehouseman's, and mechanic's liens imposed in the ordinary course
of business with respect to obligations not yet due.

(o) The Company owns all right, title and interest in, or possesses adequate and
enforceable rights to use, all patents, patent applications, trademarks, trade
names, service marks, copyrights, rights, licenses, franchises, trade secrets,
confidential information, processes, formulations, software and source and
object codes reasonably necessary for the conduct of its business, except as
otherwise described in the Memorandum (collectively, the "Intangibles"). Except
as set forth in the Memorandum, the Company has not infringed upon the rights of
others with respect to the Intangibles; the Company has not received notice that
it has or may have infringed or is infringing upon the rights of others with
respect to the Intangibles, or any notice of conflict with the asserted rights
of others with respect to the Intangibles that could, individually or in the
aggregate, materially and adversely affect the business, condition (financial or
otherwise) or prospects of the Company. Except as set forth in the Memorandum,
to the best knowledge of the Company, no others have infringed or are infringing
upon the Intangibles.

(p) Except as set forth in the Memorandum and as may otherwise be contemplated
therein, the Company has operated its business diligently and only in the
ordinary course as theretofore conducted and since the date of the financial
statements incorporated by reference in the Memorandum there has been no: (i)
material adverse change in the business condition (financial or otherwise) or
prospects of the Company; (ii) transaction otherwise than in the ordinary course
of business; (iii) issuance of any securities (debt or equity) or any rights to
acquire any such

                                       6

securities; (iv) damage, loss or destruction, whether or not covered by
insurance, with respect to any asset or property of the Company; or (v)
agreement to permit any of the foregoing.

(q) Except as set forth in the Memorandum and the financial statements
incorporated by reference therein, the Company has filed, on a timely basis,
each Federal, state, local and foreign tax return which is required to be filed
by it, or has requested an extension therefor and has paid all taxes and all
related assessments, penalties and interest to the extent that the same have
become due.

(r) The Company is not obligated to pay, and has not obligated the Placement
Agent to pay, a finder's or origination fee in connection with the Offering and
agrees to indemnify the Placement Agent from any such claim made by any other
person. The Company has not offered for sale or solicited offers to purchase the
Units except for negotiations with the Placement Agent. Except as set forth in
the Memorandum, as of the commencement of the Offering, no other person has any
right to participate in any offer, sale or distribution of the Company's
securities to which the Placement Agent's rights, described herein, shall apply.

(s) The Company has and will maintain appropriate casualty and liability
insurance coverage, in scope and amounts reasonable and customary for similar
businesses.

(t) All of the Company's filings with the SEC are true and correct in all
material respects.

3. Placement Agent Appointment and Compensation.

(a) In accordance with the terms hereof, the Company hereby appoints the
Placement Agent and its selected dealers, as its exclusive agent in connection
with the Offering. The Company acknowledges that the Placement Agent may use
selected dealers and sub agents to fulfill its agency hereunder provided that
such dealers and sub agents are compensated solely by the Placement Agent.
Except as expressly stated herein, the Company has not and will not make, or
permit to be made, any offers or sales of the Units other than through the
Placement Agent without the Placement Agent's prior written consent. The
Placement Agent has no obligation to purchase any of the Units. The agency of
the Placement Agent hereunder shall continue until the earlier of the
Termination Date or the Final Closing (as defined in Section 4(c) hereof).

(b) The Company will cause to be delivered to the Placement Agent copies of the
Memorandum and has consented, and hereby consents, to the use of such copies for
the purposes permitted by the Act and applicable securities laws, and hereby
authorizes the Placement Agent and its agents, employees and selected dealers to
use the Memorandum in connection with the sale of the Units until the
Termination Date, and no other person or entity is or will be authorized to give
any information or make any representations other than those contained in the
Memorandum or to use any offering materials other than those contained in the
Memorandum in connection with the sale of the Units. The Company will provide at
its own expense such quantities of the Memorandum and other documents and
instruments relating to the Offering as the Placement Agent may reasonably
request.

                                       7

(c) The Company will cooperate with the Placement Agent by making available to
its representatives such information as may be requested in making a reasonable
investigation of the Company and its affairs and shall provide access to such
employees as shall be reasonably requested.

(d) The Company shall pay to the Placement Agent a placement fee equal to ten
percent (10%) of the gross Purchase Price Per Unit paid by each investor (the
"Placement Agent's Fee") (except that with respect to $415,000 of Units issuable
to the Company's officers, directors and their respective affiliates upon the
conversion of Bridge Notes (as defined in the Memorandum) the cash placement fee
will be 5%). In addition, the Company shall pay all expenses set forth in
Section 5(i) hereof. The Placement Agent's Fee and the expenses set forth in
Section 5(i) hereof will be deducted from the gross proceeds of the Units sold
at each Closing, as set forth in Section 4 hereof. The Placement Agent shall
direct all such amounts to be paid directly from the escrow account established
pursuant to Section 4(b) hereof.

(e) As additional compensation hereunder, at each closing, the Company shall
sell to the Placement Agent or its designees, for nominal consideration,
warrants to purchase the number of shares of Common Stock equal to twenty
percent (20%) of the Shares and Conversion Shares underlying the Warrants
purchased at each Closing (the "Agent's Warrants"), at an exercise price per
share equal to the exercise price per share of the Warrants issued at the
applicable Closing. The shares of Common Stock underlying the Agent's Warrants
shall be referred to collectively herein as the "Agent's Shares" and, together
with the Agent's Warrants, as the "Agent's Securities". The Agent's Warrants
shall be exercisable until five years after their date of issuance. The holders
of the Agent's Securities shall have registration rights equivalent to those
granted to the holders of Units. Prior to the First Closing, the Company and
Placement Agent shall agree to the form of Agent's Warrant, which shall contain
such terms and other customary provisions including cashless exercise and
weighted average anti-dilution provisions in form and substance reasonably
satisfactory to the Placement Agent and the Company.

(f) In the event any investor in the Offering or other party contacted by the
Placement Agent in connection with the Offering (except for parties that have
previously invested in the Company not as a result of an introduction by the
Placement Agent), subsequently invests in the Company at any time within
eighteen (18) months from the later of the Termination Date or the final closing
of the Offering ("Final Closing")(the "Tail Period"), the Company shall pay to
the Placement Agent the Placement Agent's Fee and a nonaccountable expense
allowance equal to 3%, and issue to the Placement Agent the Agent's Warrants
(exercisable at the subsequent investment share price) with respect to, and
based on the gross proceeds from investments in the Company made during the Tail
Period by such investors or parties.

4. Subscription and Closing Procedures.

(a) Each prospective purchaser will be required to complete and execute one
original signature page for the Subscription Agreement in the form annexed to
the Memorandum and the accredited investor certification attached thereto, which
will be forwarded or delivered to the Placement Agent at the Placement Agent's
offices at the address set forth in Section 11 hereof,

                                       8

together with the subscriber's check or good funds in the full amount of the
Purchase Price Per Unit for the number of Units desired to be purchased.

(b) All funds for subscriptions received from the Offering will be promptly
forwarded by the Placement Agent or the Company, if received by it, to and
deposited in an escrow account (the "Escrow Account") with Signature Bank,
acting as escrow agent (the "Escrow Agent") established for the purpose of
holding subscription funds prior to a Closing. All such funds for subscriptions
will be held in the Escrow Account pursuant to the terms of the escrow agreement
with respect thereto among the Company, the Placement Agent and the Escrow
Agent. The Company will pay all fees related to the establishment and
maintenance of the Escrow Account. The Placement Agent or the Company can reject
any subscriptions for any reason. Subject to the receipt of such subscriptions
for the Minimum Amount, the Company will either accept or reject the
Subscription Agreements in a timely fashion and at each Closing will countersign
the Subscription Agreements and provide copies of such agreements to the
Placement Agent. The Company will give written notice to the Placement Agent of
its acceptance or rejection of each subscription. The Company, or the Placement
Agent on the Company's behalf, will promptly return to subscribers incomplete,
improperly completed, improperly executed and rejected subscriptions and give
written notice thereof to the Placement Agent upon such return.

(c) If subscriptions for at least the Minimum Amount have been accepted prior to
the Termination Date, the funds therefor have been collected by the Escrow Agent
and all of the conditions set forth elsewhere in this Agreement are fulfilled, a
closing shall be held promptly with respect to that portion of the Units sold
(the "First Closing"). Thereafter, the remaining Units will continue to be
offered and sold until the Termination Date. Additional Closings may from time
to time be conducted at times mutually agreeable with respect to the additional
Units sold, with the Final Closing to occur within ten (10) days after the
earlier of the Termination Date or the sale of all Units offered. Delivery of
payment for the accepted subscriptions from the funds held in the Escrow Account
will be made at each Closing at the Placement Agent's offices against delivery
by the Company of the Securities comprising the Units at the address set forth
in Section 11 hereof (or at such other place as may be mutually agreed upon
between the Company and the Placement Agent), net of amounts due to the
Placement Agent and Blue Sky counsel pursuant to Section 5(i) hereof as of such
Closing. Executed Securities and the Agent's Warrants will be in such authorized
denominations and issued in such names as the Placement Agent may request on or
before the second full business day prior to the date of each Closing ("Closing
Date"), and will be made available to the Placement Agent for review and
packaging at the Placement Agent's office at least one full business day prior
thereto.

(d) If Subscription Agreements for the Minimum Amount have not been received and
accepted by the Company on or before the Termination Date for any reason, the
Offering will be terminated, no Units will be sold, and the Escrow Agent will,
at the request of the Placement Agent, cause all monies received from
subscribers for the Units to be promptly returned to such subscribers without
interest, penalty, expense or deduction.

5. Further Covenants. The Company hereby covenants and agrees that:

                                       9

(a) Except with the prior written consent of the Placement Agent, the Company
shall not, at any time prior to the Final Closing, take any action that would
cause any of the representations and warranties made by it in this Agreement not
to be complete and correct on and as of each Closing Date with the same force
and effect as if such representations and warranties had been made on and as of
each such date.

(b) If, at any time prior to the Final Closing, any event shall occur that does
or may materially affect the Company or as a result of which it might become
necessary to amend or supplement the Memorandum so that the representations and
warranties herein and therein remain true, or in case it shall, in the
reasonable opinion of counsel to the Placement Agent, be necessary to amend or
supplement the Memorandum to comply with Regulation D or any other applicable
securities laws or regulations, the Company will promptly notify the Placement
Agent and shall, at its sole cost, prepare and furnish to the Placement Agent
copies of appropriate amendments and/or supplements in such quantities as the
Placement Agent may request. The Company will not at any time, whether before or
after the Final Closing, prepare or use any amendment or supplement to the
Memorandum of which the Placement Agent will not previously have been advised
and furnished with a copy, or to which the Placement Agent or its counsel will
have objected in writing or orally (confirmed in writing within 24 hours), or
which is not in compliance with the Act, the Regulations and other applicable
securities laws. As soon as the Company is advised thereof, the Company will
advise the Placement Agent and its counsel, and confirm the advice in writing,
of any order preventing or suspending the use of the Memorandum, or the
suspension of the qualification or registration of the Units for offering or the
suspension of any exemption for such qualification or registration of the Units
for offering in any jurisdiction, or of the institution or threatened
institution of any proceedings for any of such purposes, and the Company will
use its best efforts to prevent the issuance of any such order, judgment or
decree, and, if issued, to obtain as soon as reasonably possible the lifting
thereof.

(c) The Company shall comply with the Act, the Regulations, the Securities
Exchange Act of 1934, as amended (the "1934 Act"), and the rules and regulations
thereunder, all applicable state securities laws and the rules and regulations
thereunder in the states in which the Placement Agent's Blue Sky counsel has
advised the Placement Agent that the Units are qualified or registered for sale
or exempt from such qualification or registration, so as to permit the
continuance of the sales of the Units, and will file with the SEC, and shall
promptly thereafter forward to the Placement Agent, any and all reports on Form
D as are required.

(d) The Company shall use its reasonable best efforts to qualify the Units for
sale (or seek exemption therefrom) under the securities laws of such
jurisdictions in the United States as the Placement Agent shall designate, and
the Company will (through Blue Sky counsel) make such applications and furnish
information as may be required for such purposes. The Company will, from time to
time, prepare and file such statements and reports as are or may be required to
continue such qualifications in effect for so long a period as the Placement
Agent may reasonably request. The Company shall not, however, in either case, be
required to file any general consent to service of process or to qualify as a
foreign corporation or as a dealer in securities in any jurisdiction in which it
is not so qualified or to subject itself to taxation in respect of doing
business in any jurisdiction in which it is not otherwise subject.

                                       10

(e) The Company shall place a legend on the certificates representing the
Securities issued to subscribers stating that the securities evidenced thereby
have not been registered under the Act or applicable state securities laws,
setting forth or referring to the applicable restrictions on transferability and
sale of such securities under the Act and applicable state laws.

(f) The Company shall apply the net proceeds from the sale of the Units to fund
its working capital requirements and/or for such other purposes as shall be
specifically described under "Use of Proceeds" in the Memorandum. Except as
otherwise set forth under "Use of Proceeds" in the Memorandum, the net proceeds
shall not be used to repay indebtedness to current executive officers or
principal shareholders of the Company, or to repurchase or redeem any
securities; provided, however, that notwithstanding the foregoing, the Company
may at any time repay up to $46,000 of indebtedness, plus accrued interest, to
one of its current executive officers pursuant to certain outstanding demand
loans.

(g) During the Offering Period, the Company shall make available for review by
prospective purchasers of the Units during normal business hours at the
Company's offices, upon their request, copies of the Company Agreements to the
extent that such disclosure shall not violate any applicable law or any
obligation on the part of the Company to maintain the confidentiality thereof
and shall afford each prospective purchaser of Units the opportunity to ask
questions of and receive answers from an officer of the Company concerning the
terms and conditions of the Offering and the opportunity to obtain such other
additional information necessary to verify the accuracy of the Memorandum to the
extent it possesses such information or can acquire it without unreasonable
expense and to the extent in compliance with applicable law.

(h) Except with the prior written consent of the Placement Agent, which shall
not be unreasonably withheld, or as set forth in the Memorandum with respect to
the issuance of Units, the Company shall not, at any time prior to the earlier
of the Final Closing or the Termination Date, engage in or commit to engage in
any transaction outside the ordinary course of business, including, without
limitation, the incurrence of material indebtedness; materially change its
business or operations as shall be described in the Memorandum; dispose of any
material assets or make any material acquisition; or issue, agree to issue or
set aside for issuance any securities (debt or equity) or any right to acquire
such securities, except as shall be contemplated by the Memorandum.

(i) Whether or not the transactions contemplated hereby are consummated, or this
Agreement is terminated, the Company hereby agrees to pay all fees, costs and
expenses incident hereto and to the Offering, including, without limitation,
those in connection with (i) preparing, distributing and binding the Memorandum
and any and all amendments and/or supplements thereto, fees for bound volumes
and any and all agreements, contracts and other documents related hereto and
thereto; (ii) the authorization, issuance, transfer and delivery of the Shares,
the Warrants, Conversion Shares, the Agent's Securities and the Agent's
Warrants, including, without limitation, fees and expenses of any transfer agent
or registrar; (iii) the fees and expenses of the Escrow Agent (subject to
Section 4(b) hereof); (iv) all fees and expenses of legal, accounting and other
advisers to the Company; (v) all filing fees, costs and legal fees and expenses
for Blue Sky services and related filings with respect to Blue Sky exemptions
and qualifications, including legal fees of $3,000 for

                                       11

the first ten states and $450 per state thereafter, $3,000 of which shall be
paid to the Placement Agent's counsel upon the First Closing for legal fees in
connection with obtaining Blue Sky exemptions (the "Blue Sky Fees"); and (vi)
subject to Section 9 hereof, a nonaccountable expense allowance ("Placement
Agent Expenses") relating to expenses incurred by the Placement Agent in
connection with the Offering (including, without limitation, travel and related
expenses and fees and expenses of legal, accounting and other advisers to the
Placement Agent) equal to three (3%) percent of the gross proceeds from the sale
of Units.

(j) Until the Termination Date, neither the Company nor any person or entity
acting on its behalf will negotiate or enter into any agreement with any other
placement agent or underwriter with respect to a private or public offering of
the Company's or any subsidiary's debt or equity securities. Neither the Company
nor anyone acting on its behalf will, until the Termination Date, without the
prior written consent of the Placement Agent, offer for sale to, or solicit
offers to subscribe for Units or other securities of the Company from, or
otherwise approach or negotiate in respect thereof with, any other person.

(k) At each Closing Date, (i) the independent auditors for the Company shall
have provided a "comfort letter" concerning the Company's financial statements
in the form customarily provided by Mahoney Cohen & Company in connection with
securities offerings by its audit clients and (ii) the chief executive officer
and chief financial officer of the Company shall have provided representations
and warranties relating to the Company's most recent quarterly and year-to-date
unaudited financial statements and internal financial controls, similar to those
included in the Company's 2003 annual report on Form 10-KSB under the 1934 Act,
and as required by the Sarbanes-Oxley Act of 2002.

(l) The Company hereby agrees to cooperate with Spencer Trask in exploring
strategic options, including, but not limited to investments, mergers and
acquisitions (but with no obligation to effect such a transaction).

(m) The Company hereby agrees to use commercially reasonable best efforts to
file a registration statement on Form SB-2 or other appropriate registration
document under the Act for resale of the Shares, the Conversion Shares and the
shares underlying the Placement Agent Warrants, as soon as practicable, but not
later than forty five (45) days following the Final Closing. The Company shall
use commercially reasonable best efforts to cause the effectiveness of such
registration statement on or before 90 days following the filing date of such
registration statement. If the registration statement has not been filed within
the said 45 day period, or does not become effective on or before 90 days after
the earlier of its filing and the end of such 45 day period, the Company shall
pay to each investor in the Offering as liquidated damages, an amount in cash
equal to 0.5% of the aggregate purchase price paid by such investor in the
Offering per week, until such registration statement has been filed or has been
declared effective, as applicable. The liquidated damages shall be paid to the
said investors within 10 days after the first 30 days that such amounts become
applicable and at the end of each 30 days thereafter until the applicable date
of when the registration statement is filed or becomes effective. The 45 day and
90 day periods referred to in this paragraph shall be extended by the period of
any delay in the filing or effectiveness of the registration statement
necessitated by the occurrence of one or more

                                       12

significant transactions or events affecting the Company (e.g., an acquisition
or significant commercial transaction or event outside the control of the
Company that causes the filing or effectiveness of the registration statement to
be seriously detrimental to the Company or its stockholders), which require the
Company to alter disclosure or defer the effectiveness of the Registration
Statement in order to comply with applicable securities laws, but in no event
shall any such delay exceed 60 days in any event.

6. Conditions of Placement Agent's Obligations. The obligations of the Placement
Agent hereunder are subject to the fulfillment, at or before each Closing, of
the following additional conditions:

(a) Each of the representations and warranties of the Company shall be true and
correct when made on the date hereof and on and as of each Closing Date as

of the Company or any other obligation to issue shares or other securities of
the Company, without the prior written consent of the Placement Agent.

fulfillment of the conditions set forth in subparagraphs (a), (b), (c) and (d)
above.

                                       13

(f) The Company shall have delivered to the Placement Agent (i) a currently
dated good standing certificate from the Secretary of State of Delaware and each
jurisdiction in which the Company is qualified to do business as a foreign
corporation, and (ii) certified resolutions of the Company's Board of Directors
approving this Agreement and the other Transaction Documents, and the
transactions and agreements contemplated by this Agreement and the other
Transaction Documents.

(g) At each Closing, the chief executive officer and chief financial officer of
the Company shall have provided a certificate to the Placement Agent confirming
on behalf of the Company that there have been no undisclosed material and
adverse changes in the business condition (financial or otherwise) or prospects
of the Company from the date of the latest financial statements included in the
Memorandum, the absence of material undisclosed liabilities and such other
matters relating to the financial condition and prospects of the Company that
the Placement Agent may reasonably request.

(h) At each Closing, the Company shall have (i) paid to the Placement Agent the
Placement Agent's Fee in respect of all Units sold at such Closing, (ii) paid
all fees, costs and expenses set forth in Section 5(i) hereof, and (iii)
executed and delivered to the Placement Agent the Agent's Warrants in an amount
proportional to the Units sold at such Closing.

(i) There shall have been delivered to the Placement Agent a signed opinion of
counsel to the Company ("Company Counsel"), dated as of each Closing Date, in
substantially the form attached hereto as Exhibit A.

(j) All actions taken at or prior to each Closing and related documentation in

all such documents, certificates and opinions as they may reasonably request
upon reasonable prior notice in connection with the transactions contemplated
hereby.

(k) The Placement Agent shall be satisfied with the results of its due diligence
investigation of the Company.

7. Indemnification.

(a) The Company will (i) indemnify and hold harmless the Placement Agent, its
selected dealers and their respective officers, directors, employees and each
person, if any, who controls the Placement Agent within the meaning of the Act
and such selected dealers (each an "Indemnitee") against, and pay or reimburse
each Indemnitee for, any and all losses, claims, damages, liabilities or
expenses whatsoever (or actions or proceedings or investigations in respect
thereof), joint or several (which will, for all purposes of this Agreement,
include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees, including appeals), to which
any Indemnitee may become subject, under the Act or otherwise, in connection
with the offer and sale of the Units, whether such losses, claims, damages,
liabilities or expenses shall result from any claim of any Indemnitee or any
third party; and (ii) reimburse each Indemnitee for

                                       14

any legal or other expenses reasonably incurred in connection with investigating
or defending against any such loss, claim, action, proceeding or investigation;
provided, however, that the Company will not be liable in any such case to the
extent that any such claim, damage or liability results from (A) an untrue
statement or alleged untrue statement of a material fact made in the Memorandum,
or an omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, in
reliance upon and in conformity with written information furnished to the
Company by the Placement Agent or any such controlling persons specifically for
use in the preparation thereof, or (B) any violations by the Placement Agent of
the Act or state securities laws which does not result from a violation thereof
or a breach hereafter by the Company or any of its affiliates. In addition to
the foregoing agreement to indemnify and reimburse, the Company will indemnify
and hold harmless each Indemnitee against any and all losses, claims, damages,
liabilities or expenses whatsoever (or actions or proceedings or investigations
in respect thereof), joint or several (which shall for all purposes of this
Agreement, include, but not be limited to, all costs of defense and
investigation and all reasonable attorneys' fees, including appeals) to which
any Indemnitee may become subject insofar as such costs, expenses, losses,
claims, damages or liabilities arise out of or are based upon the claim of any
person or entity that he or it is entitled to broker's or finder's fees from any
Indemnitee in connection with the Offering.

(b) The Placement Agent will indemnify and hold harmless the Company, its
officers, directors, employees and each person, if any, who controls the Company
within the meaning of the Act against, and pay or reimburse any such person for,
any and all losses, claims, damages or liabilities or expenses whatsoever (or
actions, proceedings or investigations in respect thereof) to which the Company
or any such person may become subject under the Act or otherwise, whether such
losses, claims, damages, liabilities or expenses (or actions, proceedings or
investigations in respect thereof) shall result from any claim of the Company,
any of its officers, directors, employees, agents, any person who controls the
Company within the meaning of the Act or any third party, insofar as such
losses, claims, damages or liabilities are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Memorandum but
only with reference to information contained in the Memorandum relating to the
Placement Agent, or an omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, if made or omitted in reliance upon and in conformity with
written information furnished to the Company by the Placement Agent or any such
controlling persons, specifically for use in the preparation thereof. The
Placement Agent will reimburse the Company or any such person for any legal or
other expenses reasonably incurred in connection with investigating or defending
against any such loss, claim, damage, liability or action, proceeding or
investigation to which such indemnity obligation applies. Notwithstanding the
foregoing, in no event shall the Placement Agent's indemnification obligation
hereunder exceed the amount of the Placement Agent's Fees actually received by
it.

(c) Promptly after receipt by an indemnified party under this Section 7 of
notice of the commencement of any action, claim, proceeding or investigation
("Action"), such indemnified party, if a claim in respect thereof is to be made
against the indemnifying party under this Section 7, will notify the
indemnifying party of the commencement thereof, but the omission to so notify
the indemnifying party will not relieve it from any liability which it may have
to any

                                       15

indemnified party under this Section 7 unless the indemnifying party has been
substantially prejudiced by such omission. The indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
any other indemnifying party, to assume the defense thereof subject to the
provisions herein stated, with counsel reasonably satisfactory to such
indemnified party. The indemnified party will have the right to employ separate
counsel in any such Action and to participate in the defense thereof, but the
fees and expenses of such counsel will not be at the expense of the indemnifying
party if the indemnifying party has assumed the defense of the Action with
counsel reasonably satisfactory to the indemnified party; provided, however,
that if the indemnified party shall be requested by the indemnifying party to
participate in the defense thereof or shall have concluded in good faith and
specifically notified the indemnifying party either that there may be specific
defenses available to it which are different from or additional to those
available to the indemnifying party or that such Action involves or could have a
material adverse effect upon it with respect to matters beyond the scope of the
indemnity agreements contained in this Agreement, then the counsel representing
it, to the extent made necessary by such defenses, shall have the right to
direct such defenses of such Action on its behalf and in such case the
reasonable fees and expenses of such counsel in connection with any such
participation or defenses shall be paid by the indemnifying party. No settlement
of any Action against an indemnified party will be made without the consent of
the indemnifying party and the indemnified party, which consent shall not be
unreasonably withheld or delayed in light of all factors of importance to such
party and no indemnifying party shall be liable to indemnify any person for any
settlement of any such claim effected without such indemnifying party's consent.

8. Contribution. To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 7 hereof
and it is finally determined, by a judgment, order or decree not subject to
further appeal that such claims for indemnification may not be enforced, even
though this Agreement expressly provides for indemnification in such case; or
(ii) any indemnified or indemnifying party seeks contribution under the Act, the
1934 Act, or otherwise, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Placement Agent on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Placement Agent on the other
shall be deemed to be in the same proportion as the total net proceeds from the
Offering (before deducting expenses) received by the Company bear to the total
commissions and fees received by the Placement Agent. The relative fault, in the
case of an untrue statement, alleged untrue statement, omission or alleged
omission will be determined by, among other things, whether such statement,
alleged statement, omission or alleged omission relates to information supplied
by the Company or by the Placement Agent, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement, alleged statement, omission or alleged omission. The Company and the
Placement Agent agree that it would be unjust and inequitable if the respective
obligations of the Company and the Placement Agent for contribution were
determined by pro rata allocation of the aggregate losses, liabilities, claims,
damages and expenses or by any other method or allocation that does not reflect
the equitable considerations referred to in this Section 8. No person guilty of
a fraudulent misrepresentation

                                       16

(within the meaning of Section 11(f) of the Act) will be entitled to
contribution from any person who is not guilty of such fraudulent
misrepresentation. For purposes of this Section 8, each person, if any, who
controls the Placement Agent within the meaning of the Act will have the same
rights to contribution as the Placement Agent, and each person, if any, who
controls the Company within the meaning of the Act will have the same rights to
contribution as the Company, subject in each case to the provisions of this
Section 8. Anything in this Section 8 to the contrary notwithstanding, no party
will be liable for contribution with respect to the settlement of any claim or
action effected without its written consent. This Section 8 is intended to
supersede, to the extent permitted by law, any right to contribution under the
Act, the 1934 Act or otherwise available.

9. Termination.

(a) (I) The Offering may be terminated by the Placement Agent at any time prior
to the expiration of the Offering Period in the event that (i) any of the
representations or warranties of the Company contained herein shall have been
false or misleading in any material respect when made or deemed made, (ii) the
Company shall have failed to perform any of its obligations hereunder, (iii) the
Company shall have determined for any reason not to continue with the Offering
or (iv) the Placement Agent shall determine in its sole discretion, reasonably
exercised, that it is reasonably likely that any of the conditions to Closing
set forth herein will not, or cannot, be satisfied. In the event of any such
termination occasioned by or arising out of or in connection with the matters
set forth in clauses (i)-(iii) above, or occasioned by or arising out of or in
connection with a matter set forth in clause (iv) above due to any breach or

been suspended or a general banking moratorium shall have been established by

EXHIBIT A

                              FORM OF LEGAL OPINION

The phrase "Transaction Documents," whenever it is used in this letter, means
(a) the Placement Agency Agreement dated as of _____________, 2004 by and among
Home Director, Inc. (the "Company") and Spencer Trask Ventures, Inc. (the
"Placement Agent") (such agreement, the "Placement Agency Agreement"), (b) the
Placement Agent Warrant dated as of ___________, 2004 (the "Placement Agent
Warrant") and (c) the Subscription Agreement, dated as of______________, 2004,
by and among the Company and each investor signatory thereto (such investors,
the "Investors" and such agreement, the "Subscription Agreement"), the Escrow
Agreement, the Warrant, the Registration Rights Agreement and all other
certificates and documents required to be executed and delivered by the Company
pursuant to the Placement Agent Agreement. All capitalized terms used in this
letter have the respective meanings set forth in the Placement Agency Agreement
unless otherwise defined herein.

(i) The Company and each of its subsidiaries have been duly organized as a
corporation and are validly existing and in good standing under the laws of
their respective jurisdictions of organization, have full corporate power and
authority (corporate and otherwise) to own, lease and operate their properties
and conduct their business as described in the Memorandum and are duly qualified
as a foreign corporation for the transaction of business and are in good
standing in each jurisdiction where the conduct of its business makes such
qualification necessary, except where the failure to so qualify would not have a
material adverse effect upon the business (as currently conducted), financial
condition or results of operation of the Company (a "Material Adverse Effect").

(ii) The Company has the full corporate power and authority to execute and
deliver the Transaction Documents and to perform its obligations thereunder. The
execution, delivery and performance thereof and thereunder has been duly
authorized by all necessary corporate action. Each of the Transaction Documents
has been duly executed and delivered on behalf of the Company, and constitutes
legal, valid and binding obligations of the Company, enforceable against it in
accordance with its terms except as such enforceability may be limited by
applicable bankruptcy, insolvency or laws affecting creditor's rights or
remedies and general principles of equity.

(iii) To our knowledge, the Company has an authorized and outstanding capital
stock as set forth in the Memorandum and the outstanding shares of capital stock
of the Company have been duly authorized and are validly issued, fully paid and
nonassessable and were not issued in violation of, or subject to, any statutory,
or to our knowledge, contractual or other preemptive rights. The Units, the
components thereof, Conversion Shares and the Agent's Shares have been duly
authorized, and when duly and validly delivered and paid for pursuant to the
terms of the Transaction Documents will be validly issued, fully paid and
nonassessable. Except as set forth in

                                       22

the Confidential Private Placement Memorandum (the "Memorandum"), the issuance
of the Units, Conversion Shares or the Agent's Securities are not subject to
statutory, or to our knowledge, contractual or other preemptive rights of any
stockholder of the Company. The Units, Conversion Shares and the Agent's
Securities conform in all material respects with the descriptions thereof
contained in the Memorandum. A sufficient number of authorized but unissued
shares of Common Stock have been reserved for issuance upon conversion or
exercise of the components of the Units and exercise of the Agent's Warrants if
such Warrants had been exercised on the date hereof.

(iv) None of the execution and delivery of, or performance by the Company under,
any of the Transaction Documents or the consummation of the transactions therein
contemplated, will conflict with or violate (a) any term of the charter or
by-laws of the Company or any subsidiary, (b) any statute, rule, regulation or
ordinance or (c) any permit, judgment, decree, or order known to us which is
applicable to the Company, its subsidiaries or any of their respective assets,
properties or businesses.

(v) To our knowledge, except as provided in the Transaction Documents none of
the execution and delivery of, or performance by the Company under, any of the
Transaction Documents or the consummation of the transactions therein
contemplated, will conflict with or result in the creation or imposition of, any
lien, charge or other encumbrance upon any of the properties or assets of the
Company or its subsidiaries pursuant to the terms of any material indenture,
mortgage, deed of trust, note, material license, agreement or other instrument
filed as an Exhibit to the Company's SEC reports to which the Company or any
subsidiary is a party or by which the Company or any subsidiary may be bound or
to which any of their respective assets, properties or businesses is or may be
subject.

(vi) No consent, approval, authorization, order, registration or qualification
of or with any court or regulatory, administrative or governmental agency, body
or authority of the United States of America or any political subdivision
thereof is required in connection with the issuance or sale of the Units or the
Agent's Warrants except for required filings with the United States Securities
and Exchange Commission and applicable "Blue Sky" or state securities
commissions relating specifically to the Offering.

(vii) To our knowledge, except as set forth in the Memorandum, there are no
legal or regulatory, administrative or governmental charges, actions, suits,
proceedings, claims, hearings or investigations, before or by any court,
governmental authority, or instrumentality pending or threatened against the
Company, any of its subsidiaries, or involving their respective assets or
properties or any of their officers or directors which, if determined adversely
to the Company, could have a Material Adverse Effect on the Company or adversely
affect any of the transactions contemplated by the Transaction Documents or the
validity or enforceability thereof.

(viii) To our knowledge except as provided in the Memorandum, neither the
Company nor any of its subsidiaries is in violation or breach of: (i) its
charter or by-laws, (ii) any statute, rule, regulation or ordinance under the
Delaware General Corporation Law or federal securities law; (iii) any material
indenture, mortgage, deed of trust, note or other agreement or instrument to

                                       23

which the Company or any of its subsidiaries is a party or by which it is or may
be bound or to which any of its assets, properties or businesses may be subject
and which have been filed as an exhibit to the Company's SEC reports; or (iv)
any judgment, decree or order applicable to the Company or any subsidiary which
violation or violations individually, or in the aggregate, might result in any
Material Adverse Effect in the condition (financial or otherwise), or prospects
of the Company.

(ix) To our knowledge, the descriptions in the Memorandum of contracts and other
documents are accurate in all material respects and such descriptions fairly
present in all material respects the information required to be shown. To our
knowledge, there are no contracts or other documents of a character required to
be referred to in the Memorandum other than those described or referred to
therein.

(x) To our knowledge, the Company and its subsidiaries have obtained all
authorizations, approvals, licenses, permits, franchises and orders of and from
all governmental officials and bodies to own or lease and operate its assets and
properties (the "Authorizations") and to conduct its business as currently
conducted as described in the Memorandum; all of such Authorizations are to the
best of our knowledge in full force and effect and the Company and its
subsidiaries are in all material respects complying therewith and there are, to
the best of our knowledge of such counsel no proceedings pending or threatened
seeking to cancel or terminate such Authorizations.

(xi) We have participated in the preparation of the Memorandum and in
conferences with officers and other representatives of the Company, at which
such conferences the contents of the Memorandum and related matters were
discussed, and based upon those conferences and upon such counsel's
participation in the preparation of the Memorandum, and any amendment or
supplement thereto, nothing has come to our attention that causes us to believe
that the Memorandum (other than the financial statements including the notes
thereto, and other than the supporting schedules and other financial and
statistical information included in the Memorandum), contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements therein not misleading in light of the
circumstances in which they were made.

(xii) Assuming that the Units were sold only to "accredited investors" (as
defined in Rule 501 of Regulation D) and the Placement Agent complied in all
material respects with Regulation D, such sales were made in conformity in all
material respects with the requirements of Sections 4(2) of the Act and and/or
Rule 506 of Regulation D and the issuance of the Units in accordance with the
Memorandum is exempt from registration under the Securities Act of 1933, as
amended.
