                                                              EXECUTED VERSION

EXHIBIT 4.4

                          REGISTRATION RIGHTS AGREEMENT

      THIS REGISTRATION RIGHTS AGREEMENT, dated as of June 11, 2001 (this
"Agreement"), is made by and between FLOUR CITY INTERNATIONAL, INC., a Nevada
corporation (the "Company"), and DIMENSIONAL PARTNERS, L.P. and DIMENSIONAL
PARTNERS, LTD. (together, the "Purchasers").

                              W I T N E S S E T H:

      WHEREAS, pursuant to a Securities Purchase Agreement, dated as of the date
hereof, between the Company and the Purchasers (the "Securities Purchase
Agreement"), the Company has agreed to issue and sell to the Purchasers, (i)
$2,500,000 aggregate principal amount of the Company's 8 1/2% Subordinated
Secured Convertible Debentures (the "Debentures") and (ii) warrants (the
"Warrants") to purchase an initial aggregate number of 389,916 shares (as such
number may be adjusted pursuant to the terms of the Warrants) of the Company's
Common Stock, par value $.0001 per share (the "Common Stock");

      WHEREAS, pursuant to the terms of the Debentures and the Warrants, upon
the conversion of the Debentures and upon the exercise of the Warrants, the
Company will, in each case, issue to the Purchaser or its permitted assigns
shares of Common Stock (such shares of Common Stock are collectively referred to
herein as the "Registrable Securities"); and

      WHEREAS, to induce the Purchasers to execute and deliver the Securities
Purchase Agreement, the Company has agreed to provide to the Purchasers and
their permitted assigns certain registration rights under the Securities Act of
1933, as amended (the "Securities Act"), and applicable state securities laws.

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Purchasers
hereby agree as follows:

      1.    DEFINITIONS.

            As used in this Agreement, the following terms shall have the
following meanings:

                  (a) "Holder" or "Holders" mean a holder or holders of
Registrable Securities or securities convertible into or exercisable for
Registrable Securities.

                  (b) "Registration Statement" means a registration statement or
registration statements of the Company filed under the Securities Act covering
Registrable Securities.

<PAGE>

                  (c) "Register," "Registered" and "Registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act and pursuant to Rule 415 under the Securities
Act or any successor rule providing for offering securities on a continuous
basis ("Rule 415"), and the declaration or ordering of effectiveness of such
registration statement by the United States Securities and Exchange Commission
(the "Commission").

      Capitalized terms used herein and not otherwise defined herein shall have
the meanings set forth in the Securities Purchase Agreement.

      2.    MANDATORY REGISTRATIONS.

                  (a) REGISTRATION STATEMENT. The Company shall, as soon as
practicable, but in no event later than 90 days after the date hereof (the
"Filing Deadline"), prepare and file with the Commission a Registration
Statement or Registration Statements (as necessary) on Form S-3 covering the
resale of all of the Registrable Securities. In the event that Form S-3 is
unavailable and/or inappropriate for such a registration, the Company shall use
such other form as is available and appropriate for such a registration. Any
Registration Statement prepared pursuant hereto shall register for resale at
least that number of shares of Common Stock equal to the sum of (i) the maximum
number of Registrable Securities that are issuable upon conversion of the
Debentures, on the date of filing, and (ii) the maximum number of Registrable
Securities issuable upon exercise of the Warrants, in each case, without regard
to any limitation on any holder's ability to convert any of the Warrants or the
Debentures (such product, the "Registrable Amount"). Such Registration Statement
shall state that, in accordance with Rule 416 under the Securities Act, it also
covers such indeterminate number of additional shares of Common Stock ("Shares")
as may become issuable upon conversion of the Debentures or exercise of the
Warrants (i) resulting from any adjustment in the applicable conversion price of
the Debentures or exercise price of the Warrants or (ii) to prevent dilution
resulting from stock splits, stock dividends, recapitalizations,
reclassifications, distributions, consolidations, mergers or similar
transactions. If at any time the Registrable Amount exceeds the total number of
Shares so registered, the Company shall, within ten (10) business days after
receipt of a written notice from the Purchasers, either (i) amend the
Registration Statement or Registration Statements filed by the Company pursuant
to this section, if such Registration Statement has not been declared effective
by the Commission at that time, to register the Registrable Amount of Shares, or
(ii) if such Registration Statement has been declared effective by the
Commission at that time, file with the Commission an additional Registration
Statement on Form S-3 or such other appropriate form, to register the number of
Shares by which the Registrable Amount exceeds the number of Shares already
registered. The Company shall use its best efforts to cause the Registration
Statement to be declared effective not later than one hundred eighty (180) days
following the Closing Date (the "Effectiveness Deadline").

                  (b) The Company shall use its best efforts to keep each
Registration Statement effective pursuant to Rule 415 at all times until such
date as is the earlier of (i) the date on which all of the Registrable
Securities have been sold and (ii) the date on which the Registrable Securities
(in the opinion of counsel to the Purchasers) may be immediately sold

                                       2

<PAGE>

without restriction (including without limitation as to volume by each holder
thereof) without registration under the Securities Act (the "Registration
Period").

                  (c) If any offering pursuant to a Registration Statement
pursuant to Section 2 hereof involves an underwritten offering (which may only
be with the consent of the Company), the Purchasers shall have the right to
select legal counsel and an investment banker or bankers and manager or managers
to administer the offering, which investment banker or bankers or manager or
managers shall be reasonably satisfactory to the Company.

      3.    OBLIGATIONS OF THE COMPANY.  In connection  with the  registration
of the Registrable Securities, the Company shall do each of the following:

            (a) Prepare and file with the Commission the Registration Statements
required by Section 2 of this Agreement and such amendments (including
post-effective amendments) and supplements to the Registration Statements and
the prospectuses used in connection with the Registration Statements, each in
such form as to which the Purchasers and their counsel shall not have objected,
as may be necessary to keep the Registration current at all times during the
Registration Period, and, during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all of the
Registrable Securities until such time as all of such Registrable Securities
have been disposed of in accordance with the intended methods of disposition by
the seller or sellers thereof as set forth in the Registration Statements;

            (b) Furnish to the Purchasers, if the Registrable Securities of the
Purchasers are included in the Registration Statement, and their legal counsel
identified to the Company, promptly after the same is prepared and publicly
distributed, filed with the Commission, or received by the Company, a copy of
the Registration Statement, each preliminary prospectus, each final prospectus,
and all amendments and supplements thereto and such other documents, as the
Purchasers may reasonably request in order to facilitate the disposition of
their Registrable Securities;

            (c) As soon as practicable, furnish to the Purchasers and their
counsel copies of any correspondence between the Company and the Commission with
respect to any registration statement or amendment or supplement thereto filed
pursuant to this Agreement;

            (d) Use all best efforts to (i) register and qualify the Registrable
Securities covered by the Registration Statement under such other securities or
blue sky laws of such jurisdictions as the Purchasers may request, (ii) prepare
and file in those jurisdictions such amendments (including post-effective
amendments) and supplements to such registrations and qualifications as may be
necessary to maintain the effectiveness thereof at all times during the
Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period and (iv) take all other actions necessary or advisable to
qualify the Registrable Securities for sale in such jurisdictions;

                                       3

<PAGE>

            (e) List such securities on The Nasdaq Stock Market and all the
other national securities exchanges on which any securities of the Company are
then listed, and file any filings required by The Nasdaq Stock Market and/or
such other exchanges;

            (f) As promptly as practicable after becoming aware of such event,
notify each Purchaser of the occurrence of any event of which the Company has
knowledge as a result of which the prospectus included in the 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 in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading, and to use its best efforts to promptly prepare a
supplement or amendment to the Registration Statement or other appropriate
filing with the Commission to correct such untrue statement of omission, and to
deliver a number of copies of such supplement or amendment to the Purchasers as
the Purchasers may reasonably request;

            (g) As promptly as practicable after becoming aware of such event,
notify each Purchaser who holds Registrable Securities being sold (or, in the
event of an underwritten offering, the managing underwriters) of the issuance by
the Commission of any stop order or other suspension of the effectiveness of the
Registration Statement at the earliest possible time, and to use its best
efforts to promptly obtain the withdrawal of such stop order or other suspension
of effectiveness (the occurrence of any of the events described in paragraphs
(f) and (g) of this Section 3 is referred to herein as a "Blackout Event"), and
no Purchaser shall, during the continuation of a Blackout Event, sell any
Registrable Securities pursuant to a Registration Statement after the Company
has given notice to such Purchaser pursuant to the terms hereof that such
Registration Statement is subject to a Blackout Event;

            (h) If the Company has consented to an underwritten offering and
such offering is underwritten, at the request of a Purchaser, to furnish on the
date that Registrable Securities are delivered to the underwriters for sale
pursuant to such registration: (i) an opinion dated such date of counsel
representing the Company for the purposes of such registration, addressed to the
underwriters and to any Purchaser selling Registrable Securities in connection
with such underwriting, stating that such registration statement has become
effective under the Securities Act and that (A) to the best knowledge of such
counsel, no stop order suspending the effectiveness thereof has been issued and
no proceedings for that purpose have been instituted or are pending or
contemplated under the Securities Act and (B) the registration statement, the
related prospectus and each amendment or supplement thereof comply as to form in
all material respects with the requirements of the Securities Act (except that
such counsel need not express any opinion as to financial statements or other
financial data contained therein) and (ii) a letter dated such date from the
Company's independent public accountants addressed to the underwriters and to
such Purchasers, stating that they are independent public accountants within the
meaning of the Securities Act and that, in the opinion of such accountants, the
financial statements of the Company included in the registration statement or
the prospectus, or any amendment or supplement thereof, comply as to form in all
material respects with the applicable accounting requirements of the Securities
Act, and such letter shall additionally cover such other financial matters
(including information as to the period ending no more than five (5) business

                                       4

<PAGE>

days prior to the date of such letter) with respect to such registration as such
underwriters may reasonably request;

            (i) Cooperate with the Purchasers to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be
offered pursuant to the Registration Statement and to enable such certificates
for the Registrable Securities to be in such denominations or amounts, as the
case may be, as the Purchasers may reasonably request, and registered in such
names as the Purchasers may request; and, within three (3) business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the Commission, the Company shall deliver, and shall cause legal
counsel selected by the Company to deliver, to the transfer agent for the
Registrable Securities (with copies to the Purchasers) an appropriate
instruction and opinion of such counsel;

            (j) Enter into customary agreements (including, in the case of an
underwritten offering, underwriting agreements in customary form, and including
provisions with respect to indemnification and contribution in customary form
and consistent with the provisions relating to indemnification and contribution
contained herein) and take all other customary and appropriate actions in order
to expedite or facilitate the disposition of such Registrable Securities and in
connection therewith:

                  (i) make such representations and warranties to the Purchasers
and the underwriters, if any, in form, substance and scope as are customarily
made by issuers to underwriters in similar underwritten offerings;

                  (ii) to the extent requested and customary for the relevant
transaction, enter into a securities sales agreement with the Purchasers and
such representative of the Purchasers as the Purchasers covered by any
Registration Statement shall select relating to the Registration and providing
for, among other things, the appointment of such representative as agent for the
selling Purchasers for the purpose of soliciting purchases of Registrable
Securities, which agreement shall be customary in form, substance and scope and
shall contain customary representations, warranties and covenants; and

                  (iii) deliver such customary documents and certificates as may
be reasonably requested by the Purchasers whose Registrable Securities are being
sold or by the managing underwriters, if any.

The above shall be done (i) at the effectiveness of such Registration Statement
(and each post-effective amendment thereto) in connection with any registration,
and (ii) at each closing under any underwriting or similar agreement as and to
the extent required thereunder;

            (k) The Company shall, at the request of the Purchasers, make
generally available to its security holders as soon as practicable, but not
later than ninety (90) days after the close of the period covered thereby, an
earnings statement (in form complying with the provisions of Rule 158 under the
Securities Act) covering a twelve-month period beginning not

                                       5

<PAGE>

later than the first day of the Company's fiscal quarter next following the
effective date of a Registration Statement;

            (l) The Company shall make available for inspection by (i) any
Purchaser, (ii) any underwriter participating in any disposition pursuant to a
Registration Statement, (iii) one firm of attorneys and one firm of accountants
or other agents retained by the Purchasers, and (iv) one firm of attorneys
retained by all such underwriters (collectively, the "Inspectors") all pertinent
financial and other records, and pertinent corporate documents and properties of
the Company (collective, the "Records"), as shall be reasonably deemed necessary
by each Inspector to enable each Inspector to exercise its due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information which any Inspector may reasonably request for purposes
of such due diligence; provided, however, that each Inspector shall hold in
confidence and shall not make any disclosure (except to the Inspectors) of any
Record or other information which the Company determines in good faith to be
confidential, and of which determination the Inspectors are so notified, unless
(a) the disclosure of such Records is necessary to avoid or correct a material
misstatement or omission in any Registration Statement, (b) the release of such
Records is ordered pursuant to a subpoena or other order from a court or
government body of competent jurisdiction, or (c) the information in such
Records has been made generally available to the public other than by disclosure
in violation of this or any other agreement. The Company shall not be required
to disclose any confidential information in such Records to any Inspector until
and unless such Inspector shall have entered into confidentiality agreements (in
form and substance satisfactory to the Company) with the Company with respect
thereto, substantially in the form of this Section 3(m). Each Purchaser agrees
that upon learning that the release of such Records is ordered pursuant to a
subpoena or other order from a court or government body of competent
jurisdiction, it shall give prompt notice to the Company and allow the Company,
at its expense, to undertake appropriate action to prevent disclosure of, or to
obtain a protective order for, the Records deemed confidential. Nothing herein
shall be deemed to limit the Purchasers' ability to sell Registrable Securities
in a manner which is otherwise consistent with applicable laws and regulations;
and

            (m) The Company shall hold in confidence and not make any disclosure
of information concerning a Purchaser provided to the Company unless (i)
disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other order
from a court or governmental body of competent jurisdiction, or (iv) such
information has been made generally available to the public other than by
disclosure in violation of this or any other agreement. The Company agrees that
it shall, upon learning that disclosure of such information concerning a
Purchaser is sought in or by a court or governmental body of competent
jurisdiction or though other means, give prompt notice to such Purchaser prior
to making such disclosure, and allow the Purchaser, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information.

      4. OBLIGATIONS OF THE PURCHASERS. In connection with the registration of
the Registrable Securities, each Purchaser shall furnish to the Company such
information regarding

                                       6

<PAGE>

itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it as shall be reasonably
required to effect the registration of such Registrable Securities, and each
Purchaser shall execute such documents in connection with such registration
as the Company may reasonably request. At least five (5) days prior to the
first anticipated filing date of the Registration Statement, the Company
shall notify the Purchasers of the information the Company included in the
Registration Statement. No Purchaser shall, during the continuation of a
Blackout Event, sell any Registrable Securities pursuant to a Registration
Statement after the Company has given notice to such Purchaser pursuant to
the terms hereof that such Registration Statement is subject to a Blackout
Event.

      5. EXPENSES OF REGISTRATION. All expenses, other than underwriting
discounts and commissions and other fees and expenses of investment bankers and
other than brokerage commissions, incurred in connection with registrations,
filings or qualifications pursuant to Section 3, but including, without
limitation, all registration, listing, and qualification fees, printing and
accounting fees, and the fees and disbursements of counsel for the Company, and
the fees of one counsel to the Purchasers with respect to each Registration
Statement filed pursuant hereto, shall be borne by the Company provided, that
the expenses of such Purchasers' counsel shall not exceed $15,000.

      6.    INDEMNIFICATION.  In the  event  any  Registrable  Securities  are
included in a Registration Statement under this Agreement:

            (a) The Company will indemnify and hold harmless each Purchaser,
each of its officers, directors, partners and shareholders, and each person, if
any, who controls each Purchaser within the meaning of the Securities Act or the
Exchange Act (each, an "Indemnified Person"), against any losses, claims,
damages, liabilities or expenses (joint or several) incurred (collectively,
"Claims") to which any of them may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon: (i) any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or any post-effective amendment thereof
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances in which they were made, not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the effective date of such Registration
Statement, or contained in the final prospectus (as amended or supplemented, if
the Company files any amendment thereof or supplement thereto with the
Commission) or the omission to state therein any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state or
foreign securities law or any rule or regulation under the Securities Act, the
Exchange Act or any state or foreign securities law (the matters in foregoing
clauses (i) through (iii) being, collectively, "Violations"). The Company shall,
subject to the provisions of Section 6(b) below, reimburse each Purchaser,
promptly as such expenses are incurred and are due and payable, for any legal
and other costs, expenses and disbursements in giving testimony or furnishing
documents in response to a subpoena or otherwise, including without limitation,
the

                                       7

<PAGE>

costs, expenses and disbursements, as and when incurred, of investigating,
preparing or defending any such action, suit, proceeding or investigation
(whether or not in connection with litigation in which the Purchaser is a
party), incurred by it in connection with the investigation or defense of any
such Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a) shall not (i) apply
to any Claim arising out of or based upon a modification which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by or on behalf of any Indemnified Person expressly for use in
connection with the preparation of the Registration Statement or any such
amendment thereof or supplement thereto; (ii) with respect to any preliminary
prospectus, inure to the benefit of any such person from whom the person
asserting any such Claim purchased the Registrable Securities that are the
subject thereof (or to the benefit of any person controlling such person) if
the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected in the final prospectus, as then amended
or supplemented, if such final prospectus was timely made available by the
Company pursuant to Section 3(b) hereof; (iii) be available to the extent
that such Claim is based upon a failure of the Purchaser to deliver or to
cause to be delivered the prospectus made available by the Company, if such
prospectus was timely made available by the Company pursuant to Section 3(b)
hereof; or (iv) apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of the Company,
which consent shall not be unreasonably withheld. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf
of the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Purchaser pursuant to Section 9. Each Purchaser will
indemnify the Company and its officers and directors against any Claims
arising out of or based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing to the Company, by or on
behalf of the Purchaser, expressly for use in connection with the preparation
of the Registration Statement (including any modifications, amendments or
supplements thereto), subject to such limitations and conditions as are
applicable to the Indemnification provided by the Company in this Section 6;
provided, however, that in no event shall any indemnity by any Purchaser
under this Section 6 exceed the amount of the net proceeds received by such
Purchaser in connection with the offering effected through such Registration
Statement.

            (b) Promptly after receipt by an Indemnified Person under this
Section 6 of notice of the commencement of any action (including any
governmental action), such Indemnified Person shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and to the
extent that the indemnifying party so desires, jointly with any other
indemnifying party similarly notified, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person, provided, however, that an Indemnified Person shall have the right to
retain its own counsel with the reasonable fees and expenses to be paid by the
indemnifying party, if, in the reasonable opinion of counsel retained by the
indemnifying party, the representation by such counsel of the Indemnified Person
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person and any other party
represented by such counsel in such proceeding. In

                                       8

<PAGE>

such event, the Company shall pay for only one separate legal counsel for the
Purchasers, and such legal counsel shall be selected by the Purchasers. The
failure to deliver written notice to an indemnifying party within a
reasonable time after the commencement of any such action shall not relieve
such indemnifying party of any liability to the Indemnified Person under this
Section 6, except to the extent that the indemnifying party is materially
prejudiced in its ability to such action. The indemnification required by
this Section 6 shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as such expense, loss,
damage or liability is incurred and is due and payable.

            (c) No indemnifying party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Person of an unconditional and irrevocable release from all
liability in respect of such claim or litigation.

            (d) Notwithstanding the foregoing, to the extent that any provisions
relating to indemnification or contribution contained in the underwriting
agreements entered into among the Company, the underwriters and the Purchasers
in connection with the underwritten public offering are in conflict with the
foregoing provisions, the provisions in such underwriting agreements shall be
controlling as to the Registrable Securities included in the public offering;
PROVIDED, HOWEVER, that if, as a result of this Section 6(d), a Purchaser, its
officers, directors, partners, shareholders or any person controlling the
Purchaser is or are held liable with respect to any Claim for which they would
be entitled to indemnification hereunder but for this Section 6(d) in an amount
which exceeds the aggregate proceeds received by the Purchaser from the sale of
Registrable Securities included in a registration pursuant to such underwriting
agreement (the "Excess Liability"), the Company shall reimburse the Purchasers
for such Excess Liability.

      7. CONTRIBUTION. To the extent any indemnification by an indemnifying
party is prohibited or limited under applicable law, the indemnifying party
agrees to contribute to the amount paid or payable by such indemnified party as
a result of such loss, claim, damage, liability or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and the Indemnified Person on the other hand in connection with the
statements or omissions which resulted in such Claim, as well as any other
relevant equitable considerations. The relative fault of the indemnifying party
and the Indemnified Person shall be determined by reference to, among other
things, whether the untrue statement of a material fact or the omission to state
a material fact on which such Claim is based relates to information supplied by
the indemnifying party or by the Indemnified Person, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. Notwithstanding the forgoing, (a) no contribution
shall be made under circumstances where the payor would not have been liable for
indemnification under the fault standards set forth in Section 6, (b) no seller
of Registrable Securities guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
such fraudulent misrepresentation and (c) contribution by any seller of
Registrable Securities shall be limited in amount to the net proceeds received
by such seller from the sale of such Registrable Securities.

                                      9

<PAGE>

The Company and the Purchasers agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by PRO RATA
allocation (even if the Purchasers and any other party were treated as one
entity for such purpose) or by any other method of allocation that does not
take account of the equitable considerations referred to in this Section.

      8. REPORTS UNDER EXCHANGE ACT. With a view to making available to the
Purchasers the benefits of Rule 144 promulgated under the Securities Act or any
other similar 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 ("Rule 144"), the Company agrees to:

                  (a)   make and keep public information  available,  as those
terms are understood and defined in Rule 144;

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

                  (c) furnish to each Purchaser so long as such Purchaser owns
Registrable Securities, Debentures or Warrants promptly upon request, (i) a
written statement by the Company that it has complied with the reporting
requirements of the Securities Act and the Exchange Act, (ii) a copy of the most
recent annual or periodic report of the Company and such other reports and
documents so filed by the Company and (iii) such other information as may be
reasonably requested to permit the Purchaser to sell such securities pursuant to
Rule 144 without registration.

      9. ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by a Purchaser to any transferee of all or any portion of
the principal amount of Debentures or the Warrants, or the underlying Common

EXHIBIT 4.5

                            JUNIOR SECURITY AGREEMENT

            JUNIOR SECURITY AGREEMENT (this "Agreement"), dated as of June
11, 2001, between FLOUR CITY INTERNATIONAL, INC., a Nevada corporation whose
address is 1044 Fordtown Road, Kingsport, TN 37663 (the "Debtor"), and
DIMENSIONAL PARTNERS, L.P. and DIMENSIONAL PARTNERS, LTD. (together with any
permitted assigns of the Debentures, the "Secured Parties").

                                   WITNESSETH:

            WHEREAS, the Debtor has issued to the Secured Parties its 8 1/2%
Subordinated Secured Convertible Debentures Due 2004 of even date herewith in
the aggregate principal amount of $2,500,000 (the "Debentures"); and

            WHEREAS, in order to induce the Secured Parties to purchase the
Debentures and to secure the Debtor's performance and payment under the
Debentures, the Debtor has agreed to execute this Agreement.

            NOW THEREFORE, the parties hereto agree as follows:

            1. SECURITY INTEREST. As collateral security for the prompt and
complete payment and performance when due of its obligations under the
Debentures and the prompt performance and observance of all the covenants
contained therein and in this Agreement, the Debtor hereby grants to the Secured
Parties a continuing security interest in and lien on all of the Debtor's right,
title and interest in, to and under all of the Collateral (as defined below),
including all accessions to the Collateral, substitutions and replacements
thereof, now owned or existing and hereafter acquired, created or arising, and
all products and proceeds thereof (including, without limitation, claims of the
Debtor against third parties with respect to any Collateral). The "Collateral"
shall consist of all accounts, receivables, accounts receivable, book debts and
rights to payment no matter how evidenced, and other obligations of any kind,
now or hereafter existing, arising out of or in connection with the sale or
lease of goods or the rendering of services by the Debtor or any of its
subsidiaries in the United States; and all proceeds of every kind and nature,
including proceeds of proceeds, of any and all of the foregoing Collateral,
including money and cash.

            2.  REPRESENTATIONS AND WARRANTIES.  The Debtor hereby represents
and warrants that:

            (a) Except for the security interest granted pursuant to this
Agreement and as set forth on Schedule A hereto, the Debtor is the sole owner of
the Collateral, having good and valid title thereto, free and clear of any and
all liens and encumbrances.

<PAGE>

            (b) The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby to be performed by the
Debtor have been duly and validly authorized by the Board of Directors of the
Debtor and no other corporate proceedings on the part of the Debtor are
necessary to authorize this Agreement or to consummate the transactions so
contemplated. The Debtor has all corporate power and authority to execute and
deliver this Agreement, to consummate the transactions hereby contemplated and
to take all other actions required to be taken by it pursuant to the provisions
hereof; and this Agreement is the legal, valid and binding obligation of the
Debtor, enforceable against the Debtor in accordance with its terms.

            (c) Except for the filing of UCC-1 financing statements in order to
perfect the security interest granted hereunder, no consent, approval,
authorization or notification of, or declaration, filing or registration with,
any governmental entity is required on behalf of or on the part of the Debtor in
connection with the execution, delivery, or performance of this Agreement and
the consummation of the transactions contemplated hereby by the Debtor. Neither
the execution and delivery of this Agreement by the Debtor nor the consummation
of the transactions hereby contemplated to be performed by the Debtor will (i)
constitute any violation or breach of the Articles of Incorporation or By-Laws
of the Debtor, (ii) violate, or constitute a default under, or permit the
termination or acceleration of the maturity of, any indebtedness for borrowed
money of the Debtor, (iii) violate, or constitute a default under, or permit the
termination of, any license, contract, lease or other instrument to which the
Debtor is a party or by which the Debtor or any of its properties is subject or
by which any of them is bound, or (iv) violate any order, writ, injunction,
decree, statute, rule or regulation, governmental license or permit, to which
the Debtor or any of its properties is subject or by which any of them is bound.

            (d) The Debtor is a corporation duly organized, validly existing and
in good standing under the laws of the State of Nevada.

            (e) The address set forth at the beginning of this Agreement is the
Debtor's chief executive office. All books and records of the Debtor and its
subsidiaries with regard to the Collateral are maintained and kept at such
address of the Debtor set forth at the beginning of this Agreement.

            3.  COVENANTS.  The Debtor hereby covenants as follows:

            (a) The Debtor shall pay all reasonable expenses and reimburse the
Secured Parties for any reasonable expenditure, including reasonable attorneys'
and accountants' fees, including attorneys' fees incurred in any appellate or
insolvency proceedings, in connection with the Secured Parties' exercise of
their rights and remedies herein or contained in the Debentures.

            (b) The Debtor shall execute and deliver, or cause to be executed
and delivered, to the Secured Parties those documents and agreements, including
without limitation, Uniform Commercial Code financing statements, and shall take
or cause to be taken those actions that the Secured Parties may, from time to
time, reasonably request to carry out the terms and conditions of this Agreement
and the Debentures.

                                       2

<PAGE>

            (c) Except for liens or other charges or encumbrances securing the
Senior Debt (as defined in the Debentures), including the other security
interests, liens and encumbrances listed on Exhibit A hereto (collectively, the
"Permitted Senior Liens"), and liens made in the ordinary course of business and
not securing indebtedness for borrowed money, including landlord liens, tax
liens (provided they secure sums being contested in good faith), liens created
under contracts of suretyship entered into in the ordinary course of business
and the like (together with the Permitted Senior Liens, the "Permitted Liens")
the Debtor has not, and hereafter shall not, assign, convey, sell, mortgage,
pledge, hypothecate, transfer, encumber or otherwise dispose of, or grant a
security interest in, the Collateral or any interest therein, without the prior
written consent of the Secured Parties.

            (d) The Debtor will not change its name, identity or organizational
structure in any manner which might make any financing or continuation statement
filed in connection herewith seriously misleading within the meaning of Section
9-402(7) of the New York Uniform Commercial Code (the "UCC"), or any other then
applicable provision of the UCC (as it may be amended or revised from time to
time) unless the Debtor shall have taken all action necessary or reasonably
requested by the Secured Party to amend such financing statement or continuation
statement so that it is not seriously misleading. The Debtor will not change its
principal place of business, remove its records from such place or change its
state of incorporation unless the Debtor shall have given the Secured Party at
least 30 days' prior written notice thereof and shall have taken such action as
is necessary to cause the security interest of the Secured Parties in the
Collateral to continue to be perfected. The Collateral shall not be located at
any location except as is specified in Section 2(e) hereof without the prior
written consent of the Secured Party.

            (e) Provided the Secured Parties maintain the confidentiality
thereof and do not use any such information in violation of any laws (including
securities laws), the Debtor agrees to furnish to the Secured Parties, from time
to time on reasonable advance written notice, such information relating to the
Collateral as the Secured Parties may reasonably request.

            (f) Prior to or concurrently with the execution and delivery of this
Agreement (and thereafter as may reasonably be required), the Debtor shall file
such financing statements and other documents in such offices as the Secured
Parties may request to perfect the security interests granted by Section 1 of
this Agreement.

            4. CONTINUING SECURITY INTEREST. This Agreement shall create a
continuing security interest in the Collateral securing the Debtor's obligations
under the Debentures and shall (a) remain in full force and effect until the
payment and discharge in full of the Debtor's obligations under and pursuant to
the terms of the Debentures, (b) be binding upon the Debtor and its successors
and assigns and (c) inure to the benefit of the Secured Parties and their
successors, transferees and assigns. Upon the termination of the security
interest created hereby pursuant to clause (a) above, the Secured Parties shall,
at the Debtor's request and expense, deliver to the Debtor a release of all
security interests granted by the Debtor to such Secured Party pursuant to this
Agreement.

            5. REALIZATION UPON COLLATERAL. In the event an "event of default"
shall occur under the terms of the Debentures (an "Event of Default"), the
Secured Parties shall, subject to the terms of this Agreement and the Securities
Purchase Agreement of even date herewith (the

                                       3

<PAGE>

"Purchase Agreement"), have all of the rights of a secured party under the
Uniform Commercial Code as in effect in the State of New York, including,
without limitation, the right to sell the Collateral at public or private
sale for cash or credit and on such terms as the Secured Parties deem
reasonable. The Secured Parties shall apply the proceeds of any realization
on the whole or any part of the Collateral after deducting all of their
reasonable expenses and costs incurred in collection and realization
(including, without limitation, reasonable counsel's fees and expenses) to
the payment of the Debtor's obligations to the Secured Parties under the
Debentures; the balance, if any, of such proceeds shall be paid to Debtor.

            6.  THE SECURED PARTIES' APPOINTMENT AS ATTORNEY-IN-FACT.

            (a) The Debtor hereby irrevocably constitutes and appoints each of
the Secured Parties and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of the Debtor and in the name of the
Debtor or in its own name, from time to time in the Secured Parties' discretion,
for the purpose of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute and deliver any and all documents and
instruments which may be reasonably necessary or desirable to exercise the
Secured Parties' rights with respect to the Collateral, subject to the terms of
this Agreement and applicable law.

            (b) The Secured Parties agree that, except upon the occurrence and
during the continuation of an Event of Default and until any necessary consents
have been obtained, they will forbear from exercising the power of attorney or
any rights granted to the Secured Parties pursuant to this Section 6. The Debtor
hereby ratifies, to the extent permitted by law, all that said attorney shall
lawfully do or cause to be done by virtue hereof. The power of attorney granted
pursuant to this Section 6 is a power coupled with an interest and shall be
irrevocable until the Debentures are paid in full.

            (c) The powers conferred on the Secured Parties hereunder are solely
to protect the Secured Parties' interests in the Collateral and shall not impose
any duty upon them to exercise any such powers. The Secured Parties shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers and neither the Secured Parties nor any of their
officers, directors, employees or agents shall be responsible to the Debtor for
any act or failure to act, except for their own gross negligence or willful
misconduct.

            7. SEVERABILITY AND ENFORCEABILITY. If any of the provisions of this
Agreement, or the application thereof to any person or circumstance shall, to
any extent, be invalid or unenforceable, the remainder of this Agreement, or the
application of such provision or provisions to persons or circumstances other
than those to whom or which it is held invalid or unenforceable, shall not be
affected thereby and every provision of this Agreement shall be valid and
enforceable to the fullest extent permitted by law.

            8. GOVERNING LAW; SEVERABILITY. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, without
giving effect to principles of conflicts of law (other than Section 5-1401 and
Section 5-1402 of the New York General Obligations Law). Any action or
proceedings to enforce or arising out of this Agreement may be commenced in any
jurisdiction of the federal courts whose districts

                                       4

<PAGE>

encompass any part of the City of New York or the state courts of the State
of New York sitting in the City of New York. Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

            9. NOTICES. (a) All notices or other communications to be given
