ATTN: CARLOS PINTO

Dear Mr. Pinto:

         We have acted as counsel to HomeCom Communications, Inc., a Delaware
corporation (the "COMPANY"), in connection with the Securities Purchase
Agreement, dated as of April 14, 2000, between the holders listed in Exhibit
"A," attached hereto (the "Holders") and the Company (the "AGREEMENT") and the
transactions contemplated therein including, without limitation, the issuance of
the Series E Convertible Preferred Stock (the "SERIES E SHARES").

         In so acting, we have examined the Agreement, the Certificate of
Designations, Preferences and Rights With respect to the Series E Shares (the
"CERTIFICATE OF DESIGNATIONS"), the Irrevocable Transfer Agent Instructions (the
"TRANSACTION AGREEMENTS") and the Company's Certificate of Incorporation, as in
effect on the date hereof, and we have examined and considered such corporate
records, certificates and matters of law as we have deemed appropriate as a
basis for our opinions set forth below.

         Based upon the foregoing and subject to the assumptions, limitations,
qualifications and exceptions stated herein, we are of the opinion that as of
the date hereof.

         (1) Upon conversion of the Series E Preferred Shares in accordance with
the terms of the Certificate of Designation, the shares of the Company's common
stock to be issued to the holders thereof (the "CONVERSION SHARES") will be
validly issued, fully paid and non-assessable, and free from all taxes, liens
and charges with respect to the issue thereof.

                                      1

<PAGE>

         (2) Based upon the representations, warranties and covenants set forth
in the Agreement, Conversion Shares may be issued to the Holders without
registration under the Securities Act of 1933, as amended.

         (3) The certificates for the Conversion Shares should bear the
following legend:

                 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                 REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                 APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
                 OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE
                 OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
                 THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
                 SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN A REASONABLY
                 ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID
                 ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT
                 TO RULE 144 UNDER THE ACT.

         These opinions are limited to the matters expressly stated herein and
are rendered solely your benefit and may not be quoted or relied upon for any
other purpose or by an other person.

         The opinions expressed herein are subject to the following assumptions,
limitations, qualifications and exceptions:

                           (a) We have assumed the genuineness of all
                 signatures, the authenticity of all Transaction Agreements
                 submitted to us as originals, the conformity with originals of
                 all Transaction Agreements submitted to us as copies, the
                 authenticity of certificates of public officials and the due
                 authorization, execution and delivery of all Transaction
                 Agreements (except the due authorization, execution and
                 delivery by the Company of the Transaction Agreements).

                           (b) We have assumed that the Holders each have the
                 legal right, capacity and power to enter into, enforce and
                 perform all of its obligations under the Transaction
                 Agreements. Furthermore, we have assumed the due authorization
                 by the Holders of all requisite action and the due execution
                 and delivery of the Transaction Agreements by the Holders, and
                 that the Transaction Agreements are valid and binding upon the
                 Holders and are enforceable against the

                                      2

Holders in accordance with their terms.

         Our examination of law relevant to the matters covered by this opinion
is limited to the laws of the State of Georgia, the Corporate Law of the State
of Delaware and the federal United States law specifically referred to herein,
and we express no opinion as to the effect on the matters covered by this
opinion of the laws of any other jurisdiction.

         This opinion in given as of the date hereof and we assume no
obligation, to update or supplement this opinion to reflect any facts or
circumstances which may hereafter come to our attention or any changes in laws
which may hereafter occur.

                                            Very truly yours,

                              WARRANT AGREEMENT

         WARRANT AGREEMENT dated as of April 14, 2000, between HomeCom
Communications, Inc., a Delaware corporation (the "COMPANY"), and McNab LLC, a
limited liability company (hereinafter referred to as "INVESTOR").

                             W I T N E S S E T H:

         WHEREAS, Investor has participated as an Investor in connection with
the Company's offering (the "OFFERING") of up to $2,000,000 in principal amount
of Series E Preferred Stock (the "PREFERRED STOCK") for an aggregate purchase
price $2,000,000; and

         WHEREAS, the Warrants issued pursuant to this Agreement are being
issued by the Company to Investor and/or its designees, in consideration for,
and as part of the investment by Investor in connection with the Offering;

         NOW, THEREFORE, in consideration of the premises, the agreements herein
set forth and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

         1.       GRANT.

         Investor and/or its designees are hereby granted the right to purchase,
at any time from the date of issuance of the aforementioned Preferred Stock
until 5:00 P.M., Eastern Standard Time, on April 14, 2005 (the "WARRANT EXERCISE
TERM"), 33,334 Shares at an exercise price (subject to adjustment as provided in
Article 7 hereof) of $3.35 per share (the "INITIAL EXERCISE PRICE").

         2.       WARRANT CERTIFICATES.

         The warrant certificates (the "WARRANT CERTIFICATES") delivered and to
be delivered pursuant to this Agreement shall be in the form set forth as
EXHIBIT A, attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as required or
permitted by this Agreement.

         3.       EXERCISE OF WARRANTS.

                  3.1 CASH EXERCISE. The Exercise Price may be paid in cash or
by check to the order of the Company, or any combination of cash or check,
subject to adjustment as provided in Article 7 hereof. Upon surrender of the
Warrant Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Exercise Price (as hereinafter defined) for the
Shares purchased, at the Company's

                                      1

<PAGE>

executive offices currently located at Fourteen Piedmont Center, Suite 100,
3535 Piedmont Road, Atlanta, Georgia 30305, the registered holder of a
Warrant Certificate ("HOLDER" or "HOLDERS") shall be entitled to receive a
certificate or certificates for the Shares so purchased. The purchase rights
represented by each Warrant Certificate are exercisable at the option of the
Holder hereof, in whole or in part (but not as to fractional shares of the
Common Stock). In the case of the purchase of less than all the Shares
purchasable under any Warrant Certificate, the Company shall cancel said
Warrant Certificate upon the surrender thereof and shall execute and deliver
a new Warrant Certificate of like tenor for the balance of the Shares
purchasable thereunder.

                  3.2 CASHLESS EXERCISE. At any time during the Warrant Exercise
Term, the Holder may, at its option, exchange this Warrant, in whole or in part
(a "WARRANT EXCHANGE"), into the number of Shares determined in accordance with
this Section 3.2, by surrendering this Warrant at the principal office of the
company or at the office of its transfer agent, accompanied by a notice stating
such Holder's intent to effect such exchange, the number of Shares to be
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "NOTICE OF EXCHANGE"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "EXCHANGE DATE"). Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new warrant of
like tenor evidencing the balance of the Shares remaining subject to this
Warrant, shall be issued as of the Exchange Date and delivered to the Holder
within seven (7) business days following the Exchange Date. In connection with
any Warrant Exchange, this Warrant shall represent the right to subscribe for
and acquire the number of Shares (rounded to the next highest integer) equal to
(i) the number of Shares specified by the Holder in its Notice of Exchange (the
"TOTAL NUMBER") less (ii) the number of Shares equal to the quotient obtained by
dividing (A) the product of the Total Number and the then existing Exercise
Price by (B) the current market value of a share of Common Stock.

         4.       ISSUANCE OF CERTIFICATES.

         Upon the exercise of the Warrants, the issuance of certificates for the
Shares shall be made forthwith (and in any event within five business days
thereafter) without charge to the Holder thereof including, without limitation,
any tax which may be payable in respect of the issuance thereof, and such
certificates shall be issued in the name of, or in such names as may be directed
by, the Holder thereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect of any transfer involved
in the issuance and delivery of any such certificates in a name other than that
of the Holder and the Company shall not be required to issue or deliver such
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to satisfaction of the Company that such tax has been paid.

         The Warrant Certificates and the certificates representing the Shares
shall be executed on behalf of the Company by the manual or facsimile signature
of the present

                                      2

<PAGE>

or any future Chairman or Vice Chairman of the Board of Directors, Chief
Executive officer or President or Vice President of the Company under its
corporate seal reproduced thereon, attested to by the manual or facsimile
signature of the present or any future Secretary or Assistant Secretary of
the Company. Warrant Certificates shall be dated the date of execution by the
Company upon initial issuance, division, exchange, substitution or transfer.

                                      3

<PAGE>

         The Warrant Certificates and, upon exercise of the Warrants, in part or
in whole, certificates representing the Shares shall bear a legend substantially
similar to the following:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT
         BE OFFERED OR SOLD EXCEPT (I) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE ACT, (II) TO THE EXTENT APPLICABLE, PURSUANT TO
         RULE 144 UNDER THE ACT (OR ANY SIMILAR RULE UNDER SUCH ACT RELATING TO
         THE DISPOSITION OF SECURITIES), OR (III) UPON THE DELIVERY BY THE
         HOLDER TO THE COMPANY OF AN OPINION OF COUNSEL, REASONABLY SATISFACTORY
         TO COUNSEL TO THE ISSUER, STATING THAT AN EXEMPTION FROM REGISTRATION
         UNDER SUCH ACT IS AVAILABLE.

         5.       PRICE.

                  5.1 ADJUSTED EXERCISE PRICE. The adjusted Exercise Price shall
be the price which shall result from time to time from any and all adjustments
of the Initial Exercise Price in accordance with the provisions of Article 7
hereof.

                  5.2 EXERCISE PRICE. The term "EXERCISE PRICE" herein shall
mean the Initial Exercise Price or the adjusted Exercise Price, depending upon
the context.

         6.       REGISTRATION RIGHTS.

                  6.1 REGISTRATION UNDER THE SECURITIES ACT OF 1993.

The Warrants and the Shares have not been registered for purposes of public
distribution under the Securities Act of 1933, as amended ("THE ACT").

                  6.2 REGISTRABLE SECURITIES. As used herein the term
"REGISTRABLE SECURITY" means each of the Warrants, the Shares and any shares
of Common Stock issued upon any stock split or stock dividend in respect of
such Shares; provided, however, that with respect to any particular
Registrable Security, such security shall cease to be a Registrable Security
when, as of the date of determination, (i) it has been effectively registered
under the Securities Act and disposed of pursuant thereto, (ii) registration
under the Securities Act is no longer required for the immediate public
distribution of such security or (iii) it has ceased to be outstanding. The
term "REGISTRABLE SECURITIES" means any and/or all of the securities falling
within the foregoing definition of a "Registrable Security." In the event of
any merger, reorganization, consolidation, recapitalization or other change
in corporate structure affecting the Common Stock, such adjustment shall be
made in the definition of

                                      4

<PAGE>

"Registrable Security" as is appropriate in order to prevent any dilution
or enlargement of the rights granted pursuant to this Article 6.

                  6.3 PIGGYBACK REGISTRATION. If, at any time during the five
years following the date of this Agreement, the Company proposes to prepare and
file any registration statement or post-effective amendments thereto covering
equity or debt securities of the Company, or any such securities of the Company
held by its shareholders (in any such case, other than in connection with a
merger, acquisition or pursuant to Form S-8 or successor form), (for purposes of
this Article 6, collectively, a "REGISTRATION STATEMENT"), it will give written
notice of its intention to do so by registered mail ("NOTICE"), at ten (10)
business days prior to the filing of each such Registration Statement, to all
holders of the Registrable Securities. Upon the written request of such a holder
(a "REQUESTING HOLDER"), made within ten (10) business days after receipt of the
Notice, that the Company include any of the Requesting Holder's Registrable
Securities in the proposed Registration Statement, the Company shall, as to each
such Requesting Holder, use its best efforts to effect the registration under
the Securities Act of the Registrable Securities which it has been so requested
to register ("PIGGYBACK REGISTRATION"), at the Company's sole cost and expense
and at no cost or expense to the Requesting Holders. Notwithstanding the
provisions of this Section 6.3, the Company shall have the right at any time
after it shall have given written notice pursuant to this Section 6.3
(irrespective of whether any written request for inclusion of such securities
shall have already been made) to elect not to file any such proposed
Registration Statement, or to withdraw the same after the filing but prior to
the effective date thereof.

         7.       ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SHARES.

                  7.1 SUBDIVISION AND COMBINATION. In case the Company shall at
any time subdivide or combine the outstanding shares of Common Stock, the
Exercise Price shall forthwith be proportionately decreased in the case of
subdivision or increased in the case of combination.

                  7.2 ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of
the Exercise Price pursuant to the provisions of this Article 7, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of Shares issuable upon
exercise of the Warrants immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

                  7.3 RECLASSIFICATION, CONSOLIDATION, MERGER, ETC. In case of
any reclassification or change of the outstanding shares of Common Stock (other
than a change in par value to no par value, or from no par value to par value,
or as a result of a subdivision or combination), or in the case of any
consolidation of the Company with, or merger of the Company into, another
corporation (other than a consolidation or merger in which the Company is the
surviving corporation and which does not result in any

                                      5

<PAGE>

reclassification or change of the outstanding shares of Common Stock, except
a change as a result of a subdivision or combination of such shares or a
change in par value, as aforesaid), or in the case of a sale or conveyance to
another corporation of the property of the Company as an entirety, the
Holders shall thereafter have the right to purchase the kind and number of
shares of stock and other securities and property receivable upon such
reclassification, change, consolidation, merger, sale or conveyance as if the
Holders were the owners of the shares of Common Stock underlying the Warrants
immediately prior to any such events at a price equal to the product of (x)
the number of shares issuable upon exercise of the Warrants and (y) the
Exercise Price in effect immediately prior to the record date for such
reclassification, change, consolidation, merger, sale or conveyance as if
such Holders had exercised the Warrants.

                  7.4 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES. No
adjustment of the Exercise Price shall be made:

                           (a) Upon the issuance or sale of shares of Common
                   Stock upon the exercise of the Warrants; or

                           (b) Upon (i) the issuance of options pursuant to the
                  Company's employee stock option plan in effect on the date
                  hereof or the issuance or sale by the Company of any shares of
                  Common Stock pursuant to the exercise of any such options, or
                  (ii) the issuance or sale by the Company of any shares of
                  Common Stock pursuant to the exercise of any options or
                  warrants previously issued and outstanding on the date hereof;
                  or

                           (c) Upon the issuance of shares of Common Stock
                  pursuant to contractual obligations existing on the date
                  hereof; or

                           (d) If the amount of said adjustment shall be less
                  than 2 cents (2(cent)) per Share, provided, however, that in
                  such case any adjustment that would otherwise be required then
                  to be made shall be carried forward and shall be made at the
                  time of and together with the next subsequent adjustment
                  which, together with any adjustment so carried forward, shall
                  amount to at least 2 cents (2(cent)) per Share.

                  7.5 DIVIDENDS AND OTHER DISTRIBUTIONS WITH RESPECT TO
OUTSTANDING SECURITIES. In the event that the Company shall at any time prior to
the exercise of all Warrants declare a dividend (other than a dividend
consisting solely of shares of Common Stock or a cash dividend or distribution
payable out of current or retained earnings) or otherwise distribute to its
shareholders any monies, assets, property, rights, evidences of indebtedness,
securities (other than shares of Common Stock), whether issued by the Company or
by another person or entity, or any other thing of value, the Holder or Holders
of the unexercised Warrants shall thereafter be entitled, in addition to the
shares of Common Stock or other securities receivable upon the exercise thereof,
to receive, upon the exercise of such Warrants, the same monies, property,
assets, rights, evidences of indebtedness, securities or any other thing of

                                      6

<PAGE>

value that they would have been entitled to receive at the time of such dividend
or distribution. At the time of any such dividend or distribution, the Company
shall make appropriate reserves to ensure the timely performance of the
provisions of this Subsection 7.5.

         8.       EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

         Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.
         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

         9.       ELIMINATION OF FRACTIONAL INTERESTS.

         The Company shall not be required to issue certificates representing
fractions of shares of Common Stock and shall not be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock.

         10.      RESERVATION AND LISTING OF SECURITIES.

         The Company shall at all times reserve and keep available out of its
authorized shares of Common Stock, solely for the purpose of issuance upon the
exercise of the Warrants, such number of shares of Common Stock as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock issuable upon such exercise shall be duly and validly issued,
fully paid, nonassessable and not subject to the preemptive rights of any
shareholder. As long as the Warrants shall be outstanding, the Company shall use
its best efforts to cause all shares of Common Stock issuable upon the exercise
of the Warrants to be listed on or quoted on the electronic bulletin board, by
NASDAQ or listed on such national securities exchanges.

         11.      NOTICES TO WARRANT HOLDERS.

         Nothing contained in this Agreement shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive notice
as a shareholder in respect of any meetings of shareholders for the election of
directors or any other matter,

                                      7

<PAGE>

or as having any rights whatsoever as a shareholder of the Company. If,
however, at any time prior to the expiration of the Warrants and their
exercise, any of the following events shall occur:

                  (a) the Company shall take a record of the holders of its
         shares of Common Stock for the purpose of entitling them to receive a
         dividend or distribution payable otherwise than in cash, or a cash
         dividend or distribution payable otherwise than out of current or
         retained earnings, as indicated by the accounting treatment of such
         dividend or distribution on the books of the Company; or

                  (b) a dissolution, liquidation or winding up of the Company
