     (c)     Benefits.   Employee shall receive a bonus in the amount of Fifty
Thousand Dollars ($50,000) for services rendered to Employer during calendar
year 1997, which bonus shall be payable on or before April 1, 1998.   The
bonus shall be deemed to be earned if Employee is employed by Employer on
December 31, 1997.  From time to time during the Employment Term, Employer may
award Employee such other bonuses, if any, as Employer deems appropriate, in
its sole discretion.  Employee shall be entitled to participate in all pension

     (d)     Vacations.  Employee shall be entitled to vacations in accordance
with Employer's personnel policies in effect from time to time.

     4.     Other Activities.  During the Employment Term, Employee shall
devote  substantially all of his working time and efforts to the business and
affairs of Employer and to the duties and responsibilities assigned to him
pursuant to this Agreement.  Employee may devote a reasonable amount of his
time to civic, community or charitable activities.  Subject to the
restrictions contained in paragraph 6 hereof, Employee may invest his assets
in such manner as will not require any substantial services by Employee in the
conduct of the business or affairs of the entities or in the management of the
assets in which such investments are made.  Employee shall fully inform
Employer of all such businesses and managements in which Employee actively
engages during the Employment Term.

     5.     Intellectual Property and Confidential Information.

     (a)     Intellectual Property.  During the Employment Term, Employee will
disclose to Employer all ideas, inventions and business plans developed by him
during such period which relate directly or indirectly to the business of
Employer, including without limitation any process, operation, product or
improvement which may be patentable or unpatentable, copyrightable or not
copyrightable (collectively, "Intellectual Property").  Employee agrees that
such will be the property of Employer and that he will at Employer's request
and cost do whatever is necessary to secure the rights thereto by patent,
copyright or otherwise to Employer.

     (b)     Confidential Information.  In the course of Employee's
employment, Employee will be provided with or may create certain information,
technical data and know-how regarding the business of Employer, its customers,
pricing, cost of goods, plans and its products, including, but not limited to,
information relating to Employer's existing or contemplated businesses,
employees, vendors, customer identity and

                                       2
<PAGE>

requirements, customer lists, business plans, sales, financials, products
(quantities, vendor and customer prices, profit margins, discounts, rebates,
refunds and credits), technology, manufacturing techniques, engineering
processes, product formulae, marketing and promotion plans and methods,
technical service expertise and distribution activities, all of which is
confidential (such information, together with the Intellectual Property is
hereinafter referred to as "Confidential Information").  Employee shall
receive, hold and treat all Confidential Information as confidential and
secret and shall protect the secrecy of said Confidential Information.
Employee shall disclose the Confidential Information only to such persons who
are required to have such knowledge in connection with their work for
Employer.  Such Confidential Information shall not be disclosed to others
without the prior written consent of the Employer. The following shall not be
Confidential Information and the provisions of this subparagraphs shall not be
applicable to:  (i) information which at the time of disclosure to Employee is
a matter of public knowledge; (ii) information which, after disclosure,
becomes public knowledge other than through a breach of the Agreement, any
other confidentiality or trade-secret agreement or violation of any trade
secret or confidential relationships between Employer and any third party; and
(iii) information which Employee reasonably determines may be necessary or
appropriate to disclose in order to effectively discharge his duties to
Employer.  Employee shall not use such Confidential Information for his own
use or for the use of anyone other than Employer.  At such time as Employee
shall cease to be employed by the Employer, the Employee will surrender to the
Employer all papers, documents, writings, computer disks, photographs, and
other property provided by him or coming into his possession by or through
Employee's employment and relating to the Confidential Information (including
all copies and reproductions thereof), and Employee agrees that all such
Confidential Information and the materials containing such Confidential
Information will at all times remain the property of the Employer.  Employee
shall return to Employer either before or immediately upon the Employee's
termination of employment with Employer any and all written information,
materials, or equipment (including computer disks) and any other documents,
equipment, and materials of any other kind relating in any way to Employer's
business in Employee's possession, custody, or control, whether confidential
or not, including any and all copies or reproductions thereof which may have
been made by or for Employee.

     Employee understands and agrees that in the event Employee is in doubt,
or should reasonably be in doubt, regarding whether or not certain information
is Intellectual Property or Confidential Information, Employee shall obtain
the written approval of Employer's Board of Directors prior to any
disclosure.  In the event Employee's employment has been terminated, Employee
shall obtain the written approval of Employer's general counsel (as designated
by Employers's Board of Directors) prior to any disclosure if Employee is or
should be in such doubt.  A failure to obtain consent in a case where Employee
is or should be in doubt regarding the nature of the information

                                       3
<PAGE>

without obtaining prior approval shall constitute a breach of this Agreement.

     6.     Termination.

     (a)     Termination for Cause.  Employer shall have the right at any
time, by written notice to Employee, to terminate the Employment Term
forthwith and to discharge Employee for cause if any one of the following
events shall occur during the Employment Term:

             (i)     Employee's conviction in a court of law of a felony, or
        of any crime or offense involving misuse or misappropriation of money
        or other property; or

             (ii)    Employee's continued, repeated failure or refusal to
        perform specific directives of the Board of Directors of Employer,
        which directives are consistent with the scope and nature of
        Employee's duties and responsibilities, and which are not remedied by
        Employee within ten (10) days after notice; or

            (iii)    The commission of any intentional tort by Employee
        against Employer, Employer's other employees or Employer's customers,
        or arising in connection with Employee's duties and responsibilities
        hereunder; or

             (iv)    A breach by Employee of any of the covenants set forth in
        paragraph 5 hereof; or the repeated breach by Employee of any term,
        condition or provision of any employee manual, memorandum, notice or
        other instruction as may be provided by Employer to its employees from
        time to time; or the repeated breach by Employee of any other material
        term of this Agreement; or

              (v)    Any act of dishonesty by Employee which adversely affects
        the business of Employer; or

             (vi)    Employee's termination of his employment with Employer
        prior to the end of the Employment Term.

        In the event of termination for cause as set forth in this paragraph
        6(a), or upon violation of any of the obligations and restrictive
        covenants set forth in paragraph 5 hereof, whether before or after
        termination of employment, Employee shall have no further rights under
        this Agreement of any kind. Nothing herein shall be deemed to limit
        any other rights and remedies Employer may have against Employee.

     (b)     Termination for Death.  In the event of the death of Employee,
the Employment Term shall thereupon terminate and be of no further force or
effect.

     (c)     Termination for Disability.  In the event that, by reason of
physical or mental illness continuing for a period of twelve (12) consecutive
weeks in any consecutive twelve (12) month period, Employee has been
substantially unable, with reasonable accommodation, to perform the essential
functions of the Director of Acquisitions,

                                       4
<PAGE>

Employer may, on ten (10) days prior written notice to Employee, terminate the
Employment Term.  Employee's obligations under paragraph 5 shall survive the
Termination for Disability.

     (d)     Termination Without Cause.  Employer or Employee may terminate
the Employment Term at any time without cause by giving the other party notice
in writing at least thirty (30) days prior to the effective date of Employee's
termination.

     (e)     Severance Pay.  In the event (i) the Initial Employment Term
expires and is not renewed by Employer or (ii) Employer terminates the Initial
Employment Term without cause or (iii) there is a Change of Control of
Employer (which is defined as 51% or more of the capital stock of Employer is
held by any person or entity other than Kenneth A. Hendricks or Diane M.
Hendricks) and Employee elects in writing to terminate this Agreement within
sixty (60) days of the effective date of the Change of Control, then Employer
shall pay Employee an amount equal to his then current base salary for one
year ("Severance Pay"), which sum shall be payable on the effective date of
termination of Employee's employment.  Employee's obligations under paragraph
5 and 7 shall survive the termination without cause (whether employment is
terminated by Employer or Employee); provided, however, Employee's obligations
under Paragraph 7(b) shall not survive if (i) the Initial Employment Term
expires and is not renewed by Employer or (ii) Employee terminates the Initial
Employment Term pursuant to paragraph 6(d) due to a Change of Control.

     7.     Restrictive Covenants.

     (a)     Covenant Not To Compete During Employment Term.  During the
Employment Term (as renewed), Employee shall not directly or indirectly
finance, own, manage, operate, control, or participate in the financing,
ownership, management, operation or control of, or be employed by or act as an
officer, director, agent, representative, advisor, consultant, partner or
investor, or be connected with in any other manner, any business of the type
and character engaged in or competitive with that conducted by Employer.  For
these purposes, Employee's ownership of securities of a public company not in
excess of one percent (1%) of any class of such securities shall not be
considered to be in competition with Employer.

     (b)     Covenant Not to Compete After Employment.  Employee agrees that,
for a period beginning at the end of the Initial Employment Term or the
earlier termination thereof for any reason and ending one (1) calendar year
from the effective of such expiration or termination ("Non-Compete Period"),
Employee will not directly or indirectly in any place within the United States
("Non-Compete Area") finance, own, manage, advise, consult, operate, control,
or participate in the financing, ownership,

                                       5
<PAGE>

management, consultation, operation or control of, or be employed by or act as
an officer, director, agent, representative, advisor, consultant, partner or
investor, or be connected in any manner with any business which engages in the
distribution of roofing or siding products to contractors or which offers
advice regarding mergers, acquisitions and finance to any business engaged in
the distribution of roofing or siding products to contractors (together
"Competing Business"). During the Non-Compete Period, Employee will not employ
or attempt to employ any individual then employed by Employer during the
Non-Compete Period.  In consideration for Employee's covenants and obligations
under this paragraph 7, Employer agrees to employ Employee and pay Employee
the base salary, and the Severance Pay if the conditions set forth in
paragraph 7(e) are fulfilled.  In the event of a Change of Control, Employee
may terminate the covenants contained in this paragraph 7(b) if (i) Employee
gives written notice of his election to Employer within ten (10) days of the
Change of Control and (ii) Employees waives his rights to Severance Pay and
returns any Severance Pay received.

     (c)     Other Covenants.  In view of the fact that the services to be
rendered by Employee on behalf of Employer are of a special and unique
character, Employee agrees that while he is employed by Employer and during
the Non-Compete Period, he shall not, directly or indirectly, either on his
own behalf or on behalf of any other person, firm, partnership, corporation,
limited liability company or other entity, without the prior written consent
of Employer:

              (i)     Attempt in any manner to persuade any client of Employer
        to cease to do business or to reduce the amount of business which any
        client has customarily done or contemplates doing with Employer; or

             (ii)     Employ or attempt to employ any person who is then in
        Employer's employment or was in Employer's employment within ninety
        (90) days immediately prior to the effective date of Employee's
        termination; or

            (iii)     Solicit or attempt to solicit business of any client of
        Employer (unless such solicitations are rendered as an employee of
        Employer) or render services (other than on behalf of Employer) for
        any such client which are competitive with those services which
        Employer performed for such client within ninety (90) days of the end
        of the Employment Term.

             (iv)     As used in this paragraph 7(b), the term "client" shall
        include anyone who is then a client or customer of Employer and anyone
        who was a client or customer at any time during the one year period
        immediately preceding the end of the Employment Term, as well as
        prospective clients or customers with whom Employer has been
        negotiating to become a client or customer within a one year period
        immediately preceding the end of the Employment Term.

Employee acknowledges and agrees that these restrictions are reasonable in
light of the

                                       6
<PAGE>

nature and scope of Employee's position, duties and responsibilities with
Employer, and the restrictions set forth in this paragraph 7 are necessary to
protect the legitimate business interests of Employer.

     (d)     Enforcement to Extent Lawfully Possible.  If any of the covenants
or terms contained paragraphs 5 or 7 are held to be unenforceable because of
the duration of such covenant, the area covered thereby or for any other
perceived overinclusiveness, the parties agree that the duration of such
provision, the area covered thereby, or such other perceived overinclusiveness
shall be reduced to the maximum scope permitted by law, and, in its reduced
form, shall be enforceable.

     8.     Injunctive and Other Relief.  The parties hereto recognize that
the services to be rendered under this Agreement by Employee to Employer are
special, unique and of extraordinary character, that maintaining the
confidential nature of the Confidential Information possessed and to be
possessed by Employee is crucial to the success of Employer's business and
that any breach by Employee of the provisions of paragraphs  5 or 7 of this
Agreement may cause irreparable damage to Employer for which damages at law
will be inadequate.  Therefore, in the event of any breach or threatened
breach by Employee of the provisions of paragraphs 5 or 7 of this Agreement,
then, in addition to any other remedy that may be available to it, Employer
shall be entitled to injunctive relief without the necessity of proving actual
damages and without posting bond or other security, as well as to an equitable
accounting of all earnings, profits and other benefits arising out of a breach
of paragraphs 5 or 7.  Employee also expressly agrees to indemnify and hold
Employer harmless from all losses, damages, costs, expenses and liabilities,
including attorney's fees, incurred as a result of any breach by Employee of
this Agreement.  In the event of any legal action by either Employer or
Employee to enforce this Agreement, if the party bringing such action prevails
(as determined by the adjudicator), such party shall be entitled to recover
from the other party its reasonable costs and expenses (including attorney's
fees); provided, however, nothing herein shall require the adjudicator to
determine that any party is the prevailing party.

     9.     Severability of Provisions.  If any of the provisions of this
Agreement shall be held invalid or unenforceable, the remainder of the
provisions of this Agreement shall not be affected thereby and shall be given
full effect, without regard to the invalid portions.

     10.     Assignment.  This Agreement is a personal contract and, except as
specifically set forth herein, the rights and interests of Employee herein may
not be sold, transferred, assigned, pledged or hypothecated.  The rights and
benefits of Employer under this Agreement shall be transferrable by Employer,
and all the covenants and agreements of Employee hereunder shall inure to the
benefit of and be enforceable by

                                       7
<PAGE>

Employer's successors and assigns.  The obligations of Employee hereunder are
binding upon Employee and Employee's heirs, successors, assigns, and legal
representatives.

     11.     Entire Agreement; Prior Agreements; Changes; Governing Law and
Captions.  This Agreement contains the entire agreement between the parties,
superseding all prior understandings, arrangements and agreements, whether
oral or written, relating to Employee's employment by Employer and all other
subjects addressed herein.  It may only be changed, amended, modified, waived,
or discharged in written agreement signed by the party against whom
enforcement of any waiver, change, addition, modification or discharge is
sought and, in the case where Employer is sought to be bound, must be approved
in writing by the Board of Directors or designated officers of Employer prior
to such signed writing.  The waiver or discharge of any provision of this
Agreement shall only be effective in the specific instance and for the
specific purpose for which it was given.  This Agreement shall be interpreted,
governed by and construed in accordance with the substantive laws of the State
of Wisconsin, without regard to its choice of laws rules.  Paragraph headings
are for convenience of reference only and shall not be considered a part of
this Agreement.

     12.     Notices.  Except as expressly set forth herein, any notices or
other communications required or permitted hereunder shall be in writing and
shall be deemed effective when delivered in Employer's case to Kenneth A.
Hendricks, in person, or by telex or telecopier or, if mailed in the United
States, then three days after deposited in the mails, postage prepaid, in the
case of Employee addressed to him at:
