                                   EXHIBIT A

                              SMARTAGE.COM CORP.

                           INDEMNIFICATION AGREEMENT

     THIS INDEMNIFICATION AGREEMENT (the "Agreement"), effective as of _______,
2000, by and between, SMARTAGE.COM CORP., a Delaware corporation (the
                      -----------------
"Company"), and _____________________ (the "Indemnitee").

     1.   Indemnification.  The Company shall indemnify Indemnitee to the
          ---------------
fullest extent permitted by section 145 of the Delaware General Corporation Law,
as amended (the "Delaware Law"), the Certificate of Incorporation (the
"Certificate") and the Bylaws of the Company (the "Bylaws") in effect on the
date hereof or as such Law, Certificate, and Bylaws may from time to time be
amended (but, in the case of any such amendment, only to the extent such
amendment permits the Company to provide broader indemnification rights than the
Law, Certificate or Bylaws permitted the Company to provide before such
amendment), if and whenever he is or was a party or is threatened to be made a
party to any Proceeding, against Expenses and Liabilities actually and
reasonably incurred by Indemnitee or on his behalf in connection with the
investigation, defense, settlement or appeal of such Proceeding. The right to
indemnification conferred herein shall be presumed to have been relied upon by
Indemnitee in serving or continuing to serve the Company as an officer or
director and shall be enforceable as a contract right. Without in any way
diminishing the scope of the indemnification provided by this Section 1, the
Company will indemnify Indemnitee if Indemnitee:

     (a)  was or is a party or is threatened to be made a party to any
Proceeding (other than an action by or in the right of the Company to procure a
judgment in its favor) by reason of the fact Indemnitee is or was an Agent,
against Expenses and Liabilities actually and reasonably incurred in connection
with such Proceeding if Indemnitee acted in good faith and in a manner
reasonably believed to be in the best interests of the Company and, in the case
of a criminal proceeding, had no reasonable cause to believe his conduct was
unlawful. The termination of any Proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that Indemnitee did not act in good faith and in a
manner which Indemnitee reasonably believed to be in the best interests of the
Company or that Indemnitee had reasonable cause to believe that Indemnitee's
conduct was unlawful, or

     (b)  was or is a party or is threatened to be made a party to any
threatened, pending or completed action by or in the right of the Company to
procure a judgment in its favor by reason of the fact that Indemnitee is or was
an agent of the Company, against Expenses and Liabilities actually and
reasonably incurred by Indemnitee in connection with the defense or settlement
of such action if Indemnitee acted in good faith, in a manner Indemnitee
believed to be in the best interests of the Company and its stockholders.

     (c)  to the extent that Indemnitee has been successful on the merits in
defense of any Proceeding referred to in clause (a) or (b) above or in defense
of any action, claim, issue or matter therein, Indemnitee shall be indemnified
against Expenses actually and reasonably incurred by Indemnitee in connection
therewith.

                                      -1-
<PAGE>

     In addition to, and not as a limitation of, the foregoing, the rights of
indemnification of Indemnitee provided under this Agreement shall include those
rights set forth below.

     2.   Advancement of Expenses and Costs. All reasonable Expenses incurred by
          ---------------------------------
or on behalf of Indemnitee shall be advanced by the Company to Indemnitee within
thirty (30) calendar days after the receipt by the Company of a statement or
statements from Indemnitee requiring an advance or advances of Expenses from
time to time, whether prior to or after final disposition of such Proceeding.
The statement or statements shall reasonably evidence the Expenses incurred or
to be incurred by him in connection therewith. If required by law at the time of
such advance, Indemnitee hereby undertakes to repay the amounts advanced if it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
pursuant to the terms of this Agreement.

     3.   Other Rights to Indemnification. Indemnitee's rights of
          -------------------------------
indemnification and advancement of expenses provided by this Agreement shall not
be deemed exclusive of any other rights to which Indemnitee may now or in the
future be entitled under applicable law, the Certificate, Bylaws, agreement,
vote of stockholders, resolution of directors, or otherwise.

     4.   Limitations on Indemnity.  Any provision herein to the contrary
          ------------------------
notwithstanding, the Company shall not be obligated pursuant to this Agreement:

     (a)  Insured Claims.  To make any payment to Indemnitee to the extent that
          --------------
Indemnitee is indemnified other than pursuant to this Agreement or to the extent
that Indemnitee is reimbursed pursuant to any director and officer insurance or
other insurance the Company may maintain for Indemnitee's benefit; provided,
however, that notwithstanding the availability of such insurance, Indemnitee may
claim indemnification pursuant to this Agreement by assigning to the Company, at
its request, any claims under such insurance to the extent Indemnitee is paid by
the Company.

     (b)  Claims Initiated by Indemnitee.  To indemnify or advance expenses to
          ------------------------------
Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Delaware Law, but such indemnification or advancement of Expenses may be
provided by the Company in specific cases if the Board of Directors has approved
the initiation or bringing of such suit.

     (c)  Claims Under Section 16(b).  To indemnify Indemnitee for Expenses and
          --------------------------
the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     5.   Duration of Agreement.  This Agreement shall continue so long as
          ---------------------
Indemnitee shall be subject to any possible Proceeding by reason of the fact
that he is or was an Agent.  This Agreement shall be binding upon the Company
and its successors and assigns and shall inure to the benefit of Indemnitee and
his spouse, assigns, heirs, devisees, executors, administrators or other legal
representatives.

     6.   Miscellaneous.
          -------------

     (a)  Procedure.  Any indemnification and advances provided for in Sections
          ---------
1 and 2 shall be made no later than thirty (30) calendar days, respectively,
after receipt of a written request therefor of Indemnitee. If a claim under this
Agreement, under any statute, or under any provision of the Company's
Certificate or Bylaws providing for indemnification, is not paid in full by the
Company within such period, Indemnitee may, but need not, at any time thereafter
bring an action against the Company to recover the unpaid amount of the claim
and, subject to Section 6(l) of this Agreement, Indemnitee shall also be
entitled to be paid for the Expenses (including attorney's fees) of bringing
such action. It shall be a defense to any such action (other than an action
brought to enforce a claim for Expenses incurred in connection with any action
or proceeding in advance of its final disposition) that Indemnitee has not met
the standards of conduct which make it permissible under applicable law for the
Company to indemnify Indemnitee for the amount claimed, and Indemnitee shall be
entitled to receive interim payments of expenses pursuant to Section 2 unless
and until such defense is finally adjudicated by court order or judgment from
which no further right of appeal exists. It is the parties' intention that if
the Company contests Indemnitee's right to indemnification, the Company shall be
entitled to select the forum in which Indemnitee's entitlement to
indemnification will be heard. The Company shall notify the Indemnitee in
writing as to the forum selected, which selection shall be from among the
following:

          (i)   The stockholders of the Company;

          (ii)  A quorum of the Board consisting of Disinterested
     Directors;

          (iii) Independent Counsel selected by Indemnitee, and
     reasonably approved by the Board, which counsel shall make the
     determination in a written opinion; or

          (iv)  A panel of three arbitrators, one of whom is selected
     by the Company, another of whom is selected by Indemnitee and
     the last of whom is selected by the first two arbitrators so
     selected; or if for any reason three arbitrators are not
     selected within thirty (30) days after the appointment of the
     first arbitrator, then selection of additional arbitrators to
     complete the three person panel shall be made by the American
     Arbitration Association under its commercial arbitration rules
     now in effect.

     Neither the failure of the Company (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholder) to have made a determination that indemnification of Indemnitee
is proper in the circumstances because Indemnitee has met the applicable
standard of conduct required by applicable law, nor an actual determination by
the Company (including its Board of Directors, any committee or subgroup of the
Board of Directors, independent legal counsel, or its stockholders) that
Indemnitee has not met such applicable standard of conduct, shall create a
presumption that Indemnitee has or has not met the applicable standard of
conduct.

                                      -3-
<PAGE>

     (b)  Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------
that in certain instances, federal or state law or applicable public policy may
prohibit the Company from indemnifying its directors and officers under this
Agreement or otherwise.  Indemnitee understands and acknowledges that the
Company has undertaken or may be required in the future to undertake with the
Securities and Exchange Commission to submit the question of indemnification to
a court in certain circumstances for a determination of the Company's right
under public policy to indemnify Indemnitee.

     (c)  Severability.  If any provision or provisions of this Agreement shall
          ------------
be held to be invalid, illegal or unenforceable for any reason whatsoever:  (i)
the validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any provision held to be invalid, illegal or unenforceable,
that are not themselves invalid, illegal or unenforceable) shall not in any way
be affected or impaired thereby; and (ii) to the fullest extent possible, the
provisions of this Agreement (including, without limitation, all portions of any
paragraph of this Agreement containing any provision held to be invalid, illegal
or unenforceable, that are not themselves invalid, illegal or unenforceable)
shall be construed so as to give effect to the intent manifested by the
provision held invalid, illegal or unenforceable.

     (d)  Identical Counterparts.  This Agreement may be executed in one or more
          ----------------------
counterparts, each of which shall for all purposes be deemed to be an original
but all of which together shall constitute one and the same Agreement.  Only one
such counterpart signed by the party against whom enforceability is sought needs
to be produced to evidence the existence of this Agreement.

     (e)  Interpretation of Agreement.  It is understood that the parties hereto
          ---------------------------
intend this Agreement to be interpreted and enforced so as to provide
indemnification to Indemnitee to the fullest extent now or hereafter permitted
by law.

     (f)  Headings.  The headings of the paragraphs of this Agreement are
          --------
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

     (g)  Definitions.  For purposes of this Agreement:

     or other official of another enterprise at the request of, for
     the convenience of, or to represent the interests of such

     actually and reasonably incurred in connection with either the
     investigation, defense, settlement or appeal of a Proceeding or
     establishing or enforcing a right to indemnification under this
     Agreement, applicable law or otherwise; provided, however, that
     expenses shall not include any judgments, fines, ERISA excise
     taxes or penalties or amounts paid in settlement of a Proceeding.

          (iii) "Liabilities" shall mean liabilities of any type
                 -----------
     whatsoever, including, but not limited to, judgments, fines,
     ERISA excise taxes and penalties and amounts paid in settlement
     of a Proceeding.

          (iv)  "Proceeding" shall mean any action, suit arbitration,
                 ----------
     alternate dispute resolution mechanism, investigation,
     administrative hearing or any other proceeding whether civil,
     criminal, administrative or investigative to which Indemnitee is
     or was a party or is threatened to be a party by reason of the
     fact that he is or was an Agent or by reason of anything done or
     not done by Indemnitee in such capacity.

          (v)   "Delaware Law" shall mean Title 8 of the Delaware Code
                 ------------

parties to this Agreement.  No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.

     (j)  Notice by Indemnitee and Defense of Claims.  Indemnitee agrees
          ------------------------------------------
promptly to notify the Company in writing upon being served with any summons,
citation, subpoena, complaint, indictment, information or other document
relating to any matter which may be subject to indemnification covered
hereunder, either civil, criminal or investigative; but the omission so to
notify the Company will not relieve it from any liability which it may have to
Indemnitee if such omission does not prejudice the Company's rights and if such
omission does prejudice the Company's rights, it will relieve the Company from
liability only to the extent of such prejudice; nor will such omission, in any
event, relieve the Company from any liability which it may have to Indemnitee
otherwise than under this Agreement. With respect to any Proceeding as to which
Indemnitee notifies the Company of the commencement thereof:

                                      -5-
<PAGE>

          (i)   The Company will be entitled to participate therein at
     its own expense; and

          (ii)  Except as otherwise provided below, to the extent that
     it may wish, the Company jointly with any other indemnifying
     party similarly notified will be entitled to assume the defense
     thereof, with counsel reasonably satisfactory to Indemnitee.
     After notice from the Company to Indemnitee of its election so to
     assume the defense thereof, the Company will not be liable to
     Indemnitee under this Agreement for any legal or other expenses
     subsequently incurred by Indemnitee in connection with the
     defense thereof except as otherwise provided below. Indemnitee
     shall have the right to employ his counsel in such action, suit
     or proceeding but the fees and expenses of such counsel incurred
     after notice from the Company of its assumption of the defense
     thereof shall be at the expense of Indemnitee unless (A) the
     employment of counsel by Indemnitee has been authorized by the
     Company, or (B) the Company shall not in fact have employed
     counsel to assume the defense of such action, in each of which
     cases the fees and expenses of counsel shall be at the expense of
     the Company, or (C) Indemnitee shall have reasonably concluded
     that there may be a conflict of interest between the Company and
     Indemnitee in the conduct of any such defense.

          (iii) The Company shall not be liable to indemnify
     Indemnitee under this Agreement for any amounts paid in
     settlement of any action or claim effected without its written
     consent. The Company shall not settle any action or claim in any
     manner which would impose any penalty or limitation on Indemnitee
     without Indemnitee's written consent. Neither the Company nor
     Indemnitee will unreasonably withhold their consent to any
     proposed settlement.

     (k)  Notices.  All notices, requests, demands and other communications
          -------
hereunder shall be in writing and shall be deemed to have been duly given if (i)
delivered by hand and receipted for by the party to whom said notice or other
communication shall have been directed or (ii) mailed by certified or registered
mail with postage prepaid, on the third business day after the date on which it

     (l)  Attorneys' Fees.  In the event that any action is instituted by
          ---------------
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous.  In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all court costs and expenses, including attorneys' fees, incurred by
Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

     (m)  Consent to Jurisdiction.  The Company and Indemnitee each hereby
          -----------------------
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of Delaware.

     (n)  Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred by him in the investigation, defense, appeal or settlement of any
Proceeding, but not, however, for the total amount thereof, the Company shall
nevertheless indemnify Indemnitee for the portion of such expenses, judgments,
fines or penalties to which Indemnitee is entitled.

     (o)  Governing Law; Binding Effect.  The parties agree that this Agreement
          -----------------------------
shall be governed by, and construed and enforced in accordance with, the laws of
the State of Delaware, as applied to contracts between Delaware residents
entered into and to be performed entirely within Delaware.  This Agreement shall
be binding upon Indemnitee and upon the Company, its successors and assigns, and
shall inure to the benefit of Indemnitee, his heirs, personal representatives
and assigns and to the benefit of the Company, its successors and assigns.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.
