                             STOCKHOLDER'S AGREEMENT

      STOCKHOLDER'S AGREEMENT (this "Agreement"), dated as of January 17, 2000,
between the undersigned stockholder ("Stockholder") of Starbelly.com, Inc., a
Delaware corporation f/k/a TheZebra.com, Inc. (the "Company"), and HA-LO
Industries, Inc., an Illinois corporation ("Acquiror").

      WHEREAS, concurrently with the execution of this Agreement, the Company,
Acquiror and HA-LO Industries, Inc., a Delaware corporation and wholly owned
subsidiary of Acquiror ("Acquiror Sub"), have entered into an Agreement and Plan
of Merger and Plan of Reorganization (the "Merger Agreement"), providing for the
merger (the "Merger") of the Company with and into Acquiror Sub pursuant to the
terms and conditions of the Merger Agreement;

      WHEREAS, upon consummation of the Merger, the stockholders of the Company
(the "Stockholders") will receive a number of shares of Common Stock, no par
value, of Acquiror and/or a number of shares of Series A Convertible Preferred
Stock, no par value, of Acquiror (collectively, "Acquiror Stock") for each share
of capital stock of the Company owned by them;

      WHEREAS, Stockholder owns of record and beneficially shares of capital
stock of the Company as set forth on Schedule I hereto (the "Shares"); and

      WHEREAS, in order to induce Acquiror to enter into the Merger Agreement,
Stockholder has agreed, upon the terms and subject to the conditions set forth
herein, to vote the Shares and to deliver an irrevocable proxy to Acquiror to
vote the Shares at a meeting of the Company's stockholders, in favor of approval
and adoption of the Merger Agreement and the Merger.

      NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

      1. Defined Terms. All of the capitalized terms used herein but not
otherwise defined shall have the meanings specified in the Merger Agreement.

      2. Agreement to Vote Shares.

            (a) Stockholder agrees that during the period from the date hereof
      until the earlier of the Effective Time of the Merger and the termination
      of the Merger Agreement in accordance with its terms, Stockholder shall
      vote the Shares, in person or by proxy, at every meeting of the
      stockholders of the Company at which such matters are considered and at
      every adjournment thereof or by written consent in lieu of such meeting
      (i) in favor of the Merger, the adoption by the Company of the Merger
      Agreement and the approval of the other transactions contemplated by the
      Merger Agreement, (ii) against any merger agreement or merger (other than
      the Merger Agreement and the Merger), consolidation, combination, sale of
      substantial assets, reorganization, recapitalization, dissolution,
      liquidation or winding up of or by the Company or any other Competing
      Transaction (as defined in the Merger Agreement ) (collectively,
      "Alternative Transactions") or (iii) against any amendment of the
      Company's Articles of Incorporation of By-laws or


      other proposal or transaction involving the Company or any of its
      subsidiaries, which amendment or other proposal or transaction would in
      any manner impede, frustrate, prevent or nullify the Merger, the Merger
      Agreement or any of the other transactions contemplated by the Merger
      Agreement (collectively, "Frustrating Transactions"). Stockholder has
      delivered to Acquiror on the date hereof a proxy substantially in the form
      attached hereto as Annex A (the "Proxy"), which Proxy is irrevocable from
      the date hereof until the earlier of the Effective Time of the Merger and
      the termination of the Merger Agreement in accordance with its terms to
      the extent permitted under Delaware Law, and Acquiror agrees to vote the
      Shares subject to such Proxy (A) in favor of the Merger, the adoption by
      the Company of the Merger Agreement and the approval of the other
      transactions contemplated by the Merger Agreement, (B) against any
      Alternative Transaction, or (C) against any Frustrating Transaction.

            (b) If, at any time prior to the expiration of this Agreement,
      Stockholder, or a representative of Stockholder, is a member of the Board
      of Directors of the Company or an officer of the Company, subject to the
      Merger Agreement, nothing in this Agreement shall limit or restrict such
      director or officer from acting in his capacity and exercising his
      fiduciary duties and responsibilities as a director or officer of the
      Company, as the case may be. It is understood that this Agreement shall
      apply to Stockholder solely in its capacity as a stockholder of the
      Company and shall not apply to the director's or officer's actions,
      judgments or decisions as a director or officer of the Company.

      3. No Voting Trusts. Stockholder agrees that during the period from the
date hereof until the earlier of the Effective Time of the Merger and the
termination of the Merger Agreement, he or it will not, directly or indirectly,
and will not cause or permit any entity or person under Stockholder's control
to, deposit any of the Shares in a voting trust or subject any of its Shares to
or otherwise enter into any arrangement (written or oral) with respect to the
voting of the Shares inconsistent with this Agreement.

      4. Limitation on Dispositions and Proxies. During the period from the date
hereof until the earlier of the Effective Time of the Merger and the termination
of the Merger Agreement in accordance with its terms, Stockholder agrees not to
sell, assign, pledge, transfer or otherwise dispose of, or grant any proxies
with respect to any of the Shares (except for the Proxy or a proxy which is not
inconsistent with the terms of this Agreement, the Proxy or a sale, transfer or
other disposition to a party to hold the Shares subject to the terms of this
Agreement and any other agreement entered into pursuant to the Merger Agreement
and to which the Shares are subject) or take any other action that would in any
way restrict, limit or interfere with the performance of its obligations
hereunder or the transactions contemplated hereby.

      5. Specific Performance. Each party acknowledges that it will be
impossible to measure in money the damage to the other party if a party hereto
fails to comply with the obligations imposed by this Agreement, and that, in the
event of any such failure, the other party will not have an adequate remedy at
law or in damages. Accordingly, each party hereto agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages (including
without limitation pursuant to Section 9), is the appropriate remedy for any
such failure and will not oppose the granting of such relief on the basis that
the other party has an


                                     - 2 -


adequate remedy at law. Each party hereto agrees that it will not seek, and
agrees to waive any requirement for, the securing or posting of a bond in
connection with any other party's seeking or obtaining such equitable relief.

      6. Status of Stockholders. Stockholder represents to the Buyer that it is
either an officer, director or holder of 5% or more of the outstanding voting
securities of the Company or an Affiliate of an officer, director or holder of
5% or more of the outstanding voting securities of the Company.

      7. Taking Necessary Action; Further Action. Stockholder agrees that during
the period from the date hereof until the earlier of the Effective Time of the
Merger and the termination of the Merger Agreement in accordance with its terms,
he or it shall each use reasonable efforts to take all actions as may be
reasonably necessary or appropriate to effectuate the Merger as soon as possible
consistent with the terms of this Agreement and the Merger Agreement, including
(a) actions of Stockholder in his or its capacity as a stockholder of the
Company, and (b) making any required filings under (including with respect to
the acquisition by any Stockholder of shares of Acquiror Stock in the Merger),
and providing each other with information with respect to filings required
under, the HSR Act.

      8. Investment Representations. Shares of Acquiror Stock are being issued
by Acquiror to Stockholder in connection with the Merger in reliance upon the
following representations, warranties and agreements of Stockholder, each of
which shall be true and correct as of the date hereof and at the Effective Time,
and each of which shall survive the Effective Time.

            (a) Stockholder acknowledges that shares of Acquiror Stock issued
      and issuable to him or it at the Effective Time of the Merger will not
      have been registered under the Securities Act or under applicable state
      securities laws.

            (b) All shares of Acquiror Stock delivered or deliverable to
      Stockholder in the Merger are being acquired by Stockholder solely for
      investment purposes and for the account of Stockholder, and not as a
      nominee or agent for others or with a view to or for sale in connection
      with any distribution, and Stockholder has no present intention of selling
      or otherwise distributing such shares of Acquiror Stock and has not
      entered into any arrangement or understanding with respect thereto, except
      in each case in accordance with the terms of this Agreement, pursuant to
      the Registration Rights Agreement or otherwise in compliance with
      applicable securities laws.

            (c) The Stockholder acknowledges that his or its shares of Acquiror
      Stock must be held indefinitely unless subsequently registered under the
      Securities Act or an exemption from such registration is available. The
      Stockholder agrees that he or it shall not make a disposition of any
      shares of Acquiror Stock issued to him or it in the Merger unless such
      shares have been registered under the Securities Act, including without
      limitation in accordance with a Registration Rights Agreement with
      Acquiror, or are sold in accordance with an exemption from registration
      under Rule 144 or 144A under the Securities Act, or unless an exemption
      from the registration requirements of the Securities Act and applicable
      state securities laws (other than under Rule 144 or 144A) is available and
      Acquiror shall have received an opinion of counsel reasonably satisfactory


                                     - 3 -


      to Acquiror to the effect that such exemption from the registration
      requirements of the Securities Act is valid and available.

      Acquiror Stock is a speculative investment and is subject to significant
      risks, including the risks described in Acquiror's Registration Statement
      on Form S-3 dated December 10, 1999. The foregoing representation shall
      not limit any rights or remedies Stockholder may have under the Merger
      Agreement or otherwise in connection with the Merger. Stockholder
      represents and warrants to Acquiror that he or it is able to fend for
      himself or itself in the transactions contemplated by this Agreement, has
      such knowledge and expertise in financial and business matters as to be
      capable of evaluating the merits and risks of his or its investment and

                  10% of the voting power represented by the then outstanding
                  Acquiror Securities, unless such pledgee has agreed to sell
                  such Acquiror Securities in open-market transactions over a
                  national securities exchange, (B) enter into bona fide hedging

                  Acquiror Securities pursuant to an underwritten


                                     - 6 -


                  public offering or over a national securities exchange (other
                  than in prearranged block transactions); or

                  (viii) make any agreement to do any of the foregoing to the
                  extent restricted thereby.

            (b) Acquiror acknowledges and agrees that, solely as a result of
      Stockholder's execution of this Agreement and compliance with the
      provisions hereof, (i) neither Stockholder nor its Affiliates shall, and
      neither Stockholder nor its Affiliates shall be deemed to, be acting
      together or agreeing to act together with any other person or entity with
      respect to Acquiror Securities, and (ii) Stockholder has not acted other
      than independently and individually, without regard to the purposes or
      intention of any other person or entity and without the purpose or intent
      of acting together with any other person or entity for any reason. With
      respect to obligations of Stockholder pursuant to any provision of this
      Section 9 qualified by the "knowledge" of Stockholder, it is understood
      and agreed that upon receipt by Stockholder of notice from Acquiror that
      Stockholder has breached a provision of this Section 9 (notwithstanding
      any requirement relating to knowledge of Stockholder contained in such
      provision), Stockholder's receipt of such notice shall evidence the
      requisite knowledge of Stockholder under this Section 9 with respect to
      such activities constituting a breach on a going forward basis, and
      Stockholder shall be required to use its reasonable best efforts to
      promptly remedy any such activities which so constitute a breach without
      regard to the knowledge qualifier, whether or not such breach is then
      continuing.

            (c) If at any time during the Restricted Period, Stockholder and its
      Affiliates "beneficially own" (as defined in Rule 13d-3 under the Exchange
      Act) in the aggregate less than five percent (5%) of the voting power
      represented by the fully diluted Acquiror Securities then outstanding,
      Stockholder and its Affiliates shall no longer be subject to the
      provisions of this Section 9; provided, that if at any time following such
      occurrence, Stockholder and its Affiliates "beneficially own" (as defined
      in Rule 13d-3 under the Exchange Act) in the aggregate five percent (5%)
      or more of the voting power represented by the fully diluted Acquiror
      Securities then outstanding, the provisions of this Section 9 shall once
      again apply and be in full force and effect with respect to Stockholder
      and its Affiliates for the remainder of the Restriction Period, if any.

            (d) Notwithstanding Section 5 hereof, Acquiror shall not be
      restricted from seeking or obtaining monetary damages from Stockholder for
      breach of this Section 9, up to a maximum of $5.0 million; provided that
      such $5.0 million maximum liability shall be a joint cap applicable to the
      aggregate liability of Stockholder under this Section 9 and of Coventry
      Partners Family L.P., a Delaware limited partnership, under Section 9 of
      that certain Stockholders Agreement between Coventry Partners Family L.P.
